Subject: efi_loader: move EFI_LOAD_FILE2_PROTOCOL_GUID
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-favicon.png?a=commitdiff_plain;h=b6f11098c9a619f480582b26edd26c5b195c69f4;p=u-boot.git

efi_loader: move EFI_LOAD_FILE2_PROTOCOL_GUID

The EFI_LOAD_FILE_PROTOCOL_GUID and EFI_LOAD_FILE2_PROTOCOL_GUID are needed
to complement the implementation of the LoadFile() boot service.

Remove a duplicate declaration of a variable for the
EFI_LOAD_FILE2_PROTOCOL_GUID.
Move the remaining declaration to efi_boottime.c.
Add a variable for the EFI_LOAD_FILE_PROTOCOL_GUID.
