2023-06-14mb/google/skyrim: Use CMOS bit to toggle ABL WA for Hynix DRAMMatt DeVillier
One specific Hynix LPDDR5x DRAM part requires an ABL workaround to eliminate DRAM-related failures during a FAFT test, but due to the use of generic/common SPDs, there is no way for the ABL to determine the DRAM part # itself. Consequently, we will have coreboot check the DRAM part #, and set/clear a CMOS bit as appropriate, which the ABL will check in order to apply (or not apply) the workaround. The ABL already uses byte 0xD of the extended CMOS ports 72/73 for memory context related toggles, so we will use a spare bit there. BUG=b:270499009, b:281614369, b:286338775 BRANCH=skyrim TEST=run FAFT bios tests on frostflow, markarth, and whiterun without any failures.
