f1b20acb4a hashtable: Fix length calculation in hexport_r
The length returned by hexport_r has a few redundant characters.
This appears as NULL characters at the end so seems harmless.

Remove the surplus counts in two places

totlen += strlen(ep->key) + 2;
I'm guessing the +2 here is for = and sep char. But there is another
totlen += 2; line that does that.

size = totletn + 1;
Doesn't make sense and isn't justified with any comment.

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.

d9fc9077eb hashtable: do not recreate whole hash table if vars are passed to himport_r
When vars are passed to the himport_r function with H_NOCLEAR flag,
those vars will be overridden in the current environment and if one of
those vars is not in the imported environment, it'll be deleted in the
current environment whatever the flag passed to himport_r.

The H_NOCLEAR flag is used to clear the whole environment whether vars
are passed to the function or not.

This leads to incoherent behaviour. If one passes vars to himport_r
with the H_NOCLEAR flag, if a var in vars is not in the imported env,
that var will be removed from the current env.

If one passes vars to himport_r without the H_NOCLEAR flag, the whole
environment will be removed and vars will be imported from the
environment in RAM.

It makes more sense to keep the variable that is in the current
environment but not in the imported environment if the H_NOCLEAR flag is
set and remove only that variable if the H_NOCLEAR flag is not set.

Let's clear the whole environment only if H_NOCLEAR and vars are not
passed to himport_r.

Let's remove variables that are in the current environment but not in
the imported env only if the H_NOCLEAR flag is not passed.

0186644646 efi.h: Do not use config options
Currently efi.h determines a few bits of its environment according to
config options. This falls apart with the efi stub support which may
result in efi.h getting pulled into the stub as well as real U-Boot
code. In that case, one may be 32bit while the other one is 64bit.

This patch changes the conditionals to use compiler provided defines
instead. That way we always adhere to the build environment we're in
and the definitions adjust automatically.

9f0b0113c9 x86: use EFI calling convention for efi_main on x86_64
UEFI specifies the calling convention used in Microsoft compilers;
first arguments of a function are passed in (%rcx, %rdx, %r8, %r9).

All other compilers use System V ABI by default, passing first integer
arguments of a function in (%rdi, %rsi, %rdx, %rcx, %r8, %r9).

These ABI also specify different sets of registers that must be preserved
across function calls (callee-saved).

GCC allows using the Microsoft calling convention by adding the ms_abi
attribute to a function declaration.

Current EFI implementation in U-Boot specifies EFIAPI for efi_main()
in the test apps but uses default calling convention in lib/efi.

Save efi_main() arguments in the startup code on x86_64;
use EFI calling convention for _relocate() on x86_64;
consistently use EFI calling convention for efi_main() everywhere.

There are no changes in this commit but a new organization of the code
as follow.

* cmd/ directory:
        > move existing code from cmd/tpm.c in cmd/tpm-common.c
	> move specific code in cmd/tpm-v1.c
	> create a specific header file with generic definitions for

* lib/ directory:
        > move existing code from lib/tpm.c in lib/tpm-common.c
	> move specific code in lib/tpm-v1.c
	> create a specific header file with generic definitions for
	  the library itself called lib/tpm-utils.h

* include/ directory:
        > move existing code from include/tpm.h in include/tpm-common.h
	> move specific code in include/tpm-v1.h

Code designated as 'common' is compiled if TPM are used. Code designated
as 'specific' is compiled only if the right specification has been
selected.

All files include tpm-common.h.
Files in cmd/ include tpm-user-utils.h.
Files in lib/ include tpm-utils.h.
Depending on the specification, files may include either (not both)
tpm-v1.h or tpm-v2.h.

9f9ce3c369 tpm: prepare introduction of TPMv2.x support in Kconfig
Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.

Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.

The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.

Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

f9cfad1a61 efi_loader: Fix network DP with DM_ETH
When CONFIG_DM_ETH is set, we assemble the device path properly with a
full device hierarchy. Our helper function dp_fill() even put the MAC
node itself in it for us.

However, for non-DM compatibility we also have code in that added the
MAC node manually. That code now runs on top of the existing MAC node:

  Handle 0x3db2f6b0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /MacAddr(b8:27:eb:e1:81:47,57)/EndEntire

We obviously don't need the additional node and in fact, grub chokes on
it and fails to match the DP against the ethernet device node. So this
patch moves the additional MAC node into the non-DM code path:

  Handle 0x3db3fde0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /EndEntire

While at it, we also mark the non-DM MAC node as ethernet.

The unit test checks if a device tree is installed. It requires that the
'compatible' property of the root node exists. If available it prints the
'serial-number' property.

The serial-number property is derived from the environment variable
'serial#'. This can be used to check if the image_setup_libfdt() function
is executed.

A Python test is supplied. It sets a value for serial# and checks that the
selftest shows this as serial-number.

We need to pull this value out of u-boot in order to produce an IMX IVT/CSF

have CONFIG_OPTEE_LOAD_ADDR appear in u-boot.cfg.

image subsystem constants and use it in our assembler code.

IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification

When printing '%pD' with a value of NULL we want to output
'<NULL>'. But this requires copying to buf. Leave this
to string16.

A unit test is supplied which relies on EFI support in the sandbox.

The development for EFI support in the sandbox is currently in branch
u-boot-dm/efi-working. The branch lacks commit 6ea8b580f0 ("efi_loader:
correct DeviceNodeToText for media types"). Ater rebasing the aforementioned

c6fa5df6aa efi_loader: Always use EFIAPI instead of asmlinkage
EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.

On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.

So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.

While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

6698bb343f efi: Conflict efi_loader with different stub bitness
We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.

The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.

This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

05ef48a248 efi_driver: EFI block driver
This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices

For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol

The uclass provides the bind, start, and stop entry points for the driver
binding protocol.

In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.

The EFI block driver binds to controllers implementing the block io
protocol.

When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.

The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.

A usage example is as following:

U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.

Now the EFI block driver installs the partitions with the simple file
protocol.

iPXE uses the simple file protocol to load Grub or the Linux Kernel.

905cb9e172 efi_loader: Ensure efi_dp_find_obj() finds exact matches
When calling efi_dp_find_obj(), we usually want to find the *exact* match
of an object for a given device path. However, I ran into a nasty corner case
where I had the following objects with paths available:

Handle 0x9feffa70
  /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire
Handle 0x9feffb58
  /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire

and was searching for

  /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire

But because our device path search looked for any substring match, it would
return

  /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire

because that path is a full substring of the path we were searching for.

So this patch adapts the device path search logic to always look for exact
matches first. The way we distinguish between those cases is by looking at
whether our caller actually deals with remainders.

As a side effect, the code as is from all I can tell now never does a
substring match anymore, because it always gets called with rem=NULL, so
we always only do exact matches now.

ae67dca5e6 efi_loader: helloworld.c: Explicitly use .rodata for loaded_image_guid
Commit bbf75dd934 ("efi_loader: output load options in helloworld")
introduced a const variable in efi_main() called loaded_image_guid which
got populated from a constant struct.

While you would usually expect a compiler to realize that this variable
should really just be a global pointer to .rodata, gcc disagrees and instead
puts it on the stack. Unfortunately in some implementations of gcc it does
so my calling memcpy() which we do not implement in our hello world
environment.

So let's explicitly move it to a global variable which in turn puts it in
.rodata reliably and gets rid of the memcpy().

Depending on your compiler, when compiling the hello world efi binary
with -Os, gcc might think it's a smart idea to replace common patterns
such as memory copies with explicit calls to memcpy().

While that sounds great at first, we don't have any memcpy() available
in our helloworld build target. So let's indicate to gcc that we really
do want to have the code be built as freestanding.

c034b7fd41 efi_loader: Fix partition offsets
Commit 884bcf6f65 (efi_loader: use proper device-paths for partitions) tried
to introduce the el torito scheme to all partition table types: Spawn
individual disk objects for each partition on a disk.

Unfortunately, that code ended up creating partitions with offset=0 which meant
that anyone accessing these objects gets data from the raw block device instead
of the partition.

Furthermore, all the el torito logic to spawn devices for partitions was
duplicated. So let's merge the two code paths and give partition disk objects
good offsets to work from, so that payloads can actually make use of them.

b6e9e09770 efi_loader: initialise partition_signature memory
Zero partition_signature in the efi_device_path_hard_drive_path
structure when signature_type is 0 (no signature) as required by the
UEFI specification.

This is required so that efi_dp_match() will work as expected
when doing memcmp() comparisons.  Previously uninitialised memory
would cause it not match nodes when it should have when the signature
type was not GUID.

Corrects a problem where the loaded image protocol would not return a
device path with MEDIA_DEVICE causing the OpenBSD bootloader to fail
on rpi_3 and other targets.

v2: Also handle signature_type 1 (MBR) as described in the specification

Building spl with CONFIG_OF_EMBED enabled results in an error message
on my board: "SPL image too big". This is because the fdtgrep build
step is only executed for CONFIG_OF_SEPARATE.

Fix this by moving the fdtgrep build step ('cmd_fdtgreo') from
scripts/Makefile.spl to dts/Makefile so that the reduced dtb is
available for all kinds of spl builds.

The resulting variable name for the embedded device tree blob changes,
too, which is why common.h and fdtdec.c have tiny changes.

patch extends the function such that if a particular /memory node does
no longer have further "reg" entries and CONFIG_NR_DRAM_BANKS still
allows for more DRAM banks, the code moves on to the next memory node
and checks it's "reg"s. This makes it possible to handle both systems
with single memory node with multiple entries and systems with multiple
memory nodes with single entry.

15b97f5c5e pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile
The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

  lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
  lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

405835645a efi_loader: Disable env_save() call on boot
With the introduction of EFI variable support, we also wanted to persist
these EFI variables. However, the way it was implemented we ended up
persisting all U-Boot environment variables on every EFI boot.

That could potentially lead to unexpected side effects because variables
that were not supposed to be written to persisted env get written. It also
means we may end up writing the environment more often than we should.

For this release, let's just disable EFI variable persistence and instead
implement it properly for the next one.

2d5dc2a52d efi_loader: console support for color attributes
Shell.efi uses this, and supporting color attributes makes things look
nicer.  Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".

Search for up to MAX_SEARCH_PARTITIONS matching the other callers of

This allows OpenBSD to boot via the efi_loader on rpi_3 again after
changes made after U-Boot 2017.09.  With MBR partitioning OpenBSD will
by default use the fourth partition for the 0xA6 (OpenBSD) partition.
