[coreboot] Bring up Intel Camelback Mountain Board with coreboot+FSP failed

[Zoran Stojsavljevic]

Hello Werner,

Could be that you are correct. I know that INTEL PED team themselves
up-streamed the whole BDW-DE Coreboot code into Coreboot. Here is the
pointer proving that:
https://www.coreboot.org/pipermail/coreboot-gerrit/2016-April/042490.html

+config CPU_MICROCODE_HEADER_FILES
+	string
+	default "../intel/cpu/broadwell_de/microcode/M1050663_07000001.h
../intel/cpu/broadwell_de/microcode/M1050662_0000000A.h
../intel/cpu/broadwell_de/microcode/MFF50661_F1000008.h"

The same I found in Jim's Coreboot config files:

# CONFIG_BUILD_WITH_FAKE_IFD is not set
CONFIG_TTYS0_BASE=0x3f8
CONFIG_CPU_MICROCODE_HEADER_FILES="../intel/cpu/broadwell_de/microcode/M1050663_07000001.h

../intel/cpu/broadwell_de/microcode/M1050662_0000000A.h

../intel/cpu/broadwell_de/microcode/MFF50661_F1000008.h"
CONFIG_FSP_LOC=0xffeb0000
CONFIG_SOC_INTEL_FSP_BROADWELL_DE=y

York (Yang) is the one who can precisely answer on these questions.
and maybe provide the latest MCUs, or at least these could be used for
googlthe more recent BDX-DE MCUs.

Also, BDX-DE CPUID is important (I think for CPUIDs 0x50661, 0x50662,
0x50663 and assuming also 0x50664), so for different CPUIDs different
MCU updates should be used (not 100% sure, thought).

Best Regards,

Zoran
