The hashtable.S defined: Hash_base = 0xc0180000. How and where
was this address (range) mapping setup ? in BAT or page mode ?
Aother question is when code is running in exception context,
does MSR[IR] and MSR[DR] always turned on ?
Thanks.

I'm trying to port PPC Linux on a PPC 750 based CPU.
However, its page table logic has flaws so that I cannot use paging.
Can PPC Linux work without paging but using only BATs?
Does anyone have such experience?
