Add hashes for the Xilinx vendor repo xilinx_v2026.1 release tag.
Create a new sub-dir including the version name because the legal-info hashes
change between versions for linux and the arm-trusted-firmware. This way, any
time there is a version bump, the new version hashes can be added before the
old version hashes are removed and the legal-info can always be verified.

- Bump u-boot to version 2026.04.
smhload command has been removed from u-boot 2022.07 [1], use
"load hostfs" generic command as suggested by the documentation [2].
This commit adds BR2_TARGET_UBOOT_NEEDS_DTC=y, because the new
2026.04 version does need dtc. Adding host-dtc also avoid uboot build
failures on hosts with libyaml (uboot builds its own dtc if none is
defined in DTC build variable).
This commit also removes BR2_TOOLCHAIN_BUILDROOT_CXX=y, which was
forgotten when the defconfig was switched to Bootlin toolchain, in
commit [3].

UEFI platforms with a Devicetree have recently gained support for some form
of network booting. [1][2]
On those platforms, the UEFI firmware downloads the disk image over the
network and presents it to UEFI applications using the simple filesystem
protocol. This is sufficient for OS loaders such as e.g. GRUB to find their
configuration and load the kernel image.
The firmware must also describe the ramdisk to the OS, so that it finds its
root filesystem. On ACPI based platforms this is done with an NVDIMM
Firmware Interface Table (NFIT). On Devicetree based platforms, this can be
done with a pmem node. [3]
Add a kernel config fragment to add pmem support, which enables network
boot on UEFI platforms with Devicetree.
Also, briefly mention that we support this scenario in the readme.
This can be tested on Qemu, with the following procedure:
Build aarch64_efi_defconfig in a folder, to obtain output/images/disk.img,
and serve the image over HTTP with python:
$ python -m http.server -d output/images/
In another terminal and another folder, configure a U-Boot based firmware
starting from qemu_aarch64_ebbr_defconfig, and with the following
additional configurations:
BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2026.04"
BR2_TARGET_UBOOT_NEEDS_DTC=y
Add the following U-Boot configurations to
board/qemu/aarch64-ebbr/u-boot.fragment:
CONFIG_EFI_HTTP_BOOT=y
CONFIG_NET_LWIP=y
Build everything; you should obtain output/images/flash.bin.
Start Qemu as per board/qemu/aarch64-ebbr/readme.txt, but omitting the hd0
-device and -drive stanzas.
U-Boot should start; interrupt it with enter.
At U-Boot prompt, type the following commands:
=> setenv loadaddr 0x43000000
=> efidebug boot rm 0
=> efidebug boot add -u 0 net http://10.0.2.2:8000/disk.img
=> efidebug boot order 0
=> bootefi bootmgr
U-Boot should download the disk image over HTTP and boot Linux with UEFI.
Look for the following message in Linux boot log, to confirm that it did
indeed mount its rootfs from the downloaded image:
EXT4-fs (pmem0p2): mounted filesystem ...

- updates the Kernel from LTS 6.6.14 to 6.18.16
- updates U-Boot from 2024.01 to 2026.04
- switches to Bootlin external glibc stable toolchain
- enable BR2_DOWNLOAD_FORCE_CHECK_HASHES=y, add custom hashes stored
in BR2_GLOBAL_PATCH_DIR="board/ti/am574x-idk/patches" and removes
the exception entry in .checkpackageignore.
- enable BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME=y to install the board
devicetree in the boot (vfat) partition keeping the directory
prefixes (ti/omap/am574x-idk.dtb). u-boot nowadays is looking for
boards devicetree using such directory prefixes [1].
Update genimange.cfg file accordingly.
- While at it, add a label to the boot (vfat) partition to not use a
generated label.
- set BR2_TARGET_ROOTFS_EXT2_SIZE="256M" since the rootfs no longer
fit in the default size (60M).
- Remove the rootfs partition predefined 1G size to avoid a parted
warning about "unallocated space within the partition."
- Update extlinux.conf kernel command line to use "console=ttyS2"
instead of "ttyS0". Seems a typo introduced with the defconfig
(AM57xx always used ttyS2 as kernel console).
