efi_loader: remove efi_delete_handle on loadfile2

2022-10-16T10:23:22+00:00

Loadfile2 code is installing two protocols on it's own handle
and uses efi_delete_handle() to clean it up on failure(s). However
commit 05c4c9e21ae6 ("efi_loader: define internal implementations of
install/uninstallmultiple") prepares the ground for us to clean up
efi_delete_handle() used in favor of Install/UninstallMultipleProtocol.

While at it clean up the non needed void casts to (void *) on the
protolcol installation.

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

efi_loader: function to unlink udevice and handle

2022-10-06T20:54:57+00:00

When deleting a device or a handle we must remove the link between the two
to avoid dangling references.

Provide function efi_unlink_dev() for this purpose.
