Hmm. Sure this caused by this patch series? For the PEI-less TDX
build this series moves the MTRR setup to a different place in SEC.
Once the DXE phase started the MTRR configuration should be identical
with and without this patch series, and the series also doesn't touch
any control register.
take care,
Gerd
