Not required by NAND U-Boot version but IS - * required for a NOR version used to burn the real NOR U-Boot into - * NOR Flash. NAND and NOR support for DaVinci chips is mutually exclusive - * so it is NOT possible to build a U-Boot with both NAND and NOR routines. - * NOR U-Boot is loaded directly from Flash so it must perform all the - * low level initialization itself. NAND version is loaded by an initial - * bootloader (UBL in TI-ese) that performs such an initialization so it's - * skipped in NAND version. The third DaVinci boot mode loads a bootloader - * via UART0 and that bootloader in turn loads and runs U-Boot (or whatever) - * performing low level init prior to loading. All that means we can NOT use - * NAND version to put U-Boot into NOR because it doesn't have NOR support and - * we can NOT use NOR version because it performs low level initialization - * effectively destroying itself in DDR memory. That's why a separate NOR - * version with this define is needed. It is loaded via UART, then one uses - * it to somehow download a proper NOR version built WITHOUT this define to - * RAM (tftp?) and burn it to NOR Flash. I would be probably able to squeeze - * NOR support into the initial bootloader so it won't be needed but DaVinci - * static RAM might be too small for this (I have something like 2Kbytes left - * as of now, without NOR support) so this might've not happened... - * - */ - -/*===================*/ -/* SoC Configuration */ -/*===================*/ -#define CONFIG_ARM926EJS /* arm926ejs CPU core */ -#define CONFIG_MX28 /* STMP378x SoC */ -#define CONFIG_SYS_CLK_FREQ 120000000 /* Arm Clock frequency */ -#define CONFIG_USE_TIMER0 /* use timer 0 */ -#define CONFIG_SYS_HZ 1000 /* Ticks per second */ -/*=============*/ -/* Memory Info */ -/*=============*/ -#define CONFIG_SYS_MALLOC_LEN (0x10000 + 128*1024) /* malloc() len */ -#define CONFIG_SYS_GBL_DATA_SIZE 128 /* reserved for initial data */ -#define CONFIG_SYS_MEMTEST_START 0x40000000 /* memtest start address */ -#define CONFIG_SYS_MEMTEST_END 0x40400000 /* 16MB RAM test */ -#define CONFIG_NR_DRAM_BANKS 1 /* we have 1 bank of DRAM */ -#define CONFIG_STACKSIZE (256*1024) /* regular stack */ -#define PHYS_SDRAM_1 0x40000000 /* mDDR Start */ -#define PHYS_SDRAM_1_SIZE 0x08000000 /* mDDR size 32MB */ - -/*====================*/ -/* Serial Driver info */ -/*====================*/ -#define CONFIG_DBGUART_CLK 24000000 -#define CONFIG_BAUDRATE 115200 /* Default baud rate */ -#define CONFIG_SYS_BAUDRATE_TABLE { 9600, 19200, 38400, 57600, 115200 } - -/*====================*/ -/* SPI Driver info */ -/*====================*/ -#define CONFIG_SSP_CLK 48000000 -#define CONFIG_SPI_CLK 3000000 -#define CONFIG_SPI_SSP1 -#undef CONFIG_SPI_SSP2 - -/*=====================*/ -/* Flash & Environment */ -/*=====================*/ -#define CONFIG_SYS_NO_FLASH /* Flash is not supported */ -#define CONFIG_ENV_IS_NOWHERE /* Store ENV in memory only */ - - -/* ROM loads UBOOT into DRAM */ -#define CONFIG_SKIP_RELOCATE_UBOOT - - -/*==============================*/ -/* U-Boot general configuration */ -/*==============================*/ -#define CONFIG_BOOTDELAY 2 -#define CONFIG_BOOTFILE "uImage" /* Boot file name */ -#define CONFIG_SYS_PROMPT "MX28 U-Boot > " -#define CONFIG_SYS_CBSIZE 1024 /* Console I/O buffer size */ -#define CONFIG_SYS_PBSIZE \ - (CONFIG_SYS_CBSIZE + sizeof(CONFIG_SYS_PROMPT) + 16) - /* Print buffer size */ -#define CONFIG_SYS_MAXARGS 16 /* Max number of command args */ -#define CONFIG_SYS_BARGSIZE CONFIG_SYS_CBSIZE - /* Boot argument buffer size */ -#define CONFIG_VERSION_VARIABLE /* U-BOOT version */ -#define CONFIG_AUTO_COMPLETE /* Command auto complete */ -#define CONFIG_CMDLINE_EDITING /* Command history etc */ -#define CONFIG_VERSION_VARIABLE -#define CONFIG_AUTO_COMPLETE /* Won't work with hush so far, may be later */ -#define CFG_HUSH_PARSER -#define CFG_PROMPT_HUSH_PS2 "> " -#define CONFIG_CMDLINE_EDITING -#define CFG_LONGHELP -#define CONFIG_CRC32_VERIFY -#define CONFIG_MX_CYCLIC - -/* - * Boot Linux - */ -#define LINUX_BOOT_PARAM_ADDR 0x40000100 -#define CONFIG_CMDLINE_TAG -#define CONFIG_SETUP_MEMORY_TAGS -#define CONFIG_BOOTARGS "console=ttyAM0,115200n8 " -#define CONFIG_BOOTCOMMAND "run bootcmd_net" -#define CONFIG_LOADADDR 0x42000000 -#define CONFIG_SYS_LOAD_ADDR CONFIG_LOADADDR - -/* - * Extra Environments - */ -#define CONFIG_EXTRA_ENV_SETTINGS \ - "nfsroot=/data/rootfs_home/rootfs\0" \ - "bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs " \ - "ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp\0" \ - "bootcmd_net=run bootargs_nfs;
