The Intrinsyc CerfBoard is a StrongARM 1110-based computer on a board
that measures approximately 2" square. It includes an Ethernet
controller, an RS232-compatible serial port, a USB function port, and
one CompactFlash+ slot on the back. Pictures can be found at the
Intrinsyc website, http://www.intrinsyc.com.

This document describes the support in the Linux kernel for the
Intrinsyc CerfBoard as of version 2.4.0-test4-np1.

Supported in this version:
   - CompactFlash+ slot (select PCMCIA in General Setup and any options
     that may be required)
   - Onboard Crystal CS8900 Ethernet controller (Cerf CS8900A support in
     Network Devices)
   - Serial ports with a serial console (hardcoded to 38400 8N1)

Not supported in this version (yet):
   - LCD driver/touchscreen interface
   - UDC (a driver exists right now, but is unstable and slow and only
     works with the Linux USB)

In order to get this kernel onto your Cerf, you need a server that runs
both BOOTP and TFTP. Detailed instructions should have come with your
evaluation kit on how to use the bootloader. This series of commands
will suffice:

   make cerf_config
   make xconfig
   make dep
   make zImage
   cp arch/arm/boot/zImage <TFTP directory>

The default config uses a 4MB RAM disk located at 0xc0500000 as root.
Setting the board to mount root from a NFS partition works, too.
