The Intel Firmware Support Package (FSP) requires that microcode be provided very early before the device tree can be scanned. We already support adding a pointer to the microcode data in a place where early init code can access. However this just points into the device tree and can only point to a single lot of microcode. For boards which may have different CPU types we must support multiple microcodes and pass all of them to the FSP in one place. Enhance ifdtool to scan all the microcode, place it together in the ROM and update the microcode pointer to point there. This allows us to pass multiple microcode blocks to the FSP using its existing API. Enable the flag in the Makefile so that this feature is used by default for all boards.

# We are using a recursive build, so we need to do a little thinking

# to get the ordering right.
|
|
#
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
# their own directory. If in some directory we have a dependency on
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
# after that we are sure that everything which is in that other dir
|
|
# is now up to date.
|
|
#
|
|
# The only cases where we need to modify files which have global
|
|
# effects are thus separated out and done before the recursive
|
|
# descending is started. They are now explicitly listed as the
|
|
# prepare rule.
