If your board usually boots from NOR, then it is connected to the NOR FLASH chip. The AMCC/APM evaluation boards have a jumper to toggle this chip-select between NAND and NOR. If your custom board doesn't have such a means to toggle the CS0 then you have no chance to boot from NAND. Another idea would be to build a rambooting U-Boot target for your board. This is supported for Sequoia. But not for Canyonlands. You might want to take a look at that. Otherwise you need to burn the U-Boot image into your NOR FLASH and just hope that it works. A JTAG debugger would be handy if it doesn't work though.
