[U-Boot-Users] relocating from flash to ram on AT91RM9200DK
I'm using a custom board that was based off of the AT91RM9200DK/EK. Right now we're booting from parallel flash using boot.bin (from Atmel), but I'd like to get rid of the need for it. I assume I can use CONFIG_SKIP_RELOCATE_UBOOT and CONFIG_SKIP_LOWLEVEL_INIT to do this.
What do I need to set TEXT_BASE to for this to work?

This depends on your chosen memory map, i. e. base address and size of your RAM and intended location of U-Boot in it.

Assuming I'm using the AT91RM9200DK, can you provide an example of a working configuration. Shouldn't the default configuration work with CONFIG_SKIP_RELOCATE_UBOOT and CONFIG_SKIP_LOWLEVEL_INIT undefined?

Why don't you just look at the settings of all the other AT91RM9200 boards (including the AT91RM9200DK, which works fine as is)?
