Hardware design guide...

I am working closely with a hardware engineer to design an
embedded I/O baord what will be connected to an ARM procesor
board (CompuLab's ARMCore - uses PXA255).
The I/O board will have some Flash memory on it, and at this stage
we are looking at either:
E28F128 - Intel; or
M29W320 - ST Thomson
Are there any resources/recommendations
/instructions on the best
way to 'wire this up'? eg. A hardware design guide?
The MTD driver interface is very nicely modular (thanks everyone),
and I want the hardware to fit into this model. What should be
avoided hardware wise, so that we can make best use of this API.
(I don't want to have to hack source just because we made some
assumption that doesn't hold..)
The current plan is to hook the chip onto the local and drive
the control lines via a PLD controlled via a port addresses.
eg. Chip enable, VPEN(VPP), and (more importantly) BusyBit.
Also, on a related note, I'm was looking through the MTD source code,
trying to get a handle on the above questions, but couldn't find where
the parameters for the chipsets were set... does such a thing exist?
