To build RAMBOOT, replace this section the main Makefile

	@ >include/config.h
	@[ -z "$(findstring LOWBOOT_,$@)" ] || \

		  echo "... with LOWBOOT configuration" ; \
		}
	@[ -z "$(findstring RAMBOOT_,$@)" ] || \

			config.tmp ; \

				switched to 0xF0000000 !!!" ; \

Alternative SDRAM settings:

#define SDRAM_MODE	0x018D0000
#define SDRAM_EMODE	0x40090000
#define SDRAM_CONTROL	0x715f0f00
#define SDRAM_CONFIG1	0x73722930
#define SDRAM_CONFIG2	0x47770000

/* Settings for XLB = 99 MHz */
#define SDRAM_MODE	0x008D0000
#define SDRAM_EMODE	0x40090000
#define SDRAM_CONTROL	0x714b0f00
#define SDRAM_CONFIG1	0x63611730
#define SDRAM_CONFIG2	0x47670000

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
