[U-Boot] [PATCH v4 0/5] Add NAND support to DFU, enable for am335x_evm

[Tom Rini]

This series adds DFU support to NAND and was started by Pantelis.  The
NAND changes have been compile-tested on all ARM and PowerPC targets and
run-time tested on ARM.  DFU itself has been tested, for NAND, on
am335x_evm.

For practical reasons, this series depends on Pantelis' previous series
of generic DFU changes.  Lukasz and I are discussing how to handle a few
changes there since one of them breaks file writing.

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

Pantelis Antoniou (2):
  dfu: NAND specific routines for DFU operation
  am335x_evm: Enable DFU for NAND and MMC, provide example alt_info for
    both

Tom Rini (3):
  nand: Extend nand_(read|write)_skip_bad with *actual and limit
    parameters
  cmd_nand.c: Fix CONFIG_CMD_NAND_YAFFS
  am335x_evm: Add CONFIG_CMD_MTDPARTS and relevant defaults
