boot: pxe_utils: Add extension board devicetree overlay support
Add support for scanning and applying extension board devicetree
overlays during PXE boot. After loading the main board devicetree,
the system now scans for available extension boards and applies their
overlays automatically.
This enables dynamic hardware configuration for systems with extension
boards during boot scenarios which are using pxe_utils.

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.

SoCFPGA updates for v2025.10:
CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/27762
This pull request brings a set of updates across SoCFPGA platforms
covering Agilex5, Agilex7, N5X, and Stratix10. The changes include:
* Agilex5 enhancements:
- USB3.1 enablement and DWC3 host driver support
- System Manager register configuration for USB3
- Watchdog timeout increase and SDMMC clock API integration
- dcache handling improvements in SMC mailbox path
- Enable SPL_SYS_DCACHE_OFF in defconfig
* Clock driver improvements:
- Introduce dt-bindings header for Agilex clocks
- Add enable/disable API and EMAC clock selection fixes
- Replace manual shifts with FIELD_GET usage
* DDR updates:
- IOSSM mailbox compatibility check
- Correct DDR calibration status handling
* Device tree changes:
- Agilex5: disable cache allocation for reads
- Stratix10: add NAND IP node
- Enable driver model watchdog
- Enable USB3.1 node for Agilex5
* Config cleanups:
- 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.
