[PATCH v1 0/2] EDK2 Code First: PI Specification: Update EFI_MM_COMMUNICATE_HEADER

Kun Qin

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3794

In current Status Codes definitions of PI spec v1.7 errata, there are a
few critical instances where the software could trigger system reboots
while the corresponding case were not covered by the already defined
status codes.

Two scenarios that OEMs could be interested are memory type information
change triggered system reboot and assert triggered reboot on systems
that did not enable system halts.

The unexpected system reboots above could indicate decay of system health
and reporting of such generic events would provide helpful information to
OEMs to investigate/prevent system failures in general.

The change intends to expand definitions of `EFI_SW_EC_**` under Status
Codes to cover more unexpected system reboot events, which could improve
Status Code futility and readability.
