The last block is of size media->block_size Signed-off-by: Jesper Schmitz Mouridsen Simplify expression. Apply same change to efi_disk_write_blocks(). Reviewed-by: Heinrich Schuchardt

efi_loader: install UEFI System Partition GUID

2021-02-04T19:09:02Z

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. Signed-off-by: Heinrich Schuchardt

efi_loader: correct block IO alignment check

2021-01-29T19:22:40Z

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. Fixes: f59f0825e8b9 ("efi_loader: parameter checks BLOCK_IO_PROTOCOL") Signed-off-by: Heinrich Schuchardt

efi_loader: correct EFI_BLOCK_IO_PROTOCOL.Media.LastBlock

2021-01-23T06:56:54Z

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 Reported-by: Alexander von Gluck IV Signed-off-by: Heinrich Schuchardt

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

2020-12-13T23:51:08Z

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. Signed-off-by: Simon Glass

efi_loader: link partition to block device

2020-12-10T08:15:33Z

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

2020-07-22T10:32:42Z

Use logging instead of printf() for messages occurring when scanning block devices during the initialization of the UEFI sub-system. Signed-off-by: Heinrich Schuchardt

efi_loader: check device path is not installed twice

2020-05-21T08:00:17Z

Prior to corrective patches for virtio and SATA devices the same device path was installed on two different handles. This is not allowable. With this patch we will throw an error if this condition occurs for block devices. Update a comment for the installation of the simple file system protocol.

part: Drop disk_partition_t typedef

2020-05-18T21:33:33Z

We should not be using typedefs and these make it harder to use forward declarations (to reduce header file inclusions). Drop the typedef. Signed-off-by: Simon Glass

efi_loader: disk: add efi_disk_is_system_part()

2020-05-04T10:26:11Z

This function will check if a given handle to device is an EFI system partition. It will be utilised in implementing capsule-on-disk feature. Signed-off-by: AKASHI Takahiro Add function description. Return bool. Reviewed-off-by: Heinrich Schuchardt
