Upstream u-boot sunxi / allwinner support maintainer here. I would
love to
see BPI R1 defconfig + dts get submitted upstream officially, I will
happily merge them in u-boot and I'm sure the kernel devs will take the
dts too, assuming it passes review.
But it seems lots of people are working on the BPI R1, but no-one is
submitting patches upstream :|
Find my patches (dmesg fix and b53 switch driver) with latest release
Fedora kernel versions, please integrate it.
