272b8784fa fit: Rework SPL_LOAD_FIT_ADDRESS slightly
Options which deal with memory locations and have a default value of 0x0
are dangerous, as that is often not a valid memory location. Rework
SPL_LOAD_FIT_ADDRESS as follows:
- Add SPL_HAS_LOAD_FIT_ADDRESS to guard prompting the question as the
  case of loading a FIT image does not strictly require setting an
  address and allows for a malloc()'d area to be used.
- For SPL_RAM_SUPPORT, select the new guard symbol if SPL_LOAD_FIT is
  enabled because in that case an address must be provided.
- Update defconfigs for these new changes. Largely this means some
  defconfigs need to enable SPL_HAS_LOAD_FIT_ADDRESS to maintain their
  current status. In the case of sandbox, we also need to set
  SPL_LOAD_FIT_ADDRESS to 0x0.

1cd0a44106 boot: fix missing dependency for BOOTMETH_ANDROID
The code depends on set_avendor_bootimg_addr and set_abootimg_addr
functions which are only defined in cmd/abootimg.c, only built when
CMD_ABOOTIMG=y so let's add a dependency.

It should be "depends on" to be properly implemented, but we get a
circular dependency otherwise:
boot/Kconfig:566:error: recursive dependency detected!
boot/Kconfig:566:	symbol BOOTMETH_ANDROID depends on CMD_ABOOTIMG
cmd/Kconfig:504:	symbol CMD_ABOOTIMG depends on ANDROID_BOOT_IMAGE
boot/Kconfig:7:	symbol ANDROID_BOOT_IMAGE is selected by BOOTMETH_ANDROID

so instead we do a select. It is safe because CMD_ABOOTIMG depends on
ANDROID_BOOT_IMAGE which we select here as well.

e22335a221 rockchip: Add support for RAM boot from maskrom mode
The BootROM in Rockchip SoCs will enter maskrom mode when boot firmware
cannot be found in nand/spi/mmc storage.

In maskrom mode the USB OTG port can accept one of two custom commands.

Initially a 0x471 command to load TPL into SRAM. After TPL has been
executed and it has returned back-to-BROM, a 0x472 command to load SPL
into start of DRAM.

Add two binman images that can be used to RAM boot from maskrom mode:
- u-boot-rockchip-usb471.bin that contains TPL to init DRAM.
- u-boot-rockchip-usb472.bin that contains SPL and the normal FIT
  payload with i.e. U-Boot proper, TF-A and FDT.

A config fragment rockchip-ramboot.config can be used to enable building
of these two binman images, e.g.:

  make generic-rk3588_defconfig rockchip-ramboot.config

These binman images can be used with the proprietary rkbin boot_merger
tool to create a special loader image that can be used with tools such
as rkdeveloptool or rockusb tools to RAM boot from maskrom, e.g.:

  Create loader image:
    $ ../rkbin/tools/boot_merger ./RK3588MINIALL.ini

  Boot from maskrom:
    $ rkdeveloptool db u-boot-rockchip-rk3588-loader.bin
   or
    $ rockusb download-boot u-boot-rockchip-rk3588-loader.bin

Another option that does not require use of proprietary tools is using
open source tools such as rkflashtool or rkusbboot that can load the
binman images directly without any need to first create a special loader
image to RAM boot from maskrom, e.g.:

  $ rkflashtool l < u-boot-rockchip-usb471.bin
  $ rkflashtool L < u-boot-rockchip-usb472.bin
 or
  $ rkusbboot u-boot-rockchip-usb471.bin u-boot-rockchip-usb472.bin

62e89de769 Merge patch series "rsa: fix dependency, rename and relocate RSASSA PSS symbols"
Quentin Schulz <foss+uboot@0leil.net> says:

While historically signature verification is mostly done for FIT such
FIT_SIGNATURE dependency for signature algorithm makes sense, it isn't
the only kind of file we can verify signatures of. It can also be done
manually with rsa_verify_hash() with an embedded public key.

Considering the impacted code is guarded by RSA_VERIFY, let's make the
symbol depend on that otherwise selecting it without RSA_VERIFY won't do
anything. The FIT_SIGNATURE dependency wasn't also enough before as it
only implied RSA_VERIFY.

Then, simply relocate the RSA SSA PSS padding with the other RSA symbols
in lib/rsa instead of in boot/ and rename it to remove the mention to
FIT.

Finally, add the PSS padding wherever PKCS1.5 padding is specified as
one or the other can be used.

360dd89b36 rsa: rename FIT_RSASSA_PSS to RSASSA_PSS and move symbols under lib/rsa
This renames FIT_RSASSA_PSS symbols to drop the FIT_ prefix to avoid
potential confusion since there's nothing FIT specific to those symbols.

It also isn't really related to booting, so boot/Kconfig is an odd place
for them to live. Since they make sense only in relation with RSA,
simply move them to lib/rsa where it makes more sense for them to
reside.

63686bf6e0 boot: fix incorrect dependency of FIT_RSASSA_PSS
This padding has nothing to do with FIT except that we can make use of
it when verifying the FIT signatures.

This padding can also be used to verify the signature "manually" e.g. by
calling rsa_verify_hash() directly with an embedded public key.

Additionally, this padding is only useful if RSA (and specifically
RSA_VERIFY) is enabled otherwise it's not used.
The only other place it's used is in rsa-sign.c which is only built for
the host tools and handled by TOOLS_FIT_RSASSA_PSS symbol instead, so no
need to care for that one.

Finally, the FIT_SIGNATURE dependency also wasn't enough because it only
implies RSA_VERIFY, meaning it can be disabled and still have
FIT_RSASSA_PSS enabled.

So add a dependency on RSA_VERIFY and reword the input prompt.

28b81c07be Merge patch series "Remove usage of CMD_BOOTx from SPL code"
Anshul Dalal <anshuld@ti.com> says:

Hi all,

We currently make use of CMD_BOOTI and CMD_BOOTZ in the SPL boot flow in
falcon mode, this isn't correct since all CMD_* configs are only meant
for U-Boot proper and not the SPL.

Therefore this patch set adds new LIB_BOOT[IMZ] configs that allow for
more granular selection of their respective compilation targets.

Additionally, this also allows us to more easily disable support for
raw images from secure falcon mode (SPL_OS_BOOT_SECURE) by doing the
following:

  config LIB_SPL_BOOTI
    ...
    depends on SPL_OS_BOOT && !SPL_OS_BOOT_SECURE
    ...

823e453987 spl: remove usage of CMD_BOOTx from image parsing
Using CMD_* configs from spl doesn't make logical sense. Therefore
this patch replaces the checks for CMD_BOOTx with newly added library
symbols LIB_BOOT[IMZ] and SPL_LIB_BOOT[IMZ] which are enabled by their
respective CMD_* or SPL_* counterparts.

On platforms with non-secure falcon mode, SPL_BOOTZ is enabled by
default for 32-bit ARM systems and SPL_BOOTI is enabled by default for
64-bit ARM and RISCV.

The respective C files (image.c/zimage.c) are compiled based on library
symbols $(PHASE_)LIB_BOOTx instead which are in turn selected by both
CMD_BOOTx and SPL_BOOTx as required.

up to 125°C), this series implements necessary changes within TI K3 AM62P and

Rename the environment related variables and add ENV_ prefix, so that
all configuration options which are related to environment would have
an CONFIG_ENV_ prefix. No functional change.

009d7722ff Merge patch series "bootstd: New bootmeth for RAUC A/B systems"
Martin Schwan <m.schwan@phytec.de> says:

This series implements a new bootmeth for RAUC A/B systems. RAUC (Robust
Auto Update Controller) is a lightweight update client, providing "Safe
and Secure OTA Updates for Embedded Linux". See the following links for
more information about RAUC:

  https://rauc.io/
  https://rauc.readthedocs.io/en/latest/

PHYTEC uses RAUC in its Yocto based distribution "Ampliphy" as the
default way of updating embedded devices based on PHYTEC hardware. So
far, the logic selecting the correct partitions and files to boot was
being implemented in the U-Boot environment. While this is a
straightforward way to do it, adding and supporting new platforms became
somewhat tedious and is platform-specific. The introduction of U-Boot's
"Standard Boot" provided a convincing alternative, promising a simpler
and more portable way of booting, even for RAUC systems. This led me to
implement a new bootmeth supporting RAUC A/B systems. Note, that this
new bootmeth is not proprietary to PHYTEC products and is designed to
work on other hardware with a RAUC A/B system, too.

The bootmeth currently only supports symmetric A/B partitioning layouts.
E.g. A/rescue is not (yet) supported. The partition indexes and default
slot tries can be specified via configuration options.

For now, the bootmeth_rauc uses a similar approach for loading the
Kernel and device tree as the bootmeth_script, in that it requires a FIT
containing a U-Boot script loading the desired distro. It could be
possible to support booting without a script and load the Kernel and DT
directly with this bootmeth, but I found the script method to be very
flexible for now, in letting the distro decide what to load.

The bootmeth_rauc was tested on a phyBOARD-Pollux i.MX8M Plus [1] with
BSP-Yocto-Ampliphy-i.MX8MP-PD24.1.2 [2].

Supported boot devices are currently only MMC devices, but it should be
possible to add SPI flashes in the future.

To test this patch stack with PHYTEC's phyBOARD-Pollux i.MX8M Plus
board, you need to adjust the boot files to include the boot.scr.uimg
containing the distro's boot script and set "optargs" to "${raucargs}"
in it. Also disable any legacyboot in the U-Boot environment and simply
boot with Standard Boot:

  bootmeth order rauc
  bootflow scan -lb

3b6760ddeb bootstd: Rework BLK dependency
The bootstd code itself does not have any dependency on BLK in order to
build. However, in order to minimize size growth of non-migrated
platforms, change this from being "default y" to "default y if BLK".
This will make it easier to begin migration of platforms which do not
have any BLK-class device but do want to use bootstd.

c054642672 boot: let BOOTSTAGE_RECORD_COUNT default to 50
BOOTSTAGE_RECORD_COUNT=30 is too small to record booting a FIT image
with EFI kernel, initrd, dtb as seen on the StarFive VisionFive 2
board.

Increase the default for BOOTSTAGE_RECORD_COUNT to 50.

f1eb367d76 vbe: Add an implementation of VBE-ABrec
So far only VBE-simple is implemented in U-Boot. This supports a single
image which can be updated in situ.

It is often necessary to support two images (A and B) so that the board
is not bricked if the update is interrupted or is bad.

In some cases, a non-updatable recovery image is desirable, so that the
board can be returned to a known-good state in the event of a serious
failure.

Introduce ABrec which provides these features. It supports three
independent images and the logic to select the desired one on boot.

While we are here, fix a debug message to indicate the function it
called. Provide a maintainers entry for VBE.

Note that fwupdated only supports VBE-simple so far, but supports for
ABrec will appear in time.
