PatchPcdValue.exe or PatchPcdValue.py - Patch the specific value into the binary image.
PatchPcdValue.exe -f Offset -u Value -t Type [-s MaxSize] <input_file>
PatchPcdValue tool sets the specific value into the binary image according to the input PCD offset and type. When PCD type is VOID*, MaxSize must be specified to say how much value need to be updated. This tool checks whether the input PCD information is valid for the input binary image, but doesn't check the format of the binary image.
PatchPcdValue tool usually works together with GenPatchPcdTable tool to set the specific value of a patchable PCD into the binary EFI image.

Patch 0x80000000 to the patchable PcdDebugPrintErrorLevel in the binary
PeiCore image. This PCD type is UINT32. Its offset in PeiCore image is 0x6F80
got by GenPatchPcdTable tool.
PatchPcdValue.exe -f 0x6F80 -u 0x80000000 -t UINT32 PeiCore.efi
Patch the unicode string "Test" to the patchable PcdHelloWorldPrintString
in the binary HelloWorld image. This PCD type is VOID*. Its max byte array
size is 0x40, and its offset in HelloWorld image is 0x3050.
PatchPcdValue.exe -f 0x3050 -t VOID* -s 0x40 -u "L Test" HelloWorld.efi
