Subject: [PATCH 0/3] New SMCA Syndrome registers and FRU Text feature

Hello,

This patchset adds support for two new "syndrome" registers used in
future AMD Scalable MCA (SMCA) systems and also a new "FRU Text in MCA"
feature that uses these new registers.

Patch 1 adds support for the new registers. They are read/printed
wherever the existing MCA_SYND register is used.

Patch 2 updates the function that pulls MCA information from UEFI x86
Common Platform Error Records (CPERs) to handle systems that support the
new registers.

Patch 3 adds support to the AMD MCE decoder module to detect and use the
"FRU Text in MCA" feature which leverages the new registers.

Thanks,
Yazen
