omap2_sdrc_get_params() should check to see if a board-*.c file has called omap2_init_common_hw() with a null pointer for the omap_sdrc_params argument, rather than attempting to dereference it. Otherwise, boot will fail after the "Reprogramming SDRC" boot message. Problem found by Peter Barada <[email protected]>.
