To verify only Kconfig/Makefile is touched:
git show --numstat --format=oneline HEAD | grep -v 'Kconfig\|Makefile'
will print only arch/powerpc/Kbuild.
To verify nothing unexpected is added:
git show -U0 | grep '^-[^-]\|^+[^+]' | sort -u

Current qemu-virt64 barebox support doesn't look much like what's
offered on physical boards. It's not relocatable, lacks PBL and
doesn't use device tree. As qemu-system-aarch64 -M virt -kernel
already supplies an external device tree, we could just replace
all existing support with BOARD_ARM_GENERIC_DT, which builds a
barebox image that reuses an externally passed device tree.
The 32-bit ARM VIRT support has some board code for host name
setting and overlay applying to handle environment and state
on flash. We could do without that, given the new virtio-blk
support, but the code is already there, so reuse it and drop
all current virt64-specific board code.
As the barebox ELF image resulting from the build can no longer be
directly booted as before and only with -kernel, not -bios, rename
the Kconfig symbol, so existing users can notice this during build.

Add support for state and barebox environment by applying an overlay on
top of the qemu generated device tree. If qemu is used with a persistent
flash partition, this allows usage of environments and state across qemu
reboots.
Simple testing can be performed by starting with
qemu-system-arm -m 256M -M virt -kernel images/barebox-dt-2nd.img -nographic
Storing data, changing into the qemu console via Ctrl-A Ctrl-C, issuing
'system_reset' and Ctrl-A Ctrl-C to get back into the barebox console.

Necessary support to boot barebox on ARM qemu virt platforms.
No internal device tree, since it is passed by qemu. Therefore it
employs the generic 2nd stage image as the low level code and only adds
a virt specific board driver.

In preparation for the qemu virt image, move the KConfig options from
MACH_VEXPRESS to ARCH_VEXPRESS. Also remove the choice, since we allow
multiple boards to be selected with HAVE_PBL_MULTI_IMAGES.

This switches the VExpress support to use an internal DT, instead
of probing the peripherals from a board file. It also switches to
a multi-iamge build with both CA9 and CA15 variants of the VExpress
board being supported.

This allows to make more space available for the malloc area and
allows us to drop the special CA9 defconfig, which had a different
text base.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

detect the cpu model to dynamise the periphs mapping
currently only tested on qemu but should work on real hardware
Cortex-A9
if you use 1GiB of ram you can run the same barebox on Cortex-A15 or Cortex-A9
otherwise use vexpress_ca9_defconfig where the TEXT_BASE is at 0x63f00000
when we will add the relocation support this defconfig will be drop
