MIPS: generic: Allow filtering enabled boards by requirements
Up until now when configuring a generic kernel all board config
fragments have been merged by default unless boards are explicitly
selected by the user specifying BOARDS=.
In many cases this is sub-optimal, since some boards don't make sense to
include in some kernels. For example the MIPS SEAD-3 development board
has only ever been used with 32 bit CPUs, so including support for the
SEAD-3 in a 64 bit kernel is wasteful.
This patch introduces support for specifying requirements in board
config fragments, using comments formatted like so:
# require CONFIG_BLA=y
For example the SEAD-3 board could specify that it should only be merged
for 32 bit kernels using a requirement line like the following:
# require CONFIG_32BIT=y
A new generic-board-config.sh script is introduced to handle selecting
the board config fragments to merge & calling merge_config.sh to merge
them. In order to allow requirements to check Kconfig symbols that are
implicitly selected, rather than explicitly specified by
generic_defconfig or one of the ISA config fragments, an intermediate
.config file is saved & used as a reference when checking requirements.
