Why? I don't see much difference between EBUS and ISA and with the
memory API, the difference between PIO and MMIO is almost nonexistent
anyway.
Can you elaborate? Do you mean we just need to change the io_base?
Why wouldn't that work?
Because the PIO variant registers just 4 ports, whereas MMIO registers
the whole device (0x2000 bytes).
The sun4u machines use a slightly different modification of the ISA Mostek chip.
It has MMIO, 1968 as a base year and no IRQ line. Since it matches our m48t08,
I'll send a patch fixing it.
But it should be possible to change the base to match real HW, whatever it
is:
http://git.kernel.org/cgit/linux/kernel/git/davem/prtconfs.git/tree/ultra5#n273
Yes, I know where it is supposed to be, I'm just asking how to achieve
this best with our current tooling.
So NACK for the original patch.
Do you think it should be implemented as another device type?

As m48t59 devices can only be created with m48t59_init() or m48t59_init_isa(),
we know exactly which nvram types are required. Register only those three
types.
Remove .model and .size properties as they can be infered from nvram name.
Remove .io_base ISA address port as m48t59_init_isa() is always called with
ioport 0x74.
While this it indeed how it's currently called, this is wrong for the
sun4u emulation.
The isa (ebus) variant of the sun4u m48t59_init_isa() should be called
with a mem_base, not io_base.
Do you think it should be implemented as another device type?

Do you think it should be implemented as another device type? I don't know EBUS, but I think it should be implemented either as a completly new bus (1), or as a child of the ISA bus type (2). For 1), you'll need to add a another device type to be plugged on EBUS. For 2), I let experts answer :) In all cases, maybe the m48t59_init() wrapper is what you need? You can already give him a membase. Otherwise, you can maybe use sysbus_create_simple(m48t59), get the resulting MemoryRegion from the device, and add it in whatever MemoryRegion. Hervé
