| |
Hi,
I'm developing some drivers for the AU1000 under Mountain Vista's 2.4.17 sherman release. The AU1000 is a MIPS based SOC with a 36 bit internal address bus and a 32 bit MIPS cpu. According to the documentation the MIPS' TLB is able to map 32 bit virtual addresses to 36 bit physical addresses, however I cannot figure out how to get Linux to set this up. I've looked at ioremap which only takes unsigned long (32bits) as an argument to assign a virtual address. Is there another way?
thanks
Padraig
