efi_loader: implement deprecated Unicode collation protocol

2019-05-19T06:10:10+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. Unfortunately it is required to run the UEFI Self Certification
Test (SCT) II, version 2.6, 2017. So we implement it here for the sole
purpose of running the SCT. It can be removed once a compliant SCT is
available.

The configuration option defaults to no.

Signed-off-by: Rob Clark 

Most of Rob's original patch is already merged. Only the deprecated
protocol is missing. Rebase it and make it configurable.

Rename variables to make it clear they refer to the Unicode collation
protocol identified by the EFI_UNICODE_PROTOCOL2_GUID.

efi_loader: make device path to text protocol customizable

2019-05-12T18:54:22+00:00

The device path to text protocol is not needed for EBBR compliance. So
let's make it a customizable option.

efi_loader: make Unicode collation protocol customizable

2019-05-12T18:54:22+00:00

The Unicode collation protocol is not needed for EBBR compliance. So let's
make it a customizable option.

The Unicode capitalization table is only needed by this protocol. So let it
depend on the Unicode collation protocol.

efi_loader: LoadImage() check parent image

2019-05-07T19:10:04+00:00

If the parent image handle does not refer to a loaded image return
EFI_INVALID_PARAMETER.
(UEFI SCT II 2017: 3.4.1 LoadImage() - 5.1.4.1.1)

Mark our root node as a loaded image to avoid an error when using it as
parent image.

efi_loader: export root node handle

2019-04-22T22:37:27+00:00

This is a preparatory patch.
The root node handle will be used as a dummy parent handle when invoking
an EFI image from bootefi/bootmgr command.

efi_loader: assign HII protocols to root node

2019-04-12T20:00:41+00:00

We should not install the HII protocols on every loaded image. It is
sufficient to install them once on the root node.

efi_loader: create root node

2018-09-23T19:55:31+00:00

Currently we assign a lot of protocols to loaded images though
these protocols are not related to them. Instead they should be
installed on a separate handle. Via the device path it is the
parent to the devices like the network adapter.
