2023-09-19FWU: Avoid showing an unselectable menu optionSimon Glass

2023-08-31event: Convert existing spy records to simpleSimon Glass
Very few of the existing event-spy records use the arguments they are passed. Update them to use a simple spy instead, to simplify the code. Where an adaptor function is currently used, remove it where possible. Signed-off-by: Simon Glass <sjg@chromium.org>
2023-08-30fwu: Initialize global fwu library state during CI testMarek Vasut
The current CI test worked by sheer luck, the g_dev global pointer in the fwu library was never initialized and the test equally well failed on sandbox64. Trigger the main loop in sandbox tests too to initialize that global state, and move the sandbox specific exit from fwu_boottime_checks after g_dev is initialized.

Code rewrites the last char of size with adding &. It is visible from dfu_alt_info print before this patch: Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000 8000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000' And after it: Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000 80000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000' Size for bank0 and bank1 must be the same because it is the same image.

2023-07-25fwu: Allow code to properly decode trial stateMichal Simek
Current code after capsule update (mtd write) is not changing active_index in mdata to previous_active_index. On the reboot this is shown but showing message "Boot idx 1 is not matching active idx 0, changing active_idx" which is changing active_idx and writing mdata to flash. But when this message is visible it is not checking which state that images are. If they have acceptance bit setup to yes everything is fine and valid images are booted (doesn't mean the latest one). But if acceptance bit is no and images are in trial state in_trial variable is never setup. Which means that from new flashed image stable image can be rewritten because in_trial is not setup properly.

2023-06-09FWU: Add FWU metadata access driver for MTD storage regionsMasami Hiramatsu
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 <masami.hiramatsu@linaro.org> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>

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.

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.

2022-10-31test: dm: Add test cases for FWU Metadata uclassSughosh Ganu
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.

2022-10-31FWU: Add support for the FWU Multi Bank Update featureSughosh Ganu
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.

2022-10-31FWU: Add boot time checks as highlighted by the FWU specificationSughosh Ganu
The FWU Multi Bank Update specification requires the Update Agent to carry out certain checks at the time of platform boot. The Update Agent is the component which is responsible for updating the firmware components and maintaining and keeping the metadata in sync. The spec requires that the Update Agent perform the following checks at the time of boot * Sanity check of both the metadata copies maintained by the platform. * Get the boot index passed to U-Boot by the prior stage bootloader and use this value for metadata bookkeeping. * Check if the system is booting in Trial State. If the system boots in the Trial State for more than a specified number of boot counts, change the Active Bank to be booting the platform from. Call these checks through the main loop event at the time of platform boot.

2022-10-31FWU: Add helper functions for accessing FWU metadataSughosh Ganu
Add weak functions for getting the update index value and dfu alternate number needed for FWU Multi Bank update functionality. The current implementation for getting the update index value is for platforms with 2 banks. If a platform supports more than 2 banks, it can implement it's own function. The function to get the dfu alternate number has been added for platforms with GPT partitioned storage devices. Platforms with other storage partition scheme need to implement their own function.

2022-10-31FWU: Add FWU metadata structure and driver for accessing metadataSughosh Ganu
In the FWU Multi Bank Update feature, the information about the updatable images is stored as part of the metadata, which is stored on a dedicated partition. Add the metadata structure, and a driver model uclass which provides functions to access the metadata. These are generic API's, and implementations can be added based on parameters like how the metadata partition is accessed and what type of storage device houses the metadata.
