This series does a few things. I've updated Pantelis Antoniou's patch that allows for transfering of files larger than 4MiB to still allow for filesystem writes to work. I also document the existing DFU CONFIG options, and then the new options this series adds. Then we update nand_(read|write)_skip_bad so that we can add DFU support for NAND (started by Pantelis). Finally, we enable all of this for am335x_evm. This series has been compile-tested on all ARM and PowerPC targets and run-time tested on am335x_evm for NAND and MMC and eMMC.
This series depends on u-boot-usb/master but with a09f955 removed (as we replace that patch here).
-- Tom
Changes in v6: - Correct the check for attempting to write out of bounds on RAW MMC. - Pass correct buffer when reading a file from MMC. - Drop 1 line helper functions that were called only twice in dfu_mmc.c - Remove offset from MMC file ops as it was unused. - Fix checkpatch new checkpatch warnings - Update dfu_nand.c based on Scott's feedback
Changes in v5: - New patch to document existing DFU CONFIG options - Rework Pantelis' "dfu: Support larger than memory transfers" to not break filesystem writing - New patch to re-align defines in <dfu.h> - Document CONFIG_DFU_NAND in README - Add RAW MMC examples to include/configs/am335x_evm.h
Changes in v4: - Further reword nand_util.c comments, from Scott - In nand_write_skip_bad make sure *actual is 0 for YAFFS2 errors too, reminded by Scott. - In cmd_nand.c don't drop the size is less than maxsize check in arg_off_size as other nand functions need this still (Scott). - Add patch to fix CONFIG_CMD_NAND_YAFFS
Changes in v3: - Reworked skip_check_len changes to just add accounting for *used to the logic. - Allow for actual to be NULL in nand_(read|write)_skip_bad, only DFU calls this with a non-NULL parameter. Make sure the comments for both functions explain the parameters and their behavior. - Other style changes requested by Scott. - As nand_(write|read)_skip_bad passes back just a used length now. - Rework logic in nand_block_op for nand_(read|write)_skip_bad returning just a size for actual used length. - Remove unused externs from drivers/dfu/dfu_nand.c - Fix checkpatch.pl warnings in include/configs/am335x_evm.h
Changes in v2: - NAND skip_check_len changes reworked to allow nand_(read|write)_skip_bad to return this information to the caller. - nand_block_op calls nand_(read|write)_skip_bad directly. - Bugfix in dfu_nand to make sure we set dfu->skip_bad to 0 on each iteration. - Add CONFIG_CMD_MTDPARTS and relevant information to am335x_evm - Enable DFU for NAND and MMC, set dfu_alt_info_(nand|mmc) as examples for both in am335x_evm.h - Increase CONFIG_SYS_MAXARGS due to hush parsing bugs that would otherwise prevent 'setenv dfu_alt_info ${dfu_alt_info_nand}' on am335x_evm
