efi_loader: check device path is not installed twice

2020-05-21T08:00:17+00:00

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

2020-05-18T21:33:33+00:00

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.

efi_loader: disk: add efi_disk_is_system_part()

2020-05-04T10:26:11+00:00

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.

Add function description. Return bool.

efi_loader: identify EFI system partition

2020-04-30T08:25:07+00:00

In subsequent patches UEFI variables shalled be stored on the EFI system
partition. Hence we need to identify the EFI system partition.

efi_loader: disk: install file system protocol to a whole disk

2019-11-12T22:13:54+00:00

Currently, a whole disk without any partitions is not associated
with EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. So even if it houses some
file system, there is a chance that we may not be able to access
it, particularly, when accesses are to be attempted after searching
that protocol against a device handle.

With this patch, EFI_SIMPLE_FILE_SYSTEM_PROTOCOL is installed
to such a disk if part_get_info() shows there is no partition
table installed on it.

Signed-off-by: AKASHI Takahiro 

Only if no partition table exists, check for a file system on disk level.

efi_loader: disk: install FILE_SYSTEM_PROTOCOL only if available

2019-10-17T17:19:56+00:00

In the current implementation, EFI_SIMPLEFILE_SYSTEM_PROTOCOL is always
installed to all the partitions even if some of them may house no file
system.

With this patch, that protocol will be installed only if any file system
exists.

efi_loader: EFI_BLOCK_IO_PROTOCOL.Reset()

2019-09-05T21:18:51+00:00

We cannot do anything in EFI_BLOCK_IO_PROTOCOL.Reset() but this does not
justify to return an error.

Let EFI_BLOCK_IO_PROTOCOL.Reset() return EFI_SUCCESS.
