## Maximum address that the DXE Core will allocate the EFI_SYSTEM_TABLE_POINTER
# structure. The default value for this PCD is 0, which means that the DXE Core
# will allocate the buffer from the EFI_SYSTEM_TABLE_POINTER structure on a 4MB
# boundary as close to the top of memory as feasible. If this PCD is set to a
# value other than 0, then the DXE Core will first attempt to allocate the
# EFI_SYSTEM_TABLE_POINTER structure on a 4MB boundary below the address specified
# by this PCD, and if that allocation fails, retry the allocation on a 4MB
# boundary as close to the top of memory as feasible.
