efi_loader: Remove

2023-12-21T13:54:37+00:00

We largely do not need  in these files, so drop it. The only
exception here is that efi_freestanding.c needs  and had
been getting that via .

Correct SPL use of EFI_UNICODE_COLLATION_PROTOCOL2

2023-02-09T21:32:26+00:00

This converts 1 usage of this option to the non-SPL form, since there is
no SPL_EFI_UNICODE_COLLATION_PROTOCOL2 defined in Kconfig

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: remove EFI_UNICODE_COLLATION_PROTOCOL

2021-01-20T07:17:17+00:00

In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2
language codes existed. This protocol is not part of the UEFI specification
any longer. It was however required to run the UEFI Self Certification Test
(SCT) II, version 2.6, 2017. So we implemented it for the sole purpose of
running the SCT.

As the SCT does not need the protocol anymore it is time for removal.

efi_loader: EFI_DEVICE_PATH_UTILITIES_PROTOCOL configurable

2021-01-20T07:17:17+00:00

Allow the EFI_DEVICE_PATH_UTILITIES_PROTOCOL to be disabled via
configuration.

On systems that are very tight on U-Boot image size we may want to disable
the protocol. As it is required to run the UEFI Shell enable it by default.

A boot manager like GRUB can use the protocol to

* apply U-Boot's fix-ups to the a device-tree
* let U-Boot make memory reservations according to the device-tree
* install the device-tree as a configuration table

efi_loader: remove EFI_HII_CONFIG_ROUTING_PROTOCOL

2020-12-10T08:15:32+00:00

Our implementation of the EFI_HII_CONFIG_ROUTING_PROTOCOL is a mere stub,
where all services return an error code. The protocol is neither needed for
the EFI shell nor for the UEFI SCT. To reduce the code size remove it from
the U-Boot binary.
