I'd rather stick with the common code and not proliferate start.S
versions. The main bug right now is that r9 is not zero'd for the SPL
case causing a random offset to be added.

But more consolidation is possible:

	ldr	r0, _board_init_r_ofs	ldr	r1, _TEXT_BASE	add	lr, r0, r1	add	lr,
lr, r9	/* setup parameters for board_init_r */	mov	r0, r5		/* gd_t
*/	mov	r1, r6		/* dest_addr */	/* jump to it ... */	mov	pc, lr
_board_init_r_ofs:#ifdef CONFIG_NAND_SPL
	.word nand_boot - _start
#else
	.word board_init_r - _start#endif

Even more if nand_boot is wrapped and renamed board_init_r().
