v2026.08.0

["Sascha Hauer" <s.hauer@pengutronix.de>]

Hi All,

I just released barebox-2026.08.0.

This release brings us a Kconfig/Kbuild update to Linux-6.18/6.17. Also
there we now have PCI based XHCI and SDHCI driver, primarily for use
with Qemu. One new board is supported, the Gira NCP Panel. Last not
least barebox now extlinux.conf which is a plain text configuration file
also used by U-Boot and syslinux to load kernel. initrd and device tree
from disk.

Other than that several other changes went into this release, see below
for a full list of patches.

Have Fun!
  Sascha

Migration notes for v2026.08.0
==============================

global.partitions.first_usable_lba removed
------------------------------------------

The ``global.partitions.first_usable_lba`` variable has been removed.
Use ``global.partitions.first_partition_offset`` instead.

The new variable is a byte offset used by free-space searches for new
partitions, for example ``parted mkpart_size``. The default is
``8388608`` bytes (8 MiB). To keep an old configuration, multiply the
old ``first_usable_lba`` value by 512.

ARCH=arm64
----------

Use of ``ARCH=arm`` for 64-bit ARM builds is deprecated and now emits
a warning. Users should change build scripts to use ``ARCH=arm64``
instead when targetting ARMv8.
