Subject: am335x_evm: Enable DFU for NAND and MMC, provide example alt_infos
X-Git-Tag: v2013.04-rc3~13^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ef4e9fc6aae786eac839d989b0e647f8d2b530f4;p=kernel%2Fu-boot.git

am335x_evm: Enable DFU for NAND and MMC, provide example alt_infos

- Add CONFIG_DFU_NAND, CONFIG_DFU_MMC
- Set dfu_alt_info_nand, dfu_alt_info_emmc and dfu_alt_info_mmc to show
  working examples for those cases.
- Increase CONFIG_SYS_MAXARGS due to hush parsing bugs that would
  otherwise disallow 'setenv dfu_alt_info ${dfu_alt_info_nand}'.
- Enable CONFIG_FAT_WRITE to allow updating on MMC
