Ard:
I just run BaseTools\Scripts\PatchCheck.py to check the latest patches. It
reports one issue in this patch. Could you fix it?
The commit message format passed all checks.
Code format is not valid:
* Line ending ('\n') is not CRLF
File: BaseTools/Scripts/GccBase.lds
Line: *(.hash .gnu.hash)
Thanks
Liming
