***
Message-Id: <1316066380-7397-9-git-send-email-hs at 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
