acpica-tools/0026-Support-NFIT-in-a-big-endian-world.patch
Al Stone fc3eef63e8 Update to 20220331 upstream sources 
This includes new source tarballs, updated patches, and updated
expected results for test cases.  In addition, three new tables
(PRMT, RGRT and SVKL) now have big-endian support.

Subject: [PATCH 26/45] Support NFIT in a big-endian world
NB: this required correcting the starting pointer for the NFIT
SMBIOS subtable; otherwise, disassembly did not work properly.
