I am nearing useability on a new port to the Cirrus Logic EP93XX (ARM9) CPU's 
and the Technologic Systems TS-7200 single board computer.  Is there anything 
like a "new port checklist" as I near completion?  So far, I have drivers for 
the compact flash card (wdc), USB 1.1 (epohci), on-chip serial (epcom), and 
an isa driver for the PC/104 bus.   I've only been able to test serial 
(16550) expansion cards on the PC/104 bus.  The system clock uses the 64Hz 
RTC interrupt and microtime() uses a 983.04 KHz freerunning timer to acheive 
~1uS timing precision.

Remaining work includes the PLD watchdog timer, on-chip ethernet MAC, and I'd 
like to do something useful with the 8Mb onboard NOR flash chip though I'm 
not sure how or what yet.  The MAC uses a Micrel low-power PHY that also 
might need a driver.  The NetBSD port is currently capable of booting to 
onboard CF or a USB thumb drive.

About the TS-7200:

The TS-7200 is a mass-produced low-cost embedded board available from 
http://www.embeddedARM.com at $119 in qty, (or $149 qty 1) that includes a 
200Mhz ARM9 processor, 32MB SDRAM, 10/100 ethernet, USB1.1, 2 serial ports 
with RS485 option, PC/104 expansion bus, and a compact flash card socket.   
The board also contains DIO and ADC's, and support for text mode (Hitachi 
controller based) LCDs but I'm thinking those may be best utilized by 
user-space access to /dev/mem.  The board targets industrial embedded 
applications but is also useful as an "embedded server" for infrastructure 
"guts" applications requiring the high reliability and low seek times of 
solid state disks, low power (runs 10-20x longer than PC's on a regular UPS), 
long production lifetime for replacements, small size, quiet running, and 
inherent system reliability due to all soldered-on components with relatively 
small (compared to a x86 PC server) hardware complexity.
