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_STMP378X /* STMP378x SoC */ #define CONFIG_STMP378X_DEV /* STMP378x Development board */ #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 0x41000000 /* 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 0x02000000 /* mDDR size 32MB */ /*====================*/ /* Serial Driver info */ /*====================*/ #define CONFIG_STMP3XXX_DBGUART /* 378x debug UART */ #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 */ #define CONFIG_ENV_SIZE 0x20000 /*==============================*/ /* U-Boot general configuration */ /*==============================*/ #undef CONFIG_USE_IRQ /* No IRQ/FIQ in U-Boot */ #define CONFIG_MISC_INIT_R #define CONFIG_NETMASK 255.255.255.0 #define CONFIG_IPADDR 192.167.10.2 #define CONFIG_SERVERIP 192.167.10.1 #define CONFIG_BOOTDELAY 2 #define CONFIG_BOOTFILE "uImage" /* Boot file name */ #define CONFIG_SYS_PROMPT "stmp378x U-Boot > " /* Monitor Command Prompt */ #define CONFIG_SYS_CBSIZE 1024 /* Console I/O Buffer Size */ #define CONFIG_SYS_PBSIZE (CONFIG_SYS_CBSIZE+sizeof(CONFIG_SYS_PROMPT)+16) /* Print buffer sz */ #define CONFIG_SYS_MAXARGS 16 /* max number of command args */ #define CONFIG_SYS_BARGSIZE CONFIG_SYS_CBSIZE /* Boot Argument Buffer Size */ #define CONFIG_SYS_LOAD_ADDR 0x40400000 /* default Linux kernel load address */ #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 /*===================*/ /* Linux Information */ /*===================*/ #define LINUX_BOOT_PARAM_ADDR 0x40000100 #define CONFIG_CMDLINE_TAG #define CONFIG_SETUP_MEMORY_TAGS #define CONFIG_BOOTARGS "console=ttyAM0,115200n8 "\ "root=/dev/mtdblock1 rootfstype=jffs2 lcd_panel=lms350" #define CONFIG_BOOTCOMMAND "tftpboot ; bootm" /*=================*/ /* U-Boot commands */ /*=================*/ #include <config_cmd_default.h> #define CONFIG_CMD_ASKENV #define CONFIG_CMD_DHCP #define CONFIG_BOOTP_SUBNETMASK #define CONFIG_BOOTP_GATEWAY #define CONFIG_BOOTP_DNS #undef CONFIG_CMD_DIAG #define CONFIG_CMD_MII #define CONFIG_CMD_PING #define CONFIG_CMD_NET #define CONFIG_CMD_SAVES #undef CONFIG_CMD_IMLS /* Ethernet chip - select an alternative driver */ #define CONFIG_ENC28J60_ETH #define CONFIG_ENC28J60_ETH_SPI_BUS 0 #define CONFIG_ENC28J60_ETH_SPI_CS 0 #endif /* __CONFIG_H */
