efi_loader: define internal implementations of install/uninstallmultiple

2022-10-06T20:54:58+00:00

A following patch is cleaning up the core EFI code trying to remove
sequences of efi_create_handle, efi_add_protocol.

Although this works fine there's a problem with the latter since it is
usually combined with efi_delete_handle() which blindly removes all
protocols on a handle and deletes the handle.  We should try to adhere to
the EFI spec which only deletes a handle if the last instance of a protocol
has been removed.  Another problem is that efi_delete_handle() never checks
for opened protocols,  but the EFI spec defines that the caller is
responsible for ensuring that there are no references to a protocol
interface that is going to be removed.

So let's fix this by replacing all callsites of
efi_create_handle(), efi_add_protocol() , efi_delete_handle() with
Install/UninstallMultipleProtocol.

In order to do that redefine functions that can be used by the U-Boot
proper internally and add '_ext' variants that will be used from the
EFI API

We cannot expect the buffers passed to the input protocols to be zero
filled. If only modifier keys are pressed, we have to return EFI_NOT_READY

efi_loader: initialize console size late

2022-06-19T13:53:09+00:00

If CONFIG_VIDEO_DM=n we query the display size from the serial console.
Especially when using a remote console the response can be so late that
it interferes with autoboot.

Only query the console size when running an EFI binary.

Add debug output showing the determined console size.
