Merge patch series "Add support for secure falcon mode: load kernel image before args"
Anshul Dalal <anshuld@ti.com> says:
During the implementation of falcon mode for TI's K3 devices [1], I encountered
several limitations in regards to the current falcon mode support in U-Boot
especially in ensuring a secure boot flow.
Although the current implementation allows for loading of a signed fitImage as
the SPL payload, there are still a few edge cases that might allow bypassing the
verified boot path.
The following issues with current falcon mode need to be resolved:
1) No fallback:
We currently fallback to regular boot flow if falcon mode fails,
this might not be secure.
2) No arguments file:
We currently load a kernel file (which could be a raw image or FIT)
alongside an args file (usually the DT). The args file here doesn't have
any verification mechanism, so should be skipped altogether as the FIT can
contain the DT.
3) No access to env:
In ext and fat fs boot, currently we also reads the environment to get the
names of the kernel and the arg file. This should be disabled in secure
falcon flow as the env might not be secure.
4) No raw image boot:
Boot should fail when the kernel file is a raw kernel image, only FIT should
be allowed.
As per the recommendation of maintainers[2], I have decided to split the above
set of tasks into multiple patch series. This is the first one which fixes the
load order of kernel image and the args file in falcon mode. Along with some
minor cleanup.

spl: fat: load kernel image before args in falcon
Currently in falcon mode, the FS and raw mmc boot loads the args file
first followed by the kernel image whereas others load in the opposite
order. This inconsistency means falcon boot doesn't behave the same
across various boot media.
For example, in the case where the kernel file is a FIT with the kernel
image present alongside the dtb and the args file is another DT, which
DT should be picked? The one form the FIT or the one set by the args
file? Currently this depends entirely on how the boot media handles
falcon mode.
Therefore, this patch enforces the load order of the kernel image first
followed by the args file in FAT FS boot. So in the above example, the
args file would take precedence.

Revert "fdt: Make sure there is no stale initrd left"
This reverts commit
9fe2e4b46458f9c4ec6b8115ebf18b4b26fe6127.
Commit
9fe2e4b46458 ("fdt: Make sure there is no stale initrd left")
introduces a regression in case when U-Boot transfers control to an EFI
app which acts as a subsequent bootloading program. Such an app might
try to set "linux,initrd-start" and "linux,initrd-end" fdt properties,
but by that time those properties are already removed by the code added
in the mentioned commit.
Particularly, the issue was observed on the E850-96 board where GBL EFI
app [1] can't run Android successfully anymore. More specifically, the
kernel can't see the ramdisk and panics with next messages:
/dev/root: Can't open blockdev
VFS: Cannot open root device "" or unknown-block(0,0): error -6
Please append a correct "root=" boot option; ...
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
fdt_initrd() function (where initrd dts properties are removed) is
called two times:
1. First it's called by EFI boot manager (e.g. as a part of U-Boot
Standard Boot mechanism) when it's installing FDT:
fdt_initrd
image_setup_libfdt
efi_install_fdt
efi_bootmgr_run
efi_mgr_boot
It's already enough for EFI app to malfunction. But then it's also
called second time:
2. From the EFI app, via EFI DT fixup protocol:
fdt_initrd
image_setup_libfdt
efi_dt_fixup
struct efi_dt_fixup_protocol efi_dt_fixup_prot = {
.fixup = efi_dt_fixup
};
See [2] for specific GBL code which sets those fdt properties and then
runs DT fixup protocol callback.
This issue was discussed [3], but no action was taken since then. Revert
this patch for now, until a proper solution can be found.

env: spi: Fix gd->env_valid for the first write
When both SPI environment locations are invalid (gd->env_valid ==
ENV_INVALID), the first call to saveenv writes to the primary location and
sets the active flag. However, the logic for updating gd->env_valid
incorrectly sets it to ENV_REDUND, which does not match the actual location
written. This causes the first two writes to target the same location, and
alternation only begins after the second write.
Update the logic to alternate gd->env_valid based on whether the last write
was to the primary or redundant location, ensuring the first write sets
ENV_VALID and subsequent writes alternate as expected. This aligns
env_valid with the actual storage location and fixes the alternation
sequence from the first write.

- Simplify Agilex7 VAB defconfig
- Remove obsolete SYS_BOOTM_LEN from N5X VAB config
- Enable CRC32 support for SoCFPGA
- Increase USB hub debounce timeout
Overall this set improves reliability of DDR and cache flows,
adds missing USB and MMC features for Agilex5, and refines clock
and configuration handling across platforms.
This patch set has been tested on Agilex 5 devkit, and Agilex devkit.

When partition didn't exist, fb_nand_lookup returned 1, but
fastboot_nand_get_part_info passed it directly to getvar_get_part_info,

Add symlink from gpl-2.0.txt to a COPYING file
While it is good that the "Licenses/" directory contains the text
for all licenses that are applicable to u-boot code, it is harder
to determine at a glance what the default and/or preferred license
is. While humans can look at the Licenses/README file, this is not
machine parseable, making it tricky for license detection tools to
automatically determine/report on the overall / aggregate u-boot
license.
The project previously had a top level COPYING file containing a
short blurb, followed by the GPL license text. This was removed
back in commit
eca3aeb352c964bdb28b8e191d6326370245e03f when
the "Licenses/" directory was introduced. For the benefit of
automated tools, it is helpful to retain a top level COPYING
file in the repository. Rather than duplicate the license text,
however, a symlink from the Licenses/gpl-2.0.txt file should
suffice.

There are 3 options listed between choice/endchoice FILE/TEE/NO_STORE.
There is no reason to add other config with dependencies between

That's why move additional configuration with dependency below choice
