We should just get rid of
dev->rmem_end
dev->rmem_start
dev->mem_start
dev->mem_end
dev->dma
Most of these are used only in obsolete ISA drivers, which really should
keep them in a local structure. We should replace at least two of the
values with, say, "param1" and "param2" so that LILO parameters still work.
We should retain
dev->irq
dev->base_addr
but change the latter documentation to /* I/O or memory address */
There should not be provisions for a user-level program to modify the irq or
base_addr, since these should never be changed with PCI, USB, CardBus, etc.
Changing the param1..paramN values should be permitted from a user-level
program.
