## The PCD is used to specify memory base address for OPROM to find free memory.
# Some OPROMs do not use EBDA or PMM to allocate memory for its usage,
# instead they find the memory filled with zero from 0x20000.
# The range should be below the EBDA reserved range from
# (CONVENTIONAL_MEMORY_TOP - PcdEbdaReservedMemorySize) to CONVENTIONAL_MEMORY_TOP.

## The PCD is used to specify memory size with bytes for OPROM to find free memory.
## The value should be a multiple of 4KB. And the range should be below the EBDA reserved range from
# (CONVENTIONAL_MEMORY_TOP - PcdEbdaReservedMemorySize) to CONVENTIONAL_MEMORY_TOP.

## The PCD is used to specify memory size with page number for a pre-allocated reserved memory to be used
# by PEI in S3 phase. The default size 32K. When changing the value of this PCD, the platform
# developer should make sure the memory size is large enough to meet PEI requiremnt in S3 phase.
