Fri Jul 30 10:22:29 UTC 2021
Bugzilla: 3516 (https://bugzilla.tianocore.org/show_bug.cgi?id=3516)
This patch introduces a header file for the ACPI specification version
6.4. Currently it is based on the Acpi63.h header file however makes
six changes:
1. Replace all occurences of "6_3"/"6.3" with "6_4/6.4".
2. Remove the trailing underscore from the header guard in accordance
with the EDK2 coding standards, section 5.3.5.
3. Make Acpi64.h the latest ACPI definition included by Acpi.h.
4. Fix the BGRT Status field comment to match the ACPI 6.3A spec.
5. Fix several typos where definitions were named "PMMT" when it should
be "PMTT".
6. Fix a typo: "PPTT Platform Communication Channel" should be "PDTT
Platform Communication Channel".
