I just grep-ed in the source for CONFIG_CMD_UBI and CONFIG_MTD_UBI, and
it seems that all boards have been converted to select the Kconfig
option instead of having it defined in their <board>.h config header.

This means you could to drop the 'if ARCH_SUNXI' and add the changes
you get after executing the following command to this commit:

# git grep -l "#define CONFIG_RBTREE" | \
  xargs sed -i "/#define CONFIG_RBTREE/d"

Of course, i's just a suggestion, ans we can do that after this series
has been merged.
