What does Atlas need to do? If possible, I'd suggest having something like `void __weak mainboard_update_sot_table(void *sot_buf, size_t size) {}` (empty weak definition) and call it from `write_sot_table()`.

PS7, Line 575: 	size_t size = cbfs_load("fallback/sot", sot_buf, MAX_SOT_SIZE);
Is there a way to get the uncompressed size of a CBFS file at runtime? If so, it would be nice to use it to avoid allocating and then deallocating stuff in CBMEM, as well as to log a more detailed error when SOT size exceeds `MAX_SOT_SIZE` (and by how much).
