FSP: Use BOOTLOADER_TOLUM and FSP_RESERVED_MEMORY HOBs
Adjust the memory map to allow CBMEM root to be placed at the top of low
usable memory. The memory map routines start by determining the base of
TSEG. The routines then need to skip over the chipset reserved memory
region. The CONFIG_CHIPSET_RESERVED_MEM_BYTES value was added to make
this easier and to reduce the number of register references. The base
of the chipset reserved memory area is also the top of the CBMEM root
area.
Remove the use of CONFIG_FSP_RESERVED_MEM_SIZE.
Always validate that the FSP binary properly implements Sections 7.2 and
7.4 of the FSP 1.1 specification.
