Subject: efi_loader: expose protocols via GUID
X-Git-Tag: v2017.09-rc1~13^2~10
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a17e62cc533b8eb59616fc21001be90685770a06;p=u-boot

efi_loader: expose protocols via GUID

shim.efi (or rather gnu-efi's LibLocateProtocol() which shim.efi uses)
resolves protocols via efi_locate_handle() so the console protocols
need to be added to the efi object list.
