Patch Set #4, Line 15: chausie
I'm sure you could easily get one ;) […]
The ABL will tell us exactly how big the APOB is in the header field. We reserve at least that much, probably rounded to the next biggest erasable block size (4k usually). It's likely there is space at the end for this, but until I can test on actual hardware it's only a guess.
File src/soc/amd/common/block/apob/apob_cache.c:
Patch Set #4, Line 57: apob_header_ptr->size + MRC_HASH_SIZE
We know this via `CONFIG_PSP_APOB_DRAM_SIZE` don't we?
The actual size for Mendocino looks to be 0x1db18 which is why we reserved 0x1e000 (120k). This leaves 1256 bytes free, of which the hash will use 8.
