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 2KiB. I'll hook up a BDI2000 and see if that helps.
