To build RAMBOOT, replace this section the main Makefile

pcm030_RAMBOOT_config \
pcm030_LOWBOOT_config: unconfig
@ >include/config.h

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
