Adapting memory addresses may not start from 0x0,
for example, the starting memory address starts
from 0x8000_0000.
I understand: LowestMemBase is the lowest DDR
address in the system.
UefiMemoryBase = LowestMemBase +
CodeSize(opensbi+UEFI);
LowestMemSize -= CodeSize(UefiMemoryBase -
LowestMemBase)
