* bbu: Emit a message about what happens also when -y is givenUwe Kleine-König2024-02-231-6/+12
| | | | | | | | | | | | To inform the user which device is updated using which handler, also emit a message with -y. Also update the wording to make the output more similar between the different cases.

* bbu: create a standard bbu handler for eMMC bootSascha Hauer2024-02-131-5/+33
| | | | | | | | | | | This adds a standard bbu handler to be used when an update is just a matter of writing an image to the eMMC boot partitions. As these may also want to set the BBU_FLAG_MMC_BOOT_ACK flag, it is moved up one level to struct bbu_handler::flags to make it configurable when struct bbu_data is not yet instantiated.

* bbu: make it possible to check multiple of-compatiblesMarco Felsch2023-04-041-13/+28
| | | | | | | | | | | | | It is possible that one barebox can rule multiple platforms e.g. multiple platform revision each has a dedicated device tree and of compatible. While it is possible to add multiple of-compatibles via IMD_USED_OF() (see: zii-imx8mq-dev) we didn't allowed it to flash it without 'force'. Fix this by check all possible IMD_TYPE_OF_COMPATIBLE image metadata types.

* bbu: fix exporting i.MX NAND bbu handler over fastbootAhmad Fatoum2022-09-301-19/+18
| | | | | | | | | | | | | | | | | handler->devicefile for i.MX NAND is nand0.barebox, which lacks a /dev/ prefix. This is ok for detection, as device_detect_by_name expects the cdev name and devpath_to_name() will strip a /dev/ if available. For stat() however, we need to add back /dev/, otherwise the file can't be found. Rework the code to do that. This fixes an issue where usbgadget -A '' -b would not export a i.MX NAND barebox update handler.

* bbu: export bbu_std_file_handler for use in custom handlersAhmad Fatoum2022-06-031-13/+20
| | | | | | | | | | | bbu_register_std_file_update() registers an update handler that updates a single file, usually a partition. Depending on SoC, we may want to compute the file path at install time. To save custom bbu code the hassle of reimplementing bbu_std_file_handler(), export it.

* bbu: add flag for enabling eMMC boot ackAhmad Fatoum2022-06-031-1/+16
| | | | | | | | | | | | | | bbu_mmcboot_handler() already takes care to switch $mmc.boot to the freshly read inactive partition. On some SoCs like the STM32MP1, this is not enough, but the boot ack bit must be set as well, so the BootROM can communicate with the eMMC. Have this happen as part of the eMMC boot switch after a successful update if bbu_data::flags has BBU_FLAG_MMC_BOOT_ACK set.

* bbu: move barebox_update eMMC boot handling into common codeAhmad Fatoum2022-06-031-0/+55
| | | | | | | | | | | | | Like with the i.MX, the STM32MP1 BootROM also consults the EXT_CSD_PARTITION_CONFIG register to find out what to boot. The barebox_update code used for atomic update on i.MX is thus useful to the STM32MP as well, so move the boot switching part to a generic location.

* Add in-system barebox update infrastructureSascha Hauer2012-10-171-0/+150
Currently in-system update means to write an arbitrary file to an arbitrary device. There is no sanity check if the flashed image is of the right type or will fit onto the device. Furthermore some SoCs need a special preparation step for their images before flashing them. This adds a barebox in-system update infrastructure. Boards can register update handlers which know how to make the board bootable. The available handlers can be listed to be able to select one, different force levels give the user the chance to know it better. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
