I used the CLKO pin to track down how far the booting from NAND gets.
It hangs in nand_imx.c:wait_op_done, after having sent the first
NAND_CMD_READ0 command from nand_imx.c:imx_nand_load_image. (Weird,
since that routine has a timeout)
So SDRAM init appears to be ok; I also checked barebox.S, and
everything needed to complete imx_nand_load_image is in the first
I'll hook up a BDI2000 and see if that helps.
