Hi :
The following is the version I am using, it's pretty much same as
do_reset() code in u-boot -1.1.4 for m8260 target. However the machine

This is a random address which happens to be not mapped in the
specific board (MPC8260ADS.h). The
This way maybe can not work. when the MMU turn off,
the next instructions maybe can not be fetched if these instructions
didn't exist cache.
so it is possible these instruction can not executed.
Trying to jump to some boot rom address is IMHO always a bad

Hi :
I tried your approach last ight, (in fact I copied part of the
do_reboot() code from u-boot and put it in m8260_restart() function in
the kernel). The only difference is the first line,
volatile immap_t *immap = (immap_t *) IMAP_ADDR;
in my case it is
volatile immap_t * immap =
