The MM Core driver implements an entry point module which is architecture specific and runs prior to the generic core driver code. The former creates a Hob list that the latter consumes. This happens in the same phase. This patch implements a Hob library that can be used by the entry point module to produce a Hob list and by the core driver code to consume it.
