Masahiro Yamada 93d4334f7f Add board MAINTAINERS files We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

Alternative SDRAM settings:

/* Settings for XLB = 99 MHz */

The board ships default with the environment in EEPROM
Moving the environment to flash can be more reliable

#define CONFIG_ENV_IS_IN_FLASH	1
#define CONFIG_ENV_ADDR		(CONFIG_SYS_FLASH_BASE + 0xfe0000)
#define CONFIG_ENV_SIZE		0x20000
#define CONFIG_ENV_SECT_SIZE	0x20000
