d64b9cdcd4 fdt: translate address if #size-cells = <0>
The __of_translate_address routine translates an address from the
device tree into a CPU physical address. A note in the description of
the routine explains that the crossing of any level with
since inherited from IBM. This does not happen for Texas Instruments, or
at least for the beaglebone device tree. Without this patch, in fact,
the translation into physical addresses of the registers contained in the
am33xx-clocks.dtsi nodes would not be possible. They all have a parent
with #size-cells = <0>.

The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation
possible even in the case of crossing levels with #size-cells = <0>.

The patch acts conservatively on address translation, except for
removing a check within the of_translate_one function in the
drivers/core/of_addr.c file:

+
        ranges = of_get_property(parent, rprop, &rlen);
-       if (ranges == NULL && !of_empty_ranges_quirk(parent)) {
-               debug("no ranges; cannot translate\n");
-               return 1;
-       }
        if (ranges == NULL || rlen == 0) {
                offset = of_read_number(addr, na);
                memset(addr, 0, pna * 4);
		debug("empty ranges; 1:1 translation\n");

There are two reasons:
1 The function of_empty_ranges_quirk always returns false, invalidating
  the following if statement in case of null ranges. Therefore one of
  the two checks is useless.

2 The implementation of the of_translate_one function found in the
  common/fdt_support.c file has removed this check while keeping the one
  about the 1:1 translation.

The patch adds a test and modifies a check for the correctness of an
address in the case of enabling translation also for zero size cells.
The added test checks translations of addresses generated by nodes of
a device tree similar to those you can find in the files am33xx.dtsi
and am33xx-clocks.dtsi for which the patch was created.

The patch was also tested on a beaglebone black board. The addresses
generated for the registers of the loaded drivers are those specified
by the AM335x reference manual.

2983ad55a1 clk: add clk_round_rate()
It returns the rate which will be set if you ask clk_set_rate() to set
that rate. It provides a way to query exactly what rate you'll get if
you call clk_set_rate() with that same argument.
So essentially, clk_round_rate() and clk_set_rate() are equivalent
except the former does not modify the clock hardware in any way.

ffa6602905 arm:pdu001: Use pseudo partition UUID for LINUX kernel boot paramter root
As more and more LINUX drivers are modified to use asynchronous probing
instead of synchronous probing, relying on device names being equal in
U-Boot and LINUX is not possible anymore. This is also true for block
device names like mmc0, mmc1 ect.
With LINUX kernel commit a1a4891 the probing type for the sdhci-omap
driver has been set to asynchronous mode too (probe_type is now
PROBE_PREFER_ASYNCHRONOUS).
In the case of the PDU001 board this results in the devices mmc0 and
mmc1 being swapped between U-Boot and LINUX. Device mmc0 in U-Boot
becomes mmc1 in LINUX an vice versa. Hence using device name identifiers
with LINUX kernel parameter root does not work anymore.
This patch changes the LINUX kernel boot parameter root to use the
pseudo (since we use MBR not GPT) partition UUID to locate the partition
hosting the root file system.

ba90472769 configs: am65x_evm: Define the maximum file size for DFU
In include/dfu.h, if CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then it is
defined as CONFIG_SYS_DFU_DATA_BUF_SIZE. This is 128 KiB for a53 core and
20 KiB for r5 core. If a larger file is transferred using dfu then it
fails.

CONFIG_SYS_DFU_DATA_BUF_SIZE can not be increased as there is not enough
heap memory to be allocated for the buffer in case of R5 spl.

Fix this by defining CONFIG_SYS_DFU_MAX_FILE_SIZE as the default
CONFIG_SYS_DFU_DATA_BUF_SIZE value.

0e4d5db4e0 sunxi: Add arm64 FEL support
So far we did not support the BootROM based FEL USB debug mode on the
64-bit builds for Allwinner SoCs: The BootROM is using AArch32, but the
SPL runs in AArch64.
Returning back to AArch32 was not working as expected, since the RMR
reset into 32-bit mode always starts execution in the BootROM, but not
in the FEL routine.

After some debug and research and with help via IRC, the CPU hotplug
mechanism emerged as a solution: If a certain R_CPUCFG register contains
some magic, the BootROM will immediately branch to an address stored in
some other register. This works well for our purposes.

Enable the FEL feature by providing early AArch32 code to first save the
FEL state, *before* initially entering AArch64.
If we eventually determine that we should return to FEL, we reset back
into AArch32, and use the CPU hotplug mechanism to run some small
AArch32 code snippet that restores the initially saved FEL state.

That allows the normal AArch64 SPL build to be loaded via the sunxi-fel
tool, with it returning into FEL mode, so that other payloads can be
transferred via FEL as well.

Tested on A64, H5 and H6.

6d295099cc tools: mkimage: Add Allwinner eGON support
So far we used the separate mksunxiboot tool for generating a bootable
image for Allwinner SPLs, probably just for historical reasons.

Use the mkimage framework to generate a so called eGON image the
Allwinner BROM expects.
The new image type is called "sunxi_egon", to differentiate it
from the (still to be implemented) secure boot TOC0 image.

20e442ab2d dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()
The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

38d6b7ebda spl: Drop bd_info in the data section
This uses up space in the SPL binary but it always starts as zero. Also
some boards cannot support data in TPL (e.g. Intel Apollo Lake).

Use malloc() to allocate this structure instead, by moving the init a
little later, after malloc() is inited. Make this function optional since
it pulls in malloc().

This reduces the TPL binary size on coral by about 64 bytes

cd53e5bf4b dm: core: Add a new sequence number for devices
At present each device has two sequence numbers, with 'req_seq' being
set up at bind time and 'seq' at probe time. The idea is that devices
can 'request' a sequence number and then the conflicts are resolved when
the device is probed.

This makes things complicated in a few cases, since we don't really know
what the sequence number will end up being. We want to honour the
bind-time requests if at all possible, but in fact the only source of
these at present is the devicetree aliases. Since we have the devicetree
available at bind time, we may as well just use it, in the hope that the
required processing will turn out to be useful later (i.e. the device
actually gets used).

Add a new 'sqq' member, the bind-time sequence number. It operates in
parallel to the old values for now. All devices get a valid sqq value,
i.e. it is never -1.

0b2fa98aa5 linker_lists: Fix alignment issue
The linker script uses alphabetic sorting to group the different linker
lists together. Each group has its own struct and potentially its own
alignment. But when the linker packs the structs together it cannot ensure
that a linker list starts on the expected alignment boundary.

For example, if the first list has a struct size of 8 and we place 3 of
them in the image, that means that the next struct will start at offset
0x18 from the start of the linker_list section. If the next struct has
a size of 16 then it will start at an 8-byte aligned offset, but not a
16-byte aligned offset.

With sandbox on x86_64, a reference to a linker list item using
ll_entry_get() can force alignment of that particular linker_list item,
if it is in the same file as the linker_list item is declared.

Consider this example, where struct driver is 0x80 bytes:

	ll_entry_declare(struct driver, fred, driver)

...

	void *p = ll_entry_get(struct driver, fred, driver)

If these two lines of code are in the same file, then the entry is forced
to be aligned at the 'struct driver' alignment, which is 16 bytes. If the
second line of code is in a different file, then no action is taken, since
the compiler cannot update the alignment of the linker_list item.

In the first case, an 8-byte 'fill' region is added:

 .u_boot_list_2_driver_2_testbus_drv
                0x0000000000270018       0x80 test/built-in.o
                0x0000000000270018                _u_boot_list_2_driver_2_testbus_drv
 .u_boot_list_2_driver_2_testfdt1_drv
                0x0000000000270098       0x80 test/built-in.o
                0x0000000000270098                _u_boot_list_2_driver_2_testfdt1_drv
 *fill*         0x0000000000270118        0x8
 .u_boot_list_2_driver_2_testfdt_drv
                0x0000000000270120       0x80 test/built-in.o
                0x0000000000270120                _u_boot_list_2_driver_2_testfdt_drv
 .u_boot_list_2_driver_2_testprobe_drv
                0x00000000002701a0       0x80 test/built-in.o
                0x00000000002701a0                _u_boot_list_2_driver_2_testprobe_drv

With this, the linker_list no-longer works since items after testfdt1_drv
are not at the expected address.

Ideally we would have a way to tell gcc not to align structs in this way.
It is not clear how we could do this, and in any case it would require us
to adjust every struct used by the linker_list feature.

One possible fix is to force each separate linker_list to start on the
largest possible boundary that can be required by the compiler. However
that does not seem to work on x86_64, which uses 16-byte alignment in this
case but needs 32-byte alignment.

So add a Kconfig option to handle this. Set the default value to 4 so
as to avoid changing platforms that don't need it.

Update the ll_entry_start() accordingly.

51bb33846a bootm: Support string substitution in bootargs
In some cases it is necessary to pass parameters to Linux so that it will
boot correctly. For example, the rootdev parameter is often used to
specify the root device. However the root device may change depending on
whence U-Boot loads the kernel. At present it is necessary to build up
the command line by adding device strings to it one by one.

It is often more convenient to provide a template for bootargs, with
U-Boot doing the substitution from other environment variables.

Add a way to substitute strings in the bootargs variable. This allows
things like "rootdev=${rootdev}" to be used in bootargs, with the
${rootdev} substitution providing the UUID of the root device.

For example, to substitute the GUID of the kernel partition:

  setenv bootargs "console=/dev/ttyS0 rootdev=${uuid}/PARTNROFF=1
		kern_guid=${uuid}"
  part uuid mmc 2:2 uuid
  bootm

This is particularly useful when the command line from another place. For
example, Chrome OS stores the command line next to the kernel itself. It
depends on the kernel version being used as well as the hardware features,
so it is extremely difficult to devise a U-Boot script that works on all
boards and kernel versions. With this feature, the command line can be
read from disk and used directly, with a few substitutions set up.

96434a76fd env: Allow returning errors from hdelete_r()
At present this function returns 1 on success and 0 on failure. But in
the latter case it provides no indication of what went wrong.

If an attempt is made to delete a non-existent variable, the caller may
want to ignore this error. This happens when setting a non-existent
variable to "", for example.

Update the function to return 0 on success and a useful error code on
failure. Add a function comment too.

Make sure that env_set() does not return an error if it is deleting a
variable that doesn't exist. We could update env_set() to return useful
error numbers also, but that is beyond the scope of this change.

fe669925cb arm: tegra: add options for BOOTENV_EFI_SET_FDTFILE_FALLBACK for tegra186
Upstream linux DT naming doesn't align with the U-Boot DT, which may
not always be the case so this allows using BOOTENV_EFI_SET_FDTFILE_FALLBACK
where it might be appropriate for some boards.

632fb978a5 arm: tegra: define fdtfile option for distro boot
For booting via UEFI we need to define the fdtfile option so
bootefi has the option to load a fdtfile from disk. For arm64
the kernel dtb is located in a vendor directory so we define
that as nvidia for that architecture.

bb7e71d33c efi_loader: add firmware management protocol for raw image
In this commit, a very simple firmware management protocol driver
is implemented. It will take a binary image in a capsule file and
apply the data using dfu backend storage drivers via dfu_write_by_alt()
interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

f27c201485 efi_loader: add firmware management protocol for FIT image
In this commit, a very simple firmware management protocol driver
is implemented. It will take a common FIT image firmware in a capsule
file and apply the data using dfu backend storage drivers via
update_fit() interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

Fit image is a common file format for firmware update on U-Boot, and
this protocol works neatly just as a wrapper for one.

8d99026f06 efi_loader: capsule: support firmware update
A capsule tagged with the guid, EFI_FIRMWARE_MANAGEMENT_CAPSULE_ID_GUID,
is handled as a firmware update object.
What efi_update_capsule() basically does is to load any firmware management
protocol (or fmp) drivers contained in a capsule, find out an appropriate
fmp driver and then invoke its set_image() interface against each binary
in a capsule.
In this commit, however, loading drivers is not supported.

The result of applying a capsule is set to be stored in "CapsuleXXXX"
variable, but its implementation is deferred to a fmp driver.

ed9349c697 efi_loader: capsule: add memory range capsule definitions
Memory range capsule gives us a way to notify that some memory regions
should be left untouched across the next reset.
See UEFI specification, section 8.5.3.

Since how we should handle this kind of capsule is totally up to
the system, no implementation will be added in this commit.

c74cd8bd08 efi_loader: capsule: add capsule_on_disk support
Capsule data can be loaded into the system either via UpdateCapsule
runtime service or files on a file system (of boot device).
The latter case is called "capsules on disk", and actual updates will
take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and
all the capsule files to be executed will be detected only if they
are located in a specific directory, \EFI\UpdateCapsule, on a device
that is identified as a boot device by "BootXXXX" variables.

c8d0fd5825 efi_loader: Introduce eventlog support for TCG2_PROTOCOL
In the previous patches we only introduced a minimal subset of the
EFI_TCG2_PROTOCOL protocol implementing GetCapability().
So let's continue adding features to it, introducing the
GetEventLog() and HashLogExtendEvent() functions.

In order to do that we first need to construct the eventlog in memory,
specifically in EFI_BOOT_SERVICES_DATA memory and a configuration table
from EFI_ACPI_MEMORY_NVS.
U-Boot won't currently add any events to the log or measure any
components, but will expose the necessary EFI APIs for applications
to do so.

The current tpm2_pcr_extend is hardcoded using SHA256.
Let's make the actual command to the TPM2 configurable so we can support
a wider range of algorithms and keep the current command line as-is i.e
limited to SHA256 only
