This bit ?

#ifdef CONFIG_NOR_BOOT
	asm("stmfd      sp!, {r2 - r4}");
	asm("movw       r4, #0x8A4");
	asm("movw       r3, #0x44E1");
	asm("orr        r4, r4, r3, lsl #16");
	asm("mov        r2, #9");
	asm("mov        r3, #8");
	asm("gpmc_mux:  str     r2, [r4], #4");
	asm("subs       r3, r3, #1");
	asm("bne        gpmc_mux");
	asm("ldmfd      sp!, {r2 - r4}");
#endif

Yes ... :-)
