to look at the new patch set (#2).
Change subject: src/cpu/amd/pi/00730F01: Add microcode update infrastructure for fam16h PI ......................................................................
src/cpu/amd/pi/00730F01: Add microcode update infrastructure for fam16h PI
Code is based on microcode update procedure from fam10-15h with necessary microcode blob structure updates for fam16h.
Currently updating microcode in romstage seem to be impossible. AGESA is overriding the microcode patch regardles of the current microcode revision patched on CPU. Use ramstage CPU init procedures to update microcode easily. Tested with microcode blob 07030106 released 2018-02-09 from platomav/CPUMicrocodes GitHub repository on apu2 platform.
TEST=boot Linux kernel 4.14.50 on PC Engines apu2 and run dmesg to see patch_level=0x07030106 on all cores
