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.
With this change, the "Valid environment" printout correctly reflects the
active location after each save, and the alternation between primary and
redundant locations works as intended from the start.

documentation Documentation/arch/arm64/booting.rst:
x0 = physical address of device tree blob (dtb) in system RAM.
so kernel can replace U-Boot in FIP without modification of BL31.

Restore support for environment storage in EXT4 filesystem on eMMC boot.
The previous cleanup incorrectly removed this fallback option which is
needed for boards that store their environment in an EXT4 partition.
This configuration is OS-specific rather than board-dependent and should
remain as it is configurable via menuconfig. Even if it is not described
in ST defconfigs people may have enabled it in their defconfig.

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

doc: memory: fix encodings for spl layout diagrams
The commit
284ef1bbcefc ("doc: memory: Add documentation for system
RAM") added documentation for U-Boot's memory usage along with diagrams
showcasing the SPL's memory usage. Although the SVGs for the diagrams
were improperly encoded.
Therefore, this patch fixes the older SVGs with one's with better
encoding and reduced size created using inkscape[1].

vexpress64: Set the DM_RNG property
Enable the DM_RNG virtio random number generator driver in order to
consume entropy within U-Boot. This allows U-Boot to inject entropy to the
kernel via UEFI, so the kernel can use that early, for instance for
address layout randomisation, or when the kernel does not provide an
entropy driver itself.

bootstage: stash boot records to reserved mem before kernel handoff
U-Boot now stashes its bootstage buffer into a reserved memory region
whenever CONFIG_BOOTSTAGE_STASH is enabled, just before exiting to the
kernel. This allows a post boot parser to read a unified timeline
(SPL→U-Boot→Kernel→MCU/DSP) directly from DDR, enabling standardized
and repeatable boot-time profiling across releases and SoCs.
Change summary:
Call bootstage_stash_default() in announce_and_cleanup()
when CONFIG_BOOTSTAGE_STASH is set.
