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 SONATA_BOARD #define CONFIG_SYS_NAND_SMALLPAGE #define CONFIG_SYS_USE_NOR /*===================*/ /* SoC Configuration */ /*===================*/ #define CONFIG_ARM926EJS /* arm926ejs CPU core */ #define CONFIG_SYS_CLK_FREQ 297000000 /* Arm Clock frequency */ #define CONFIG_SYS_TIMERBASE 0x01c21400 /* use timer 0 */ #define CONFIG_SYS_HZ_CLOCK 27000000 /* Timer Input clock freq */ #define CONFIG_SYS_HZ 1000 /*====================================================*/ /* EEPROM definitions for Atmel 24C256BN SEEPROM chip */ /* on Sonata/DV_EVM board.
