+### CBMEM init hooks changed
+
+Instead of having per stage x_CBMEM_INIT_HOOK, we now have only 2 hooks:
+* CBMEM_CREATION_HOOK: Used only in the first stage that creates cbmem,
+ typically romstage. For instance code that migrates data from cache
+ as ram to dram would use this hook.
+* CBMEM_READY_HOOK: Used in every stage that has cbmeme. An example would
+ initializing the cbmem console by appending to what previous stages
+ logged.
+This reason for this change is improved flexibility with regards to which
+stage initializes cbmem.
