Support dimm loop detection for the AMD platform
Description:
- Support detection of the DIMM loop pattern for the AMD platform
Design:
- The ipmi handler netfn=0x38,cmd=0x33 handles BIC incoming
postcode and call the detection function to check if this
is the DIMM loop pattern of AMD platform and store those
patterns in an in-memory space.
Reference from Meta_BIOS_Requirement_Spec_v0.80
For AMD platform, the POST code looping pattern format should be:
(each group has 4 bytes)
●Group #0: [DDEE0000]
●Group #1: [DDEE] + Total Error Count
●Group #2: [DDEE] + Number of Error DIMM
●Group #3: [DDEE] + Dimm location
●Group #4: [DDEE] + major code
●Group #5: [DDEE] + minor code
