dm: sandbox: Switch over to using the new host uclass

2022-11-07T23:24:30+00:00

Update the sandbox implementation to use UCLASS_HOST and adjust all
the pieces to continue to work:

- Update the 'host' command to use the new API
- Replace various uses of UCLASS_ROOT with UCLASS_HOST
- Disable test_eficonfig since it doesn't work (this should have a unit
  test to allow this to be debugged)
- Update the blk test to use the new API
- Drop the old header file

Unfortunately it does not seem to be possible to split this change up
further.

efi_loader: discover if no efi_system_partition is set

2022-11-06T09:50:04+00:00

Variable efi_system_partition holds the efi_system_partition. Currently it
is initialized as:

    {
      .uclass_id = 0 = UCLASS_ROOT,
      .denum = 0,
      .part = 0,
    }

This indicates that host 0:0 is the efi_system_partition and we see output
like:

    => bootefi hello
    ** Bad device specification host 0 **
    Couldn't find partition host 0:0

To identify that no EFI system partition has been set use UCLASS_INVALID.

disk: Rename block functions

Use the uclass type as the first part of the function name, to be
consistent with the methods in other block drivers.

Make it clearer why InstallMultipleProtocolInterfaces is invoked with two
NULLs:

* rename guid to esp_guid
* put protocol GUIDs and the related interfaces on same lines

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_driver: move event registration to driver

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

Move the registration of events for the addition and removal of block
devices to the block device driver. Here we can add a reference to the
EFI Driver Binding protocol as context.
