fastboot: reinit partition after storing GPT or MBR

2021-02-07T18:22:55Z

In case MMC has MBR system and fastboot writes GPT, MMC is still recognized as MBR. Invoke part_init() to purge cached data and update information about partition table type. Signed-off-by: Roman Stratiienko

fastboot: add command to select the eMMC boot configuration

2021-02-07T18:22:55Z

Add command oem bootbus which executes the command ``mmc bootbus `` on the current fastboot mmc device ( = CONFIG_FASTBOOT_FLASH_MMC_DEV) to set the eMMC boot configuration on first update, with = boot_bus_width reset_boot_bus_width boot_mode $> fastboot oem bootbus: Signed-off-by: Patrick Delaunay

fastboot: add command to select the default emmc hwpart for boot

2021-02-07T18:22:55Z
Add fastboot command oem partconf which executes the command ``mmc partconf 0`` on the current mmc device to configure the eMMC boot partition with : boot_ack boot_partition, so the command is: $> fastboot oem partconf: The partition_access argument is forced to 0 (userdata) Signed-off-by: Patrick Delaunay [lukma - Kconfig adjustments after merging this patch]

fastboot: mmc: extend flash/erase for both emmc hwpart 1 and 2

2021-02-07T18:22:55Z
Update the code and the configs for eMMC boot and userdata partitions acces - FASTBOOT_MMC_BOOT_SUPPORT: boot partition 1 and 2 (erase/write) - FASTBOOT_MMC_BOOT1_NAME: boot partition 1, default name="mmc0boot0" - FASTBOOT_MMC_BOOT2_NAME: boot partition 2, default name="mmc0boot1" This patch also removes the unnecessary dependency with ARCH_MEDIATEK and EFI_PARTITION.

fastboot: mmc: Add CONFIG_FASTBOOT_MMC_USER_SUPPORT

2021-02-07T18:22:55Z
Split userdata and boot partition support for eMMC update and correct the description (update is supported). The new configuration CONFIG_FASTBOOT_MMC_USER_SUPPORT allows to activate support of userdata partition update, based on target name=CONFIG_FASTBOOT_MMC_USER_NAME This patch also removes the unnecessary dependency with ARCH_MEDIATEK and EFI_PARTITION.

fastboot: Implement generic fastboot_set_reboot_flag

2021-02-07T18:22:54Z
It is possible to implement fastboot_set_reboot_flag in a generic way if BCB commands are turned on for a target. Using bcb_set_reboot_reason allows to do this by simply passing string with correct reboot reason that should be handled during next boot process. If BCB are turned off, then bcb_set_reboot_reason would simply return error, so it won't introduce any new behaviour for such targets. Signed-off-by: Roman Kovalivskyi

Revert "fastboot: Add default fastboot_set_reboot_flag implementation"

2021-02-07T18:22:54Z
This reverts commit 0ebf9842e56c5b8cb7cb1f990bb452cc14af6225. Current generic implementation of fastboot_set_reboot_flag is somewhat messy and requires some additional configuration option to be enabled besides CMD_BCB, so it reverts that implementtion in order to bring a new cleaner one. Next commit introduces new generic implementation of fastboot_set_reboot_flag. Signed-off-by: Roman Kovalivskyi

disk: dos: rename write_mbr_partition to write_mbr_sector

2021-01-15T19:38:00Z
write_mbr_partition() function name is a bit misleading, so rename it to write_mbr_sector(). This is a preparation for adding code for writing a complete MBR partition layout. Signed-off-by: Marek Szyprowski

fastboot: getvar: fix partition-size return value

2020-09-01T12:47:43Z
The size returned by 'getvar partition-size' should be in bytes, not in blocks as fastboot uses that value to generate empty partition when running format [1]. Note that the function was already returning the proper size in bytes for NAND devices (see struct part_info details).

fastboot: Add default fastboot_set_reboot_flag implementation

2020-09-01T12:47:43Z
Default implementation of fastboot_set_reboot_flag function that depends on "bcb" commands could be used in general case if there are no need to make any platform-specific implementation, otherwise it could be disabled via Kconfig option FASTBOOT_USE_BCB_SET_REBOOT_FLAG. Please note that FASTBOOT_USE_BCB_SET_REBOOT_FLAG is mutually exclusive with some platforms which already have their own implementation of this function. Signed-off-by: Roman Kovalivskyi
