That option should be in the defconfig already - was it not?
I should just hardcode that option and get it over with.

Subject: RE: No PCI memory response
Hi -
I'm certainly seeing what looks like random reads...however, is the
static bus controller actually implicated in PCI bus operations? The
product brief for the Au1100 doesn't mention PCI, so I'm not sure that
we're looking at the same problem.
Thanks,
Gill

Can anyone help? We're trying to talk to a RealTek RTL8139 device
across the PCI bus, and, although linux can access configuration
registers on the device, it does not access memory space correctly,
and we are unable to read back any sensible values from the RTL8139
registers.
We are using the latest 2.6 linux on an Alchemy DB1550 board.
Random reads, discarded data after writing? I had the same problem and
solved
it by simply configuring the static bus controller of my Au1100 properly
(of
which before I didn't even know it existed...).
