The DM6446 does not build due to the ARM relocation patch. Also the board does not build in the NOR mode. Changed default to NAND to ensure no build failure. While at it removed CONFIG_CMD_KGDB Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

/*
|
|
* 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...
