Zhiguang:
This is the common platform usage. I suggest to apply the same solution. My
solution is to define this PCD PcdBootState in MdeModulePkg.dec, and add
MdeModule.dsc.inc file that defines this PCD as DynamicHii PCD, platform DSC
includes MdeModule.dsc.inc file, platform modules consume this PCD (set/get).
Thanks
Liming
