[edk2-devel] [PATCH] SG2042Pkg/Sec:Modify Calculation LowestMemSize

["WangYang" <wangyang@bosc.ac.cn>]

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)
