72291a9d83 efi_loader: fix freestanding memmove()
For EFI binaries we have to provide an implementation of memmove() in
efi_freestanding.c.

Before this patch the memmove() function was copying in the wrong

e0d310b098 lib: rsa: generate additional parameters for public key
In the current implementation of FIT_SIGNATURE, five parameters for
a RSA public key are required while only two of them are essential.
(See rsa-mod-exp.h and uImage.FIT/signature.txt)
This is a result of considering relatively limited computer power
and resources on embedded systems, while such a assumption may not
be quite practical for other use cases.

In this patch, added is a function, rsa_gen_key_prop(), which will
generate additional parameters for other uses, in particular
UEFI secure boot, on the fly.

Note: the current code uses some "big number" routines from BearSSL
for the calculation.

b484296f6f efi_loader: get_memory_map: return parameters whenever possible
Currently, if GetMemoryMap API returns EFI_BUFFER_TOO_SMALL, it doesn't
set valid values to other parameters, descriptor_size and
descriptor_version, except memory_map_size.
Some efi applications, however, may use those value; in particular,
xen uses descriptor_size to calculate a size of buffer to be allocated.

While UEFI specification is ambiguous in this point, it would be better
to address this issue proactively to maximize the compatibility with
existing efi applications.

With this patch, for example, xen.efi (and hence linux kernel) can be
started via bootefi without modification.

479ab6c17e efi_selftest: add selftests for loadfile2 used to load initramfs
Provide a unit test loading an initial ramdisk using the
EFI_LOAD_FILE2_PROTOCOL. The test is only executed on request.

An example usage - given a file image with a file system in partition 1
holding file initrd - is:

* Configure the sandbox with

  CONFIG_EFI_SELFTEST=y
  CONFIG_EFI_LOAD_FILE2_INITRD=y
  CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd"

* Run ./u-boot and execute

    host bind 0 image
    setenv efi_selftest load initrd
    bootefi selftest

This would provide a test output like:

    Testing EFI API implementation

    Selected test: 'load initrd'

    Setting up 'load initrd'
    Setting up 'load initrd' succeeded

    Executing 'load initrd'
    Loaded 12378613 bytes
    CRC32 2997478465
    Executing 'load initrd' succeeded

Now the size and CRC32 can be compared to the provided file.

ec80b4735a efi_loader: Implement FileLoad2 for initramfs loading
Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.

The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

e8c2d25845 libfdt: Revert 6dcb8ba4 from upstream libfdt
In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing
unaligned words" introduced changes to support unaligned reads for ARM
platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned
reads on ARM" improved the performance of these helpers.

In practice however, this only occurs when the user has forced the
device tree to be placed in memory in a non-aligned way, which in turn
violates both our rules and the Linux Kernel rules for how things must
reside in memory to function.

This "in practice" part is important as handling these other cases adds
visible (1 second or more) delay to boot in what would be considered the
fast path of the code.

570147275c efi_loader: adjust file system info
When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve
the file system info we claim that the volume is read only and has no free
space. This leads to failures in programs that check this information
before writing to the volume like SCT's InstallSct.efi.

Currently there is no function to determine these parameters in U-Boot. So
let's return optimistic values:

Return that the volume is writable.

Return the volume size as free space.

77dd7c6854 x86: timer: use a timer base of 0
On x86 platforms the timer is reset to 0 when the SoC is reset. Having
this as the timer base is useful since it provides an indication of how
long it takes before U-Boot is running.

When U-Boot sets the timer base to something else, time is lost and we
no-longer have an accurate account of the time since reset. This
particularly affects bootstage.

Change the default to not read the timer base, leaving it at 0. Add an
option for when U-Boot is the secondary bootloader.

fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().

UEFI on ARM requires that unaligned memory access is enabled.

* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
  U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
  which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
  For none of the other cpus in arch/arm/cpu/ we have implemented a
  similar function.
* ARMv8 allows unaligned access.

Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.

Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.

6ccb05eae0 image: fdt: copy possible optee nodes to a loaded devicetree
The loading convention for optee or any other tee on arm64 is as bl32
parameter to the trusted-firmware. So TF-A gets invoked with the TEE as
bl32 and main u-boot as bl33. Once it has done its startup TF-A jumps
into the bl32 for the TEE startup, returns to TF-A and then jumps to bl33.

All of them get passed a devicetree as parameter and all components often
get loaded from a FIT image.

OP-TEE will create additional nodes in that devicetree namely a firmware
node and possibly multiple reserved-memory nodes.

While this devicetree is used in main u-boot, in most cases it won't be
the one passed to the actual kernel. Instead most boot commands will load
a new devicetree from somewhere like mass storage of the network, so if
that happens u-boot should transfer the optee nodes to that new devicetree.

To make that happen introduce optee_copy_fdt_nodes() called from the dt
setup function in image-fdt which after checking for the optee presence
in the u-boot dt will make sure a optee node is present in the kernel dt
and transfer any reserved-memory regions it can find.

But in the early code checking for an already existing carveout this check
was not done and thus the phandle assignment could run into trouble,
so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to
work with the phandle.

4d579a4394 libavb: Update libavb to current AOSP master
Update libavb to commit 5fbb42a189aa in AOSP/master, because new version
has support for super partition [1], which we need for implementing
Android dynamic partitions. All changes from previous patches for libavb
in U-Boot are accounted for in this commit:
  - commit ecc6f6bea6 ("libavb: Handle wrong hashtree_error_mode in
                          avb_append_options()")
  - commit 897a1d947e ("libavb: Update SPDX tag style")
  - commit d8f9d2af96 ("avb2.0: add Android Verified Boot 2.0 library")

Tested on X15:

    ## Android Verified Boot 2.0 version 1.1.0
    read_is_device_unlocked not supported yet
    read_rollback_index not supported yet
    read_is_device_unlocked not supported yet
    Verification passed successfully
    AVB verification OK.

Unit test passes:

9b3fbb2b43 tiny-printf: Support vsnprintf()
Add a simple implementation of this function, to allow logging to be

To keep the code size small,

- The function is built only when logging is enabled, as it

- Like the existing implementation of snprintf(), its buffer-size

1b7313d91f efi_selftest: testing read-only variables
The UEFI spec has this sentence:
"Variables that have runtime access but that are not nonvolatile are
read-only data variables once ExitBootServices() is performed."

At least EDK2 therefore treats variable PlatformLangCodes only as read-only
at runtime. Nowhere do we make this variable read-only in U-Boot.

Do not use variable PlatformLangCodes for testing if the read only
attribute of variables is observed before ExitBootServices().

23ad52fff4 efi_loader: device_path: support Sandbox's "host" devices
Sandbox's "host" devices are currently described as UCLASS_ROOT udevice
with DEV_IF_HOST block device. As the current implementation of
efi_device_path doesn't support such a type, any "host" device
on sandbox cannot be seen as a distinct object.

For example,
  => host bind 0 /foo/disk.img

  => efi devices
  Scanning disk host0...
  Found 1 disks

  0000000015c19d70 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)

  => efi dh
  Handle           Protocols
  ================ ====================
  0000000015c19970 Device Path, Device Path To Text, Device Path Utilities, Unicode Collation 2, HII String, HII Database, HII Config Routing
  0000000015c19ba0 Driver Binding

  0000000015c19c80 Simple Text Input, Simple Text Input Ex
  0000000015c19d70 Block IO, Device Path, Simple File System

As you can see here, efi_root (0x0000000015c19970) and host0 device
(0x0000000015c19d70) have the same representation of device path.

This is not only inconvenient, but also confusing since two different
efi objects are associated with the same device path and
efi_dp_find_obj() will possibly return a wrong result.

Solution:
Each "host" device should be given an additional device path node
of "vendor device path" to make it distinguishable.

Commit c7b3a7ee53 ("optee: adjust dependencies and default values for

This patch makes the following defines contingent on CONFIG_OPTEE=y

CONFIG_OPTEE_TZDRAM_SIZE

Rightly, if you don't have CONFIG_OPTEE=y you don't care about the above

b225c92fd0 efi_loader: Change return type of efi_add_memory_map()
We currently have some inconsistent use of efi_add_memory_map()
throughout the code. In particular the return value of efi_add_memory_map()
is not interpreted the same way by various users in the codebase.

This patch does the following:

- Changes efi_add_memory_map() to return efi_status_t.
- Adds a method description to efi_add_memory_map().
- Changes efi_add_memory_map() to return EFI_SUCCESS
- Returns non-zero for error in efi_add_memory_map()
- Updates efi_allocate_pages() to new efi_add_memory_map()
- Updates efi_free_pages() to new efi_add_memory_map()
- Updates efi_carve_out_dt_rsv() to new efi_add_memory_map()
- Updates efi_add_runtime_mmio()  to new efi_add_memory_map()

2a51e16bd5 configs: Make USE_TINY_PRINTF depend on SPL||TPL and be default
The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support.  Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.

To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol.  Finally, in
the case of a few boards we really do need the full printf
functionality.

f2980ece06 sandbox: Quit when hang() is called
It doesn't make a lot of sense to hang on sandbox when hang() is called,
since the only way out is Ctrl-C. In fact, Ctrl-C does not work if the
terminal is in raw mode, which it will be if the command-line has not been
reached yet. In that case, Ctrl-Z / kill -9 must be used, which is not
very friendly.

Avoid all of this by quiting when hang() is called.

7a69e97ba4 efi_loader: implement event queue
Up to now we have only been using a flag queued for events. But this does
not satisfy the requirements of the UEFI spec. Events must be notified in
the sequence of decreasing TPL level and within a TPL level in the sequence
of signaling.

Implement a queue for signaled events.

7eaa900e56 efi_loader: event signaling in ExitBootServices
ExitBootServices() has to stop timer related activity before calling the
events of the EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. But our
current implementation was stopping all other events.

All events have to observe the task priority level.

5973901826 Merge branch 'master' of git://git.denx.de/u-boot-tegra
The bulk of these changes are an effort to unify Tegra186 builds with
builds of prior 64-bit Tegra generations. On top of that there are
various improvements that allow data (such as the MAC address and boot
arguments) to be passed through from early firmware to the kernel on
boot.

3bad256f5b lib/vsprintf: allow printing upper case GUIDs
In the UEFI context GUIDs are expected to be rendered in upper case.

The patch uses the formerly unused bit 1 of the parameter str_format
of function uuid_bin_to_str() to indicate if we need upper or lower case
output.

Function uuid_string() in vsprint.c is adjusted to correctly set the bit
depending on the print format code.

%pUb: 01020304-0506-0708-090a-0b0c0d0e0f10

%pUL: 04030201-0605-0807-090A-0B0C0D0E0F10

Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is
concerned by the change. Further patches are needed to adjust the UEFI
subsystem.

This function can be used to set the local MAC address for the default
Ethernet interface in its device tree node. The default interface is

One case where this is useful is for devices that store their MAC

MAC address in U-Boot's control DTB so that it will automatically be

The device path to text protocol renders ACPI device nodes incorrectly.

Use capital hexadecimal numbers as shown in the UEFI spec examples.

Always output the optional UID. This matches what UEFI SCT expects and

3b985113be efi_loader: infinite recursion notifying events
UEFI SCT uses this call sequence to determine the current TPL level inside
notification functions:

    OldTpl = BS->RaiseTPL(TPL_HIGH_LEVEL);
    BS->RestoreTPL(OldTpl);

In RestoreTPL() we trigger the notification function of queued events. If
we do not mark the event as non-queued before calling the notification
function, this results in an infinite recursive call sequence.

Mark the event as non-queued before entering the notification function.

4ccf678f37 lib: uuid: Fix unseeded PRNG on RANDOM_UUID=y
The random uuid values (enabled via CONFIG_RANDOM_UUID=y) on our
platform are always the same. Below is consistent on each cold boot:

 => ### interrupt autoboot
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=d117f98e-6f2c-d04b-a5b2-331a19f91cb2
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=ad5ec4b6-2d9f-8544-9417-fe3bd1c9b1b3
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=cceb0b18-39cb-d547-9db7-03b405fa77d4
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=d4981a2b-0478-544e-9607-7fd3c651068d
 => env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
 ...
 uuid_gpt_misc=6d6c9a36-e919-264d-a9ee-bd00379686c7

While the uuids do change on every 'gpt write' command, the values
appear to be taken from the same pool, in the same order.

Assuming U-Boot with RANDOM_UUID=y is deployed on a large number of
devices, all those devices would essentially expose the same UUID,
breaking the assumption of system/RFS/application designers who rely
on UUID as being globally unique (e.g. a database using UUID as key
would alias/mix up entries/records due to duplicated UUID).

The root cause seems to be simply _not_ seeding PRNG before generating
a random value. It turns out this belongs to an established class of
PRNG-specific problems, commonly known as "unseeded randomness", for
which I am able to find below bugs/CVE/CWE:
 - https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-0285
   ("CVE-2015-0285 openssl: handshake with unseeded PRNG")
 - https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-9019
   ("CVE-2015-9019 libxslt: math.random() in xslt uses unseeded
   randomness")
 - https://cwe.mitre.org/data/definitions/336.html
   ("CWE-336: Same Seed in Pseudo-Random Number Generator (PRNG)")

The first revision [1] of this patch updated the seed based on the
output of get_timer(), similar to [4].

There are two problems with this approach:
 - get_timer() has a poor _ms_ resolution
 - when gen_rand_uuid() is called in a loop, get_timer() returns the
   same result, leading to the same seed being passed to srand(),
   leading to the same uuid being generated for several partitions
   with different names

The above drawbacks have been addressed in the second version [2].
In its third revision (current), the patch reworded the description
and summary line to emphasize it is a *fix* rather than an improvement.

Testing [3] consisted of running 'gpt write mmc 1 $partitions' in a
loop on R-Car3 for several minutes, collecting 8844 randomly generated
UUIDS. Two consecutive cold boots are concatenated in the log.
As a result, all uuid values are unique (scripted check).

Thanks to Roman, who reported the issue and provided support in fixing.

Pull request for UEFI sub-system for v2019.07-rc1 (3)

This patch series reworks the implementation of the `bootefi` command to
remove code duplication by using the LoadImage() boot service to load
binaries.

Missing short texts for UEFI protocols are added for display by the
`efidebug dh` command.

Missing parameter checks for AllocatePages() and CreateDeviceNode() are
implemented.

The constants for protocol GUIDs are changed to match the names in the UEFI
specification.

829ceb2821 image: android: allow booting lz4-compressed kernels
According to Android image format [1], kernel image resides at 1 page
offset from the boot image address. Grab the magic number from there
and allow U-Boot to handle LZ4-compressed KNL binaries instead of
hardcoding compression type to IH_COMP_NONE. Other compression types,
if needed, can be added later.

Tested on H3ULCB-KF using the image detailed in [2].

This function may be called from tracing code, since that code needs to
read the timer and this often requires calling do_div(), which calls

6b95b38c41 efi_loader: rework bootmgr/bootefi using load_image API
In the current implementation, bootefi command and EFI boot manager
don't use load_image API, instead, use more primitive and internal
functions. This will introduce duplicated code and potentially

Split fdtdec_setup_mem_size_base() into fdtdec_setup_mem_size_base_fdt(),
which allows the caller to pass custom blob into the function and the
original fdtdec_setup_mem_size_base(), which uses the gd->fdt_blob. This
is useful when configuring the DRAM properties from a FDT blob fragment
passed in by the firmware.

8458bf648f efi_loader: set image_base and image_size to correct values
Currently, image's image_base points to an address where the image was
temporarily uploaded for further loading. Since efi_loader relocates
the image to final destination, image_base and image_size should reflect
that.

This bug was detected in UEFI SCT, "Loaded Image Protocol Test - test 2,"
which shows that 'Unload' function doesn't fit into a range suggested by
image_base and image_size.

	LoadedImageBBTestMain.c:1002

Changes in this patch also includes:
* reverts a patch, "efi_loader: save image relocation address

* copy PE headers as well since those information will be needed
  for module loading, in particular, at gurb.

5fbb28958b efi_loader: Make HII a config option
Heinrich ran into issues with HII and iPXE which lead to #SErrors on
his Odroid-C2 system. We definitely do not want to regress just yet,
so let's not expose the HII protocols by default.

Instead, let's make it a config option that people can play with
This way, we can stabilize the code in tree without breaking any
users.

Once someone figures out, why this breaks iPXE (probably a NULL
dereference), we can enable it by default.

47870afab9 initcall: Move to inline function
The board_r init function was complaining that we are looping through
an array, calling all our tiny init stubs sequentially via indirect
function calls (which can't be speculated, so they are slow).

The solution to that is pretty easy though. All we need to do is inline
the function that loops through the functions and the compiler will
automatically convert almost all indirect calls into direct inlined code.

With this patch, the overall code size drops (by 40 bytes on riscv64)

to think that there was no previously deleted entry. It then conluded
that a free entry was found, even if there were no free entries and it
overwrote a random entry.

This patch makes sure all deleted or free entries are always found and
also introduces constants for the 0 and -1 numbers. Unit tests to excersise a
simple hash table usage and catch the corruption were added.

To trash your environment, simply run this loop:

4cc8af8037 lib: lmb: extend lmb for checks at load time
This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.

lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.

lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.

Added test for these new functions.

0f7c51a676 lib: lmb: reserving overlapping regions should fail
lmb_add_region handles overlapping regions wrong: instead of merging
or rejecting to add a new reserved region that overlaps an existing
one, it just adds the new region.

Since internally the same function is used for lmb_alloc, change
lmb_add_region to reject overlapping regions.

Also, to keep reserved memory correct after 'free', reserved entries
created by allocating memory must not set their size to a multiple
of alignment but to the original size. This ensures the reserved
region is completely removed when the caller calls 'lmb_free', as
this one takes the same size as passed to 'lmb_alloc' etc.

Add test to assert this.

5c38e05ed8 efi_loader: Make RTS relocation more robust
While changing the RTS alignment to 64KB in commit 7a82c3051c
("efi_loader: Align runtime section to 64kb") the relocation code
started to break.

The reason for that is that we didn't actually look at the real
relocation data. We merely took the RUNTIME_CODE section as a
hint and started to relocate based on self calculated data from
that point on. That calculation was now out of sync though.

To ensure we're not running into such a situation again, this patch
makes the runtime relocation code a bit more robust. We can just
trust the phys/virt hints from the payload. We also should check that
we really only have a single section, as the code doesn't handle
multiple code relocations yet.

Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
error:

lib/built-in.o: In function `fdtdec_get_pci_bar32':
lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'

This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
while SPL build does not descend into drivers/pci directory in
drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.

Fix this by applying appropriate #define guards in lib/fdtdec.c.
It looks like ns16550.c has the same problem, so fixed that too.

To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
(enables use of CONFIG_IS_ENABLED() macro).

be used before the I2C is initialized and only then the final dtb can be
selected.
To speed up the process and reduce memory usage, introduce a new function
fdtdec_setup_best_match() that re-use the DTBs loaded in memory by

49759743bf efi_loader: eliminate sandbox addresses
Do not use the sandbox's virtual address space for the internal structures

7b78d6438a efi_loader: Reserve unaccessible memory
On some systems, not all RAM may be usable within U-Boot. Maybe the
memory maps are incomplete, maybe it's used as workaround for broken
DMA. But whatever the reason may be, a platform can say that it does
not wish to have its RAM accessed above a certain address by defining
board_get_usable_ram_top().

In the efi_loader world, we ignored that hint, mostly because very few
boards actually have real restrictions around this.

So let's honor the board's wish to not access high addresses during
boot time. The best way to do so is by indicating the respective pages
as "allocated by firmware". That way, Operating Systems will still
use the pages after boot, but before boot no allocation will use them.

c2e1ad70a7 efi_loader: Ensure memory allocations are page aligned
When the max_addr parameter of efi_find_free_memory() is within bounds
of an existing map and fits the reservation, we just return that address
as allocation value.

That breaks however if max_addr is not page aligned. So ensure that it
always comes to us page aligned, simplifying the allocation logic.

Without this, I've seen breakage where we were allocating pages at -1U
(32bit) which fits into a region that spans beyond 0x100000000. In that
case, we would return 0xffffffff as a valid memory allocation, although
we usually do guarantee they are all page aligned.

Fix this by aligning the max address argument always.

afdc4fcc89 efi_loader: Handle RELA absolute relocations properly

21ebf2adde fdt_region: Ensure that depth never goes below -1
A specially crafted FIT image makes it possible to overflow the stack

variables on the heap and setting them to 0, e.g. disable signature
verification, thus bypassing it.

This change fixes a bug in fdt_find_regions where the fdt structure is

ef329a6a73 sysreset: Remove DM_FLAG_PRE_RELOC flag in various drivers
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

BootRom->ATF(BL2)->Optee(BL32)->u-boot(BL33)

In this case we need still to reserve the memory used by optee, to avoid
for example to realocate ourself to the same address at the end of DRAM.
So, we change here the dependencies on the OPTEE lib and we set the default
size and base of TZRAM to zero.

Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL

Currently we expect the loaded image handle to point to the loaded image
protocol. Additionally we have appended private fields to the protocol.

With the patch the handle points to a loaded image object and the private
fields are added here. This matches how we handle the net and the gop
object.

a353e6aa8e lib: strto: parse all lowercase metric prefixes in ustrtoul[l]
Both ustrtoul and ustrtoull interpret 1k but not 1m or 1g. Even if the
SI symbols for Mega and Giga are 'M' and 'G', certain entries of
eg. mtdparts also use (wrongly) the metric prefix 'm' and 'g'.

I do not see how parsing lowercase prefixes could break anything, so
parse them like their uppercase counterpart.

Also, even though kiB is not equal to kB in general, lets not change
U-Boot behavior and always use kiB and kB (same applies for MiB vs. MB
and GiB vs. GB) as a representation for 1024 instead of 1000.

dee37fc99d Remove <inttypes.h> includes and PRI* usages in printf() entirely
In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

f850371997 fdt: fix get_next_memory_node()
The get_next_memory_node() always sets mem to -1 , which is incorrect,
because then every iteration of memory bank parsing will start from the
first memory bank instead of the previous one.

On systems with 1 memory bank defined in DT and CONFIG_NR_DRAM_BANKS=4 ,
like ie. r8a77965-salvator-x , this will result in U-Boot incorrectly
reporting four identical memory banks with the same memory configuration.

Fix this by setting mem to startoffset value, which restores the behavior
before the fixed patch was applied.

e3332e1a1a Make kmalloc'ed memory really DMA-safe
In Linux, the memory returned by kmalloc() is DMA-capable.
However, it is not true in U-Boot.

At a glance, kmalloc() in U-Boot returns address aligned with
ARCH_DMA_MINALIGN.  However, it never pads the allocated memory.
This half-way house is completely useless because calling kmalloc()
and malloc() in this order causes a cache sharing problem.

Change the implementation to call malloc_cache_aligned(), which
allocates really DMA-capable memory.

9b89183b97 efi: Fix truncation of constant value
Starting with commit 867a6ac86d ("efi: Add start-up library code"),
sparse constantly complains about truncated constant value in efi.h:

include/efi.h:176:35: warning: cast truncates bits from constant value (8000000000000000 becomes 0)

This can get quite noisy, preventing real issues to be noticed:

$ make defconfig
*** Default configuration is based on 'sandbox_defconfig'
$ make C=2 -j12 2>&1 | grep truncates | wc -l
441

After the patch is applied:
$ make C=2 -j12 2>&1 | grep truncates | wc -l
0
$ sparse --version
v0.5.2

Following the suggestion of Heinrich Schuchardt, instead of only
fixing the root-cause, I replaced the whole enum of _SHIFT values
by ULL defines. This matches both the UEFI 2.7 spec and the Linux
kernel implementation.

Some ELF size comparison before and after the patch (gcc 7.3.0):

The commit 21b3edfc96 ("efi_loader: check parameters of CreateEvent")
enforces a strict parameter check at CreateEvent(). On the other hand,
UEFI specification version 2.7, section 7.1, says:

    The EVT_NOTIFY_WAIT and EVT_NOTIFY_SIGNAL flags are exclusive. If
    neither flag is specified, the caller does not require any notification
    concerning the event and the NotifyTpl, NotifyFunction, and
    NotifyContext parameters are ignored.

So the check should be mitigated so as to comply with the specification.
Without this patch, EDK2's Shell.efi won't be started.

282a06cbca efi_loader: Expose U-Boot addresses in memory map for sandbox
We currently expose host addresses in the EFI memory map. That can be
bad if we ever want to use sandbox to boot strap a real kernel, because
then the kernel would fetch its memory table from our host virtual address
map. But to make that use case work, we would need to have full control
over the address space the EFI application sees.

So let's expose only U-Boot addresses to the guest until we get to the
point of allocation. EFI's allocation functions are fun - they can take
U-Boot addresses as input values for hints and return host addresses as
allocation results through the same uint64_t * parameter. So we need to
be extra careful on what to pass in when.

With this patch I am successfully able to run the efi selftest suite as
well as grub.efi on aarch64.

Varargs differ between sysv and ms abi. On x86_64 we have to follow the ms
abi though, so we also need to make sure we use x86_64 varargs helpers.

This patch introduces generic efi vararg helpers that adhere to the
respective EFI ABI. That way we can deal with them properly from efi
loader code and properly interpret variable arguments.

This fixes the InstallMultipleProtocolInterfaces tests in the efi selftests

We try hard to make sure that SMBIOS tables live in the lower 32bit.
However, when we can not find any space at all there, we should not
error out but instead just fall back to map them in the full address

This can for example happen on systems that do not have any RAM mapped
in the lower 32bits of address space. In that case having any SMBIOS

The EFI image loader tries to determine which target architecture we're

So far this has worked based on CONFIG defines, because the target CPU
was always indicated by a config define. With sandbox however, this is
not longer true as all sandbox targets only encompass a single CONFIG
option and so we need to use compiler defines to determine the CPU
architecture.

I'm guessing the +2 here is for = and sep char. But there is another
totlen += 2; line that does that.

78a88f7930 doc: Replace DocBook with sphinx-based docs
The Linux kernel moved to sphinx-based documentation and got rid of the
DocBook based documentation quite a while ago. Hence, the DocBook
documentation for U-Boot should be converted as well.

To achieve this, import the necessary files from Linux v4.17, and
convert the current DocBook documentation (three files altogether) to
sphinx/reStructuredText.

For now, all old DocBook documentation was merged into a single
handbook, tentatively named "U-Boot Hacker Manual".

For some source files, the documentation style was changed to comply
with kernel-doc; no functional changes were applied.
