When building some xtensa config, I hit the following warning:
drivers/staging/mt7621-dts/Kconfig:4:warning: 'BUILTIN_DTB' has wrong type.
'select' only accept arguments of bool and tristate type
It is due to some arch use BUILTIN_DTB as a flag for the need to builtin
dtb but xtensa use it as a string for which dtb to bulltin.
But for this (which dtb to build), it is better to use
BUILTIN_DTB_SOURCE like other arch do.
