[PATCH - v5] support for Embedian MXM-8x10

Fri Jan 22 03:10:45 EST 2010
This version of the patch has added support for our iControl platform, which is
based on the same MXM-8x10 module as the CAPC-7117 development board.
For the most part, it just reuses all the stuff in mxm8x10.c and adds support
for some CAN bus chips.
Patch is still against vanilla 2.6.33-rc4.
Would appreciate comments.
Thank you.
Regards,
Edwin Peer
