efi_driver: don't bind internal block devices

2022-09-09T14:07:54+00:00

UEFI block devices can either mirror U-Boot's internal devices or be
provided by an EFI application like iPXE.

When ConnectController() is invoked for the EFI_BLOCK_IO_PROTOCOL
interface for such an application provided device we create a virtual
U-Boot block device of type "efi_blk".

Currently we do not call ConnectController() when handles for U-Boot's
internal block devices are created. If an EFI application calls
ConnectController() for a handle relating to an internal block device,
we erroneously create an extra "efi_blk" block device.

E.g. the UEFI shell has a command 'connect -r' which calls
ConnectController() for all handles with device path protocol.

In the Supported() method of our EFI_DRIVER_BINDING_PROTOCOL return
EFI_UNSUPPORTED when dealing with an U-Boot internal device.

efi_loader: move udevice pointer into struct efi_object

2022-08-13T09:09:49+00:00

This is a preparation patch to provide the unified method
to access udevice pointer associated with the EFI handle
by adding udevice pointer into struct efi_object.
The patch also introduces a helper function efi_link_dev()
to link the udevice and EFI handle.

The EFI handles of both EFI block io driver implemented in
lib/efi_loader/efi_disk.c and EFI block io driver implemented
as EFI payload can access the udevice pointer in the struct efi_object.
We can use this udevice pointer to get the U-Boot friendly
block device name(e.g. mmc 0:1, nvme 0:1) through EFI handle.

efi_loader: disk: a helper function to create efi_disk objects from udevice

2022-04-23T20:05:41+00:00

Add efi_disk_probe() function.
This function creates an efi_disk object for a raw disk device (UCLASS_BLK)
and additional objects for related partitions (UCLASS_PARTITION).

So this function is expected to be called through driver model's "probe"
interface every time one raw disk device is detected and activated.
We assume that partition devices (UCLASS_PARTITION) have been created
when this function is invoked.

efi: Rename UCLASS_EFI and IF_TYPE_EFI

2021-12-09T19:43:25+00:00

These names are better used for access to devices provided by an EFI
layer. Use EFI_LOADER instead here, since these are only available in
U-Boot's EFI_LOADER layer.

efi_loader: Drop code that doesn't work with driver model

2021-10-21T01:46:03+00:00

This code should never have been added as it builds a new feature on top
of legacy code. This has already been improved with the dependency on BLK.

Add a dependency on DM_ETH also, to avoid needing to deal with this old
code.

Boards which want EFI_LOADER should migrate to driver model first.

dm: treewide: Rename ..._platdata variables to just ..._plat

Try to maintain some consistency between these variables by using _plat as

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

efi_loader: replace printf by log in efi_uclass.c

Use logging functions instead of printf() and debug().

Change logging messages for uclass creation and destruction to log_debug().
