24 * Define this to make U-Boot skip low level initialization when loaded
25 * by initial bootloader. 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...
