I see this patch was sent a week ago. This is a standalone tool. There is no impact on normal build and boot. I am OK to add it for 201908 stable tag.

Thanks

Subject: [RFC] BZ 1837 Enable Windows Firmware Update Driver Tool in Edk2/BaseTools for 201908 stable tag

Hi All,

It is the request to Enable Windows Firmware Update Driver Tool in Edk2/BaseTools and catch the Q3 tag.
The new tool will leverage the edk2-pytool-library to generate the cat/inf file based on the cap file. The output driver package can be trigged in Windows OS to complete capsule update.
