Sounds reasonable. Other than wilful perversity I can't think
of any reason why a particular port might want to map the CSRs
at a different address to that which the others use, but I agree
that as a matter of principle it probably ought to be done the
way you suggest. :-)
In the co285 arch the kernel is mapped at 0x60000000, the address range
from 0x80000000 to 0xffffffff is used to access the PCI bus. I could of
course map the CSRs into this address range and then map some part of
the PCI space somewhere else, but I hope you agree with me that this
would be far more perverse :-)
Mark.
