[U-Boot-Users] debugging U-boot with GDB on a Au1550

I have U-boot running on a Au1550 platform. I have verified that re-location to RAM works but the system is crashing somewhere in board_init_r. I would like to debug this with GDB and a BDI2000, but am running into a few issues. U-boot for this platform is linked to 0xbfc00000 (the ROM reset vector). This is not what I am used to as most ARM platforms are linked to the RAM location. After U-boot is relocated to RAM, how do I tell GDB what the new link address is (0x80fdc000 in this case)?

Thanks, Cliff
