Hello,

I am not able to figure out the content of register r4 in the given code snippet.

I also wanted to know the significance of the address 0x 0F010000 got from the line "lwz     r4, 0(r3)".

 

boot_cold:

#if defined(CONFIG_MPC8260ADS)

            lis         r3, CFG_DEFAULT_IMMR@h

            nop

            lwz       r4, 0(r3)

            nop

            rlwinm  r4, r4, 0, 8, 5

            nop

            oris       r4, r4, 0x0200

            nop

            stw       r4, 0(r3)

            nop

 

Thanks & Warm Regards,

Prathima.
