For printing unsigned int %u has to be used. Signed-off-by: Heinrich Schuchardt

dfu: add 'SCRIPT' entity

2021-01-31T13:08:56Z

Define a new 'SCRIPT' type for DFU entities. The downloaded data are treated as simple u-boot's scripts and executed with run_command_list() function. Flashing the 'SCRIPT' entity might result in changing the 'dfu_alt_info' environment variable from the flashed script, so add a global variable for tracking the potential need to reinitialize the dfu_alt_info related structures.

dfu: add 'SKIP' entity

2021-01-31T13:08:56Z

Define a new 'SKIP' type for the DFU entities. The flashed data for that entity is simply ignored without returning any error values. This allows to have one flashing procedure and images for the different board types or variants, where each board uses only the images relevant to it and skips the rest. This is especially usefull for the THOR protocol, which usually transfers more than one file in a single session.

dfu: mmc: use the default MMC device if entity specifies it as -1

2021-01-31T13:08:56Z

Use the default MMC device set in the command line if entity specifies it as -1. This allows to use the same dfu_alt_info string for different MMC devices (like embedded eMMC and external SD card if data layout is the same on both devices). Signed-off-by: Marek Szyprowski

dfu: Fix handling of UBI partitions in MTD backend

2021-01-31T13:08:56Z

For UBI partitions ("partubi" in dfu_alt_info), dfu_fill_entity_mtd sets the mtd.ubi flag; however other functions incorrectly check for nand.ubi instead. Fix this by checking for the correct flag. Signed-off-by: Guillermo Rodriguez Cc: Lukasz Majewski Reviewed-by: Patrick Delaunay

dfu_mtd: Add provision to unlock mtd device

2020-12-31T13:41:31Z

Prior to writing to an mtd device, mtd_erase is called. This call fails in case the sector being erased is locked. Call mtd_unlock to unlock the region which is to be erased and later written to. Lock the region once the write to the region has completed. Signed-off-by: Sughosh Ganu

dfu: simplify the dependencies of DFU_TFTP

2020-11-21T06:26:16Z

Since CONFIG_UPDATE_COMMON always selects CONFIG_DFU_WRITE_ALT, we can drop the latter from dependencies of CONFIG_DFU_TFTP. Fixes: 3149e524fc1e ("common: update: add a generic interface for FIT image") Signed-off-by: AKASHI Takahiro Reviewed-by: Heinrich Schuchardt

dfu: add dfu_write_by_alt()

2020-10-30T13:20:27Z

This function is a variant of dfu_write_by_name() and takes a DFU alt setting number for dfu configuration. It will be utilised to implement UEFI capsule management protocol for raw image in a later commit. Signed-off-by: AKASHI Takahiro Reviewed-by: Tom Rini

dfu: export dfu_list

2020-10-30T13:20:27Z

This variable will be utilized to enumerate all dfu entities for UEFI capsule firmware update in a later commit. Signed-off-by: AKASHI Takahiro Reviewed-by: Tom Rini

common: update: add a generic interface for FIT image

2020-10-30T13:20:27Z

The main purpose of this patch is to separate a generic interface for updating firmware using DFU drivers from "auto-update" via tftp. This function will also be used in implementing UEFI capsule update in a later commit. Signed-off-by: AKASHI Takahiro Reviewed-by: Tom Rini
