Subject: [edk2-devel] [PATCH V2 01/10] EmbeddedPkg: Fix a build error in
FwVol.c in X64 arch

RFC:
INVALID URI REMOVED
d=3429__;!!NpxR!xMRxJim2LXdgV0CClUrT7jWBUouLzrVwMc5fB_wt1PT17W
WWyZKgREYswYM1Tz0$

CompressedDataLength is declared as UINTN which is UINT64 in X64 arch.
But the second parameter of UefiDecompressGetInfo() is declared as
UINT32. So a build error is triggered. To declare CompressedDataLength
as UINT32 to fix the build error.
