... both are probably wrong, as the saying goes. I stumbled across this line in arch/mips/au1000/common/reset.c: au_writel(0x00, 0xb1900100); /* sys_pininputen */ However, 0xb1900100 is SYS_TRIOUTCLR, while SYS_PININPUTEN is 0xb1900110... Which one is right now? Also, does the switch statement in that file make sense at all? I mean is it possible to compile a kernel that runs on several Alchemy systems? Uli
