Changes in v4: - create defconfig by 'make savedefconfig' - drop explicit SYS_BAUDRATE_TABLE in favor of default one
Changes in v3: - drop SKIP_LOWLEVEL_INIT, GBL_DATA_OFFSET from config header - move CMD_MEMTEST, CMD_MEMINFO to defconfig - increase SYS_MALLOC_F_LEN to 0x600 - use auto-generated defconfig - no hand edit
Changes in v2: - move CONFIG_SYS_TEXT_BASE (from board/*/config.mk) to include/configs/<board>.h
