AFAIK footbridge_defconfig is for the "Compaq Personal Server", which
is different than NetWinder. They could probably be reconciled by
using devicetree and converting any platform devices. However testing
could be a challenge, not sure who has working hardware anymore.

Interesting. I successfully used netwinder_defconfig a few years ago.

I have several times thought about updating the netwinder, starting
with a more modern bootloader (I got u-boot working at one point), so
we no longer need ATAGS. However toolchain support is problematic
("bx" hack anyone?) and there are so many cheaper faster boards (RPi
for example) which require much less effort.
