I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/76076?usp=email
to look at the new patch set (#3).
Change subject: mb/google/rex: Avoid LPDDR5/x hang ......................................................................
mb/google/rex: Avoid LPDDR5/x hang
This patch avoids random hang issue observed after booted to OS on LPDD5/x platforms due to CLK not tuned properly in SAGV point 0, 2133MT/s.
As per Intel doc 769410 the expected work around is to change SAGV point 0 from 2133 G4 to 3200 G4.
BUG=b:287170545 TEST=Able to perform 500 power cycles on google/rex without any hang.
