Please use upstream buildroot. Everything is in master for this board and
that v21 branch is dead now.

I used buildroot defconfigs sipeed_maix_bit_defconfig and
sipeed_maix_bit_sd_card_defconfig. Both had the same issue with SLUB: lots
of errors with the shell, including failures for the init shell commands.
And sometimes I end up with a prompt but no way to run any shell command
at all. I guess that depends on fragmentation of the memory after boot
completes.

Everything landed, plus some (some build fixes).

Palmer,

Please hold on before applying this patch. Discussion still going on about
SLUB.
