Hi!

I did a rebase onto commit 2e8b4f9bfa00489fd3acff305837a79af236e183.

Vagrant, there was a comment left about removing "CONFIG_BOOTDELAY=1" for the u-boot, this is now done. I think all review comments have been applied.

There is a new u-boot-rockpro64-rk3399 which I adapted as well to use the #:configs keyword argument.

The function modify-defconfig in guix/build/kconfig.scm no longer interprets "CONFIG_XY=" like "# CONFIG_XY is not set".


Bye

Stefan
