Patch Set 2: Code-Review-1

This patch leads to a non booting board.
It hangs somewhere in imd_create_empty() which is called form romstage_main_continue() by the line

cbmem_was_initted = !cbmem_recovery(0);

in romstage.c (last postcode is 0x4d).
I haven't dug that deep due to time constraints but it looks like the cache-as-ram memory space is not available anymore (which is the case for broadwell-de in romstage_main_continue) while it is still used by the cbmem-code. Let me know if you need further tests.
