Hi,

I went through "cpu/arm920t/start.S" file and found that this is what this
patch is doing. 

This patch places the entire cpu_init_crit function definition inside ifndef
same as in arm920t/start.S.

Sorry if i havent understood you.

Present cpu/arm926ejs/start.S

_start_armboot:
	.word start_armboot

                                            -----> This is where i have
placed #ifndef CONFIG_SKIP_LOWLEVEL_INIT 
/*
 *************************************************************************
 *
 * CPU_init_critical registers
 *
 * setup important registers
 * setup memory timing
 *
 *************************************************************************
 */


cpu_init_crit:
	/*
	 * flush v4 I/D caches
	 */
	mov	r0, 

<snip>
<snip>
<snip>
<snip>


	bl	lowlevel_init	/* go setup pll,mux,memory */
	mov	lr, ip		/* restore link */
	mov	pc, lr		/* back to my caller */
/*                                                                                               
----> here is the #endif 
 *************************************************************************
 *
 * Interrupt handling
 *
 *************************************************************************
 */
