The mpc8xx restart consists in clearing the ME bit in MSR register to cause checkstop on machine check and then accessing an invalid location. I don't know if this causes a SRESET or HRESET and if the GPIO will be preserved or not. I know that PDDAT, PDDIR and the like are preserved with SRESET. Bye. P.S: Please don't post html messages! Do you know me? I see that you greeted me in your mail. _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
