[bug#39617] [PATCH 0/2] Add initial Pinebook Pro support

[Jan Nieuwenhuizen <janneke@gnu.org>]

Hello ARM Gurus!

These patches add initial Pinebook Pro support.  There are several rough edges,
your help would be much appreciated!

A vanilla kernel does not work yet; apparently development to upstream
pinebook-pro patches lives here:
https://gitlab.manjaro.org/tsys/linux-pinebook-pro

Similarly, Das U-Boot has a pinebook-pro development branch
https://git.eno.space/pbp-uboot.git

Because of "guix pull failing on aarch64"

    https://issues.guix.gnu.org/issue/39352

these patches must be applied on top of

    c7dd15596ffd09ab40629c89e7014e51a4d7e95e

(or use branch wip-pinebook-pro from https://gitlab.com/janneke/guix.git)

To install Guix System on the microSD in a Pinebook Pro, do something
like

--8<---------------cut here---------------start------------->8---
sudo mount /dev/mmcblk0p1 /mnt
sudo -E ./pre-inst-env guix system init gnu/system/examples/pinebook-pro.tmpl /mnt
sudo -E ./pre-inst-env guix system init arm-baar.scm /mnt
sudo sed 's,FDTDIR \([^ ]*\),FDT \1/rockchip/rk3399-pinebook-pro.dtb,' /boot/extlinux/extlinux.conf
--8<---------------cut here---------------end--------------->8---

Because of the aarch64 guix pull problem, the separate repositories for
kernel and u-boot, the weird MMC numbering changes /dev/mmcblk0 <->
/dev/mmcblk1 and this ugly extlinux.conf fixup I am not sure where to
share this code, maybe wip-pinebook-pro @ savannah.  WDYT?

For more details, see

I think it would be nice to have an updated this blog on guix.gnu.org when
these silly problems are resolved.

Greetings,
janneke
