#ifndef __CONFIG_H
#define __CONFIG_H
/*
* Define this to make U-Boot skip low level initialization when loaded
* by initial bootloader. 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...
