Not required by NAND U-Boot version but IS 26 * required for a NOR version used to burn the real NOR U-Boot into 27 * NOR Flash. NAND and NOR support for DaVinci chips is mutually exclusive 28 * so it is NOT possible to build a U-Boot with both NAND and NOR routines. 29 * NOR U-Boot is loaded directly from Flash so it must perform all the 30 * low level initialization itself. NAND version is loaded by an initial 31 * bootloader (UBL in TI-ese) that performs such an initialization so it's 32 * skipped in NAND version. The third DaVinci boot mode loads a bootloader 33 * via UART0 and that bootloader in turn loads and runs U-Boot (or whatever) 34 * performing low level init prior to loading. All that means we can NOT use 35 * NAND version to put U-Boot into NOR because it doesn't have NOR support and 36 * we can NOT use NOR version because it performs low level initialization 37 * effectively destroying itself in DDR memory. That's why a separate NOR 38 * version with this define is needed. It is loaded via UART, then one uses 39 * it to somehow download a proper NOR version built WITHOUT this define to 40 * RAM (tftp?) and burn it to NOR Flash. I would be probably able to squeeze 41 * NOR support into the initial bootloader so it won't be needed but DaVinci 42 * static RAM might be too small for this (I have something like 2Kbytes left 43 * as of now, without NOR support) so this might've not happened... 44 * 45#define CONFIG_NOR_UART_BOOT 46 */ 47 48/*=======*/ 49/* Board */ 50/*=======*/ 51#define DV_EVM 52#define CONFIG_SYS_NAND_SMALLPAGE 53#define CONFIG_SYS_USE_NAND 54/*===================*/ 55/* SoC Configuration */ 56/*===================*/ 57#define CONFIG_ARM926EJS /* arm926ejs CPU core */ 58#define CONFIG_SYS_TIMERBASE 0x01c21400 /* use timer 0 */ 59#define CONFIG_SYS_HZ_CLOCK 27000000 /* Timer Input clock freq */ 60#define CONFIG_SYS_HZ 1000 61#define CONFIG_SOC_DM644X 62/*====================================================*/ 63/* EEPROM definitions for Atmel 24C256BN SEEPROM chip */ 64/* on Sonata/DV_EVM board.
