Hello!
This series adds support for the mtdblock 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 mtd 0 part_name
Tested only on SPI NAND, so bind is made only for SPI NAND drivers.
Changes V1 -> V2 [1]:
- Drop patch [2].
- Add warning if bind NAND mtdblock device.
- Move documentation of mtdblock implementation from commit message to the source code.
- Remove __maybe_unused from mtd partition functions description.
- Use blk_enabled() instead of #ifdefs.
Changes V2 -> V3 [2]:
- Rebased over [3].
- Rename mtd_bread/bwrite -> mtd_blk_read/write.
- Fix GPL-2.0 license short name definiton in headers.
- Add empty line after MTD_ENTRY_NUMBERS define.
