Linux booting problem MPC7457 based board with U-boot 1.1.4 and Linux 2.6.12.6

[Mustafa Cayır]

Hi all,

I have a custom MPC7457 based board which has been running U-boot 1.1.4. I am trying to port Linux 2.6.12.6 .

When booting, Linux hangs when calling "call_setup_cpu" function.

arch\ppc\kernel\head.S

/*
 * Call setup_cpu for CPU 0 and initialize 6xx Idle
 */
	bl	reloc_offset
	li	r24,0			/* cpu# */
	bl	call_setup_cpu		/* Call setup_cpu for this CPU */


Regards.
