| /* |
| * 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... |
