338: Can you change to mUefiShellFileGuid and initialize it to zero? It
seems misleading to me to have the default value here when it is not used. I
think we should also move the declarations to the beginning of the file.
I am curious why this kind of global variable doesn't trigger PF and PCD does.
If you know off the top of your head. You do not need to research if the code
is functional with GCC. Also, please add me to CC list so I don't filter the
emails.
Thanks,
Isaac

Subject: [edk2-devel] [PATCH 2/2] BoardModulePkg: Adds PCD to load UEFI Shell
image
defines two PCDs, PcdShellFile and PcdShellFileDesc, which holds the GUID and
description of the UEFI shell file to be loaded.
A PCDs based solution gives flexibility to the user to load different images,
by just overriding the DSC file.
The user can load a diagnostic image or test image during PCDBootToShellOnly or
later stages.
