Sean Anderson de1728ce4c fastboot: Allow u-boot-style partitions
This adds support for partitions of the form "dev.hwpart:part" and
"dev#partname". This allows one to flash to eMMC boot partitions without
having to use CONFIG_FASTBOOT_MMC_BOOT1_SUPPORT. It also allows one to
flash to an entire device without needing CONFIG_FASTBOOT_MMC_USER_NAME.
Lastly, one can also flash MMC devices other than
CONFIG_FASTBOOT_FLASH_MMC_DEV.

Because devices can be specified explicitly, CONFIG_FASTBOOT_FLASH_MMC_DEV
is used only when necessary for existing functionality. For those cases,
fastboot_mmc_get_dev has been added as a helper function. This allows

There should be no conflicts with the existing system, but just in case, I
have ordered detection of these names after all existing names.

The fastboot_mmc_part test has been updated for these new names.

Sean Anderson f3cf964f2d fastboot: Remove mmcpart argument from raw_part_get_info_by_name
The only thing mmcpart was used for was to pass to blk_dselect_hwpart.
This calls blk_dselect_hwpart directly from raw_part_get_info_by_name. The
error handling is dropped, but it is reintroduced in the next commit
(albeit less specificly).

Roman Stratiienko adb5daf090 fastboot: reinit partition after storing GPT or MBR
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

Patrick Delaunay 3acbc7b2aa fastboot: mmc: extend flash/erase for both emmc hwpart 1 and 2
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.

Filip Brozovic a17c0cb85e fastboot: Support defining raw partitions without a partition table
Add support for defining raw fastboot partitions in eMMC by specifying
the offset and size in an environment variable. Optionally, the eMMC
hardware partition number may also be specified.

This makes it possible to e.g. update only part of the eMMC boot
partition, instead of having to write the entire partition.
