a0abea867a clk: Add driver API to HTML docs
This converts the existing driver API docs (clk-uclass.h) to kernel doc
format and adds them to the HTML documentation. Because the kernel doc
sphinx converter does not handle functions in structs very well, the
individual methods are documented separately. This is primarily inspired by
the phylink documentation [1], which uses this trick extensively.

d9612f4426 tools: mkeficapsule: allow for specifying GUID explicitly
The existing options, "--fit" and "--raw," are only used to put a proper
GUID in a capsule header, where GUID identifies a particular FMP (Firmware
Management Protocol) driver which then would handle the firmware binary in
a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.

To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.
OLD:
   [--fit <image> | --raw <image>] <capsule file>
NEW:
   [--fit | --raw | --guid <guid-string>] <image> <capsule file>

2bc2f817ce board: toradex: add verdin imx8m plus support
This adds initial support for the Toradex Verdin iMX8M Plus Quad 4GB WB
IT V1.0B module. They are strapped to boot from eFuses which are factory
fused to properly boot from their on-module eMMC. U-Boot supports
booting from the on-module eMMC only, SDP support is disabled for now
due to missing i.MX 8M Plus USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet both on-module eQoS and FEC (requires PHY on carrier board)
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

a77f468099 introduce CONFIG_DEVICE_TREE_INCLUDES
The build system already automatically looks for and includes an
in-tree *-u-boot.dtsi when building the control .dtb. However, there
are some things that are awkward to maintain in such an in-tree file,
most notably the metadata associated to public keys used for verified
boot.

The only "official" API to get that metadata into the .dtb is via
mkimage, as a side effect of building an actual signed image. But
there are multiple problems with that. First of all, the final U-Boot
(be it U-Boot proper or an SPL) image is built based on a binary
image, the .dtb, and possibly some other binary artifacts. So
modifying the .dtb after the build requires the meta-buildsystem
(Yocto, buildroot, whatnot) to know about and repeat some of the steps
that are already known to and handled by U-Boot's build system,
resulting in needless duplication of code. It's also somewhat annoying
and inconsistent to have a .dtb file in the build folder which is not
generated by the command listed in the corresponding .cmd file (that
of course applies to any generated file).

So the contents of the /signature node really needs to be baked into
the .dtb file when it is first created, which means providing the
relevant data in the form of a .dtsi file. One could in theory put
that data into the *-u-boot.dtsi file, but it's more convenient to be
able to provide it externally: For example, when developing for a
customer, it's common to use a set of dummy keys for development,
while the consultants do not (and should not) have access to the
actual keys used in production. For such a setup, it's easier if the
keys used are chosen via the meta-buildsystem and the path(s) patched
in during the configure step. And of course, nothing prevents anybody
from having DEVICE_TREE_INCLUDES point at files maintained in git, or
for that matter from including the public key metadata in the
*-u-boot.dtsi directly and ignore this feature.

There are other uses for this, e.g. in combination with ENV_IMPORT_FDT
it can be used for providing the contents of the /config/environment
node, so I don't want to tie this exclusively to use for verified
boot.

c2969792c4 cmd: pxe_utils: sysboot: add label override support
This will allow consumers to choose a pxe label at runtime instead of
having to prompt the user. One good use-case for this, is choosing
whether or not to apply a dtbo depending on the hardware configuration.
e.g: for TI's AM335x EVM, it would be convenient to apply a particular
dtbo only when the J9 jumper is on PRUSS mode. To achieve this, the
pxe menu should have 2 labels, one with the dtbo and the other without,
then the "pxe_label_override" env variable should point to the label with
the dtbo at runtime only when the jumper is on PRUSS mode.

This change can be used for different use-cases and bring more
flexibilty to consumers who use sysboot/pxe_utils.

if "pxe_label_override" is set but does not exist in the pxe menu,
the code should fallback to the default label if given, and no failure
is returned but rather a warning message.

b05cebb5f2 imx8mq: Generate a single bootable flash.bin again
All i.MX8MQ boards have been converted to binman, which makes it
necessary to flash both flash.bin and u-boot.itb to get a bootable
system. Prior to the conversion, only flash.bin was needed.

Such new requirement breaks existing distro mechanisms to generate the
final binary because the extra u-boot.itb is now required.

Generate a final flash.bin that can be used again as a single bootable
binary to keep the original behavior.

After this change the SPL binary is called spl.bin, which is a more
descriptive name for its purpose, and can still be used standalone (for
example, for secure boot purposes).

Also update imx8mq_evk.rst to remove the u-boot.itb copy step.

This is a cherry-pick of 028abfd9b1 ("imx8mm-evk: Generate a single
bootable flash.bin again") adjusted to apply to i.MX8MQ.

d5b6e91ba2 bloblist: Support allocating the bloblist
Typically the bloblist is positioned at a fixed address in memory until
relocation. This is convenient when it is set up in SPL or before
relocation.

But for EFI we want to set it up only when U-Boot proper is running. Add
a way to allocate it using malloc() and update the documentation to cover
this aspect of bloblist.

Note there are no tests of this feature at present, nor any direct testing
of bloblist_init().

This can be added, e.g. by making this option controllable at runtime.

9819fe345c stm32mp1: ram: remove the support of calibration result
The support of a predefined DDR PHY tuning result is removed for
STM32MP1 driver because it is not needed at the supported frequency
when built-in calibration is executed.

The calibration parameters were provided in the device tree by the
optional node "st,phy-cal", activated in ddr helper file by the
compilation flag DDR_PHY_CAL_SKIP and filled with values generated
by the CubeMX DDR utilities.

This patch
- updates the binding file to remove "st,phy-cal" support
- updates the device trees and remove the associated defines
- simplifies the STM32MP1 DDR driver and remove the support of
  the optional parameter "st,phy-cal"

After this patch, the built-in calibration is always executed
and the calibration registers are moved in the phy dynamic part;
that allows manual tests.

To be clear, this changes the way that 'bootelf' and standalone boot
work. Before, if autostart was set to "fred" or "YES", for example, they
would consider that a "yes". This may change behaviour for some boards,
but the only in-tree boards which mention autostart use "no" to disable
it, which will still work.

86b9c3e4e4 env: Allow U-Boot scripts to be placed in a .env file
At present U-Boot environment variables, and thus scripts, are defined
by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text
to this file and dealing with quoting and newlines is harder than it
should be. It would be better if we could just type the script into a
text file and have it included by U-Boot.

Add a feature that brings in a .env file associated with the board
config, if present. To use it, create a file in a board/<vendor>
directory, typically called <board>.env and controlled by the
CONFIG_ENV_SOURCE_FILE option.

The environment variables should be of the form "var=value". Values can
extend to multiple lines. See the README under 'Environment Variables:'
for more information and an example.

In many cases environment variables need access to the U-Boot CONFIG
variables to select different options. Enable this so that the environment
scripts can be as useful as the ones currently in the board config files.
This uses the C preprocessor, means that comments can be included in the
environment using /* ... */

Also support += to allow variables to be appended to. This is needed when
using the preprocessor.

1834c081d3 efi: Add video support to the app
The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd

40dbf03d7d iommu: Add IOMMU uclass
This uclass is intended to manage IOMMUs on systems where the
IOMMUs are not in bypass mode by default.  In that case U-Boot
cannot ignore the IOMMUs if it wants to use devices that need
to do DMA and sit behind such an IOMMU.

This initial IOMMU uclass implementation does not implement and
device ops and is intended for IOMMUs that have a bypass mode
that does not require address translation.  Support for IOMMUs
that do require address translation is planned and device ops
will be defined when support for such IOMMUs will be added.

e7fb789612 sandbox: Remove OF_HOSTFILE
OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique and not causing any confusions,  we are better of having simpler
config options for the DTB.

So let's replace that with the existing OF_BOARD.  U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

028abfd9b1 imx8mm-evk: Generate a single bootable flash.bin again
After the conversion to binman in commit 8996e6b7c6 ("imx8mm_evk: switch
to use binman to pack images"), it is necessary to flash both flash.bin and
u-boot.itb to get a bootable system. Prior to this commit, only flash.bin
was needed.

Such new requirement breaks existing distro mechanisms to generate the
final binary because the extra u-boot.itb is now required.

Generate a final flash.bin that can be used again as a single
bootable binary to keep the original behavior.

After this change the SPL binary is called spl.bin, which is a more
descriptive name for its purpose, and can still be used standalone
(for example, for secure boot purposes).

Also update imx8mm_evk.rst to remove the u-boot.itb copy step.

  * N6311: SOM with i.MX6UL-2, 512MB RAM, 512MB SPI NAND

  * N6311-S: Baseboard with SOM N6311, eMMC, display (optional), ...
  * N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ...

Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config

a2db09e269 board: siemens: Add support for SIMATIC IOT2050 devices
This adds support for the IOT2050 Basic and Advanced devices. The Basic
used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS
quad-core version.

Both variants are booted via a Siemens-provided FSBL that runs on the R5
cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot
SPL, ATF and TEE have to reside in SPI flash.

Full integration into a bootable image can be found on
https://github.com/siemens/meta-iot2050

Based on original board support by Le Jin, Gao Nian and Chao Zeng.

77b11f7604 net: replace the "xfi" phy-mode with "10gbase-r"
As part of the effort of making U-Boot work with the same device tree as
Linux, there is an issue with the "xfi" phy-mode. To be precise, in
Linux there was a discussion (for those who have time to read:
https://lore.kernel.org/netdev/1576768881-24971-2-git-send-email-madalin.bucur@oss.nxp.com/)

which led to a patch:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=c114574ebfdf42f826776f717c8056a00fa94881

TL;DR: "xfi" was standardized in Linux as "10gbase-r".

This patch changes the relevant occurrences in U-Boot to use "10gbase-r"
instead of "xfi" wherever applicable.

b53bbca63b vexpress64: Add BASER_FVP vexpress board variant
The BASER_FVP board variant is implemented on top of the BASE_FVP board
config (which, in turn, is based on the Juno Versatile Express board
config). They all share a similar memory map - for BASER_FVP the map is
inverted from the BASE_FVP
(https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map)

 * Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same
   board config as BASE_FVP and JUNO
 * Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename
   to vexpress_aemv8.h)
 * Enable config to switch to EL1 for the BASER_FVP
 * Create vexpress_aemv8r defconfig
 * Provide an MPU memory map for the BASER_FVP

For now, only single core boot is supported.

documentation to reStructuredText at doc/board/ste/stemmy.rst and
make the device list complete. Also note that the board now boots
into USB Fastboot instead of just ending up at the U-Boot prompt.

The device table is mostly taken from the postmarketOS wiki article
(https://wiki.postmarketos.org/wiki/ST-Ericsson_NovaThor_U8500).
All the newly added devices were tested by Linus Walleij.

And note that we now also include the spdxcheck.py tool that
checkpatch.pl supports calling out to, and include upstream's
checkpatch.rst in our develop section of the documentation.

a2ac2b964b Convert CONFIG_SKIP_LOWLEVEL_INIT et al to Kconfig
This converts the following to Kconfig:
   CONFIG_SKIP_LOWLEVEL_INIT
   CONFIG_SKIP_LOWLEVEL_INIT_ONLY

In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.

2f45b3041e qfw: Switch to CONFIG_SYS_LOAD_ADDR from CONFIG_LOADADDR
All platforms define CONFIG_SYS_LOAD_ADDR, but only some define
CONFIG_LOADADDR.  Very very rarely are these not the same address, and
qemu-ppce500 is one such case.  However, based on reading the history of
the code, this mismatched value was simply a copy-paste from other
PowerPC platforms where it is this unused currently.  Switch the code to
use CONFIG_SYS_LOAD_ADDR and update the documentation.

2ac8490412 watchdog: add gpio watchdog driver
A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.

The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.

The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:

  https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/

If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.
