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 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
