This patch aims to improve the microcode in CBFS handling that was brought by the last patches from Stefan and the Chromium team. Choices in Kconfig - 1) Generate microcode from tree (default) - 2) Include external microcode file - 3) Do not put microcode in CBFS The idea is to give the user full control over including non-free blobs in the final ROM image. MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode is handled by a special class, cpu_microcode, as such: cpu_microcode-y += microcode_file.c MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is needed by intel microcode updating. Once all intel cpus are converted to cbfs updating, this variable can go away. These files are then compiled and assembled into a binary CBFS file. The advantage of doing it this way versus the current method is that 1) The rule is CPU-agnostic 2) Gives user more control over if and how to include microcode blobs 3) The rules for building the microcode binary are kept in src/cpu/Makefile.inc, and thus would not clobber the other makefiles, which are already overloaded and very difficult to navigate.
