[U-Boot-Users] Debug from SDRAM

I have a new board(the chip is just being made) with flash on its local
bus, but the localbus-flash is not working. i modified the code on a few
key configs including CFG_RAMBOOT, CFG_ENV_IS_NOWHERE and
CFG_NO_FLASH(grep them in u-boot and find their use) to run U-Boot in
DDR directly. Of course you need use your debugger to initilize
DDR/SDRAM before you download U-Boot to it.

if you have a working flash, you really don't need to do so and it's
better to boot from flash and wait for U-Boot to configure your SDRAM
