[PATCH 01/12] UefiPayloadPkg: Add HobLib for UniversalPayload


Zhiguang Liu
 

For payload entry, use PayloadEntryHobLib as HobLib and payload entry
should initialize hob base.
For DxeCore, use new added DxeHobLib as HobLib, and DxeCore will
initialize hob base.
For Dxe Driver, use new added DxeHobLib as HobLib, and use DxeHobListLib
to initialize hob base.

+ This library does not contain any functions or macros. It simply export=
s a global=0D

on Driver=0D
+ Execution Environment Core Interface Specification. The library constru=

to the start=0D
