efi_loader: find distro device-path for media devices

2024-07-19T11:43:50+00:00

The auto-generated load options for media device do not contain a partition
node. We cannot expect the simple file protocol here.

Get the partition device-path via the loaded image protocol.

cmd: eficonfig: add support for setting fdt

2024-06-10T09:43:36+00:00

We already support creating a load option where the device-path
field contains the concatenation of the binary device-path and
optionally the device path of the initrd which we expose via the
EFI_LOAD_FILE2_PROTOCOL.

Allow to append another device-path pointing to the device-tree
identified by the device-tree GUID.

2024-06-10T09:43:36+00:00

Allow appending a device-path to a device-path that contains an end node
as separator. We need this feature for creating boot options specifying
kernel, initrd, and dtb.

efi_loader: pass GUID by address to efi_dp_from_lo

We should not pass GUIDs by value as this requires copying.

efi_loader: Add OS notifications for SetVariable at runtime

2024-04-20T06:22:24+00:00

Previous patches enable SetVariable at runtime using a volatile storage
backend using EFI_RUNTIME_SERVICES_DATA allocared memory. Since there's
no recommendation from the spec on how to notify the OS, add a volatile
EFI variable that contains the filename relative to the ESP. OS'es
can use that file and update it at runtime

$~ efivar -p -n b2ac5fc9-92b7-4acd-aeac-11e818c3130c-RTStorageVolatile
GUID: b2ac5fc9-92b7-4acd-aeac-11e818c3130c
