efi_loader: efi_disk_register() should not fail

2021-11-26T20:30:59+00:00

Our algorithm for creating USB device paths may lead to duplicate device
paths which result in efi_disk_register() failing. Instead we should just
skip devices that cannot be registered as EFI block devices.

Fix a memory leak in efi_disk_add_dev() caused by the duplicate device
path.

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.

efi_loader: partition numbers are hexadecimal

2021-06-08T22:16:39+00:00

If we want to address partition 15 of virtio block device 11, we have to
write:

	virtio b:f

When calling sprintf() we must use %x for the device and partition numbers.

Allow last block to be read

2021-02-21T08:21:35+00:00

The last block is of size media->block_size

Simplify expression.
Apply same change to efi_disk_write_blocks().

efi_loader: install UEFI System Partition GUID

2021-02-04T19:09:02+00:00

On the handle for the UEFI System Partition we must install the System
Partition GUID (with a NULL interface).

Let the efidebug command display the GUID.

efi_loader: correct block IO alignment check

2021-01-29T19:22:40+00:00

If the field Media->IoAlign of the EFI block IO protocol is zero, no
alignment is required. Our code required 4 GiB alignment in this case.

Don't check buffer alignment if Media->IoAlign == 0.

efi_loader: correct EFI_BLOCK_IO_PROTOCOL.Media.LastBlock

2021-01-23T06:56:54+00:00

The field Media.LastBlock of the EFI_BLOCK_IO_PROTOCOL.Media was filled
incorrectly both for block devices as well as for partitions.

The field must be filled with the index of the last logical block (LBA):

* block devices: device size minus 1
* partitions: partition size minus 1

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.

efi_loader: link partition to block device

2020-12-10T08:15:33+00:00

We provide a UEFI driver for block devices. When ConnectController() is
called for a handle with the EFI_BLOCK_IO_PROTOCOL this driver creates the
partitions. When DisconnectController() is called the handles for the
partitions have to be deleted. This requires that the child controllers
(partitions) open the EFI_BLOCK_IO_PROTOCOL of the controller (block IO
device) with attribute EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.

efi_loader: use logging for block device messages

2020-07-22T10:32:42+00:00

Use logging instead of printf() for messages occurring when scanning block
devices during the initialization of the UEFI sub-system.
