PS3: 
Like to share one observation before we enable this feature on ADL.

Currently we have fixed size cbmem console which is 8K in size and for sure not enough to hold the entire FSP-M debug log (after the CL gets landed). Typically, FSP-M debug log is very detailed and size is significantly high and I'm afraid we might not able to accommodate the same inside `cbmem -c`. I have verified that we are able to contain entire ramstage log inside `cbmem -c` with FSP debug enabled.

    default 0x2000
