Message-Id: <1316066380-7397-9-git-send-email-hs@denx.de>

- changes for v2
  - use CONFIG_MACH_TYPE instead setting the MACH_TYPE in
    board specific code, as Igor Grinberg suggested.
  - add logversion=2 to default Environment
  - Fix typo CONFIG_AM1808_LOWLEVEL as Christian Riesch
    suggested.
  - Fix comment for PLL0 and PLL1 frequency and use PLLM = 18
    for PLL0 to get the 456 MHz as Christian Riesch commented.
    Also fix the DDR RAM timing according to the new settings
    from the PLL
  - add MMC support
  - enable USB PSC
  - correct default environment "key_cmd*" vars
  - added MAINTAINERS entry

For the pinmux configuration there is already code in
board/davinci/common/davinci_pinmux.c that is used by the boards in
board/davinci/da8xxevm. Would it make sense to move this file to
arch/arm/cpu/arm926ejs/davinci so you could use the same code on your
board instead of having these defines here?

Regards, Christian
