fwu: provide default fwu_plat_get_bootidx

2023-06-09T17:52:40Z

Just like fwu_plat_get_update_index, provide a default/weak implementation of fwu_plat_get_bootidx. So that most platforms wouldn't have to re-implement the likely case. Signed-off-by: Jassi Brar

FWU: Add FWU metadata access driver for MTD storage regions

2023-06-09T17:52:40Z

In the FWU Multi Bank Update feature, the information about the updatable images is stored as part of the metadata, on a separate region. Add a driver for reading from and writing to the metadata when the updatable images and the metadata are stored on a raw MTD region. The code is divided into core under drivers/fwu-mdata/ and some helper functions clubbed together under lib/fwu_updates/ Signed-off-by: Masami Hiramatsu Signed-off-by: Jassi Brar

fwu: rename fwu_get_verified_mdata to fwu_get_mdata

fwu_get_mdata() sounds more appropriate than fwu_get_verified_mdata() Signed-off-by: Jassi Brar Reviewed-by: Etienne Carriere Reviewed-by: Ilias Apalodimas Tested-by: Sughosh Ganu

fwu: meta-data: switch to management by common code

2023-06-09T17:52:40Z

The common code can now read, verify and fix meta-data copies while exposing one consistent structure to users. Only the .read_mdata() and .write_mdata() callbacks of fwu_mdata_ops are needed. Get rid of .get_mdata() .update_mdata() .get_mdata_part_num() .read_mdata_partition() and .write_mdata_partition() and also the corresponding wrapper functions.

fwu: move meta-data management in core

2023-06-09T17:49:55Z

Instead of each i/f having to implement their own meta-data verification and storage, move the logic in common code. This simplifies the i/f code much simpler and compact. Signed-off-by: Jassi Brar Reviewed-by: Ilias Apalodimas Tested-by: Sughosh Ganu

efi_loader: add the number of image entries in efi_capsule_update_info

2023-06-08T07:20:36Z

The number of image array entries global variable is required to support EFI capsule update. This information is exposed as a num_image_type_guids variable, but this information should be included in the efi_capsule_update_info structure. This commit adds the num_images member in the efi_capsule_update_info structure. All board files supporting EFI capsule update are updated.

test: dm: Add test cases for FWU Metadata uclass

2022-10-31T18:47:33Z

Add test cases for accessing the FWU Metadata on the sandbox platform. The sandbox platform also uses the metadata access driver for GPT partitioned block devices. The FWU feature will be tested on the sandbox64 variant with a raw capsule. Remove the FIT capsule testing from sandbox64 defconfig -- the FIT capsule test will be run on the sandbox_flattree variant.

FWU: Add support for the FWU Multi Bank Update feature

2022-10-31T18:47:32Z

The FWU Multi Bank Update feature supports updating firmware images to one of multiple sets(also called banks) of images. The firmware images are clubbed together in banks, with the system booting images from the active bank. Information on the images such as which bank they belong to is stored as part of the metadata structure, which is stored on the same storage media as the firmware images on a dedicated partition. At the time of update, the metadata is read to identify the bank to which the images need to be flashed(update bank). On a successful update, the metadata is modified to set the updated bank as active bank to subsequently boot from. Signed-off-by: Sughosh Ganu Acked-by: Ilias Apalodimas
