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... + * +#define CONFIG_NOR_UART_BOOT + */ + +/*=======*/ +/* Board */ +/*=======*/ +#define DV_EVM +#define CFG_NAND_SMALLPAGE +#define CFG_USE_NOR +/*===================*/ +/* SoC Configuration */ +/*===================*/ +#define CONFIG_ARM926EJS /* arm926ejs CPU core */ +#define CONFIG_SYS_CLK_FREQ 297000000 /* Arm Clock frequency */ +#define CFG_TIMERBASE 0x01c21400 /* use timer 0 */ +#define CFG_HZ_CLOCK 27000000 /* Timer Input clock freq */ +#define CFG_HZ 1000 +/*====================================================*/ +/* EEPROM definitions for Atmel 24C256BN SEEPROM chip */ +/* on Sonata/DV_EVM board.
