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_MX23 /* MX23 SoC */ +#define CONFIG_MX23_EVK /* MX23 EVK 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 "MX23 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 */ |
