Hello!
This series adds support for the UBI block device, which allows to read/write data block by block. For example, it can now be used for BCB or Android AB command:
$ bcb load ubi 0 part_name
Tested only on SPI NAND, so bind is made only for SPI NAND drivers. Can be used with mtdblock device [1].
---
Changes V1 -> V2 [2]:
- Rebased over mtdblock v2 patchset [3]. - Compile UBI partitions support only if CONFIG_BLK option is enabled.
Changes V2 -> V3 [4]:
- Fix build warnings: use LBAF printf format string for lbaint_t types.
Changes V3 -> V4 [5]:
- Rebased over u-boot/master. - Fix build errors and warnings if CONFIG_BLK isn't enabled. - Fix failed tests in cases is ubiblock device isn't binded.
Changes V4 -> V5 [6]:
- Rebased over u-boot/master. - Fix build errors when CONFIG_MTD and CONFIG_MTD_UBI isn't enabled. - Use auto blk device devnum generation when call blk_create_devicef (pass -1 parameter instead of dev_seq(dev)).
Changes V5 -> V6 [7]:
- Rebased over u-boot/master. - Introduce CONFIG_UBI_BLOCK which is disabled by default. - Fix undefined reference to `__aeabi_ldivmod' compiler error for 32-bit ARM targets.
