efi_driver: simplify error message

2019-02-13T08:40:05+00:00

Stating the function module is sufficient. We don't need file and line
number. Anyway the format code for the line number was incorrect (should
be %d).

blk: Call part_init() in the post_probe() method

2018-11-14T17:16:27+00:00

part_init() is currently called in every DM BLK driver, either
in its bind() or probe() method. However we can use the BLK
uclass driver's post_probe() method to do it automatically.

Update all DM BLK drivers to adopt this change.

efi_driver: blk: Switch to use platdata_auto_alloc_size for the driver data

2018-11-14T17:16:27+00:00

Currently the efi block driver uses priv_auto_alloc_size for the
driver data, however that's only available after the device probe
phase. In order to make it accessible in an earlier phase, switch
to use platdata_auto_alloc_size instead.

This patch is the prerequisite for the follow up patch of DM BLK
driver changes to work with EFI loader.

efi_driver: set DM_FLAG_NAME_ALLOCED flag

Set the DM_FLAG_NAME_ALLOCED flag to avoid a memory leak when the block
device is removed.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

efi_driver: return type of efi_driver_init()

2018-02-09T23:24:00+00:00

Change the return type of efi_driver_init() to efi_status_t.

efi_driver_init() calls efi_add_driver() which returns an efi_status_t
value. efi_driver_init() should not subject this value to a conversion to
int losing high bits on 64bit systems.

efi_driver: EFI block driver

2018-01-22T22:09:14+00:00

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices

For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol

The uclass provides the bind, start, and stop entry points for the driver
binding protocol.

In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.

The EFI block driver binds to controllers implementing the block io
protocol.

When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.

The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.

A usage example is as following:

U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.

Now the EFI block driver installs the partitions with the simple file
protocol.

iPXE uses the simple file protocol to load Grub or the Linux Kernel.
