-* PURPOSE:
-*
-* This implements a driver for using the robostix from the gumstix
-*
-* Initially, this contains the required support to emulate enough of the
-* parallel port interface to allow avrdude to program the ATMega128.

-* The following shows the mapping of the SPI port for the gumstix:

-* NSSPCLK 81 out ATM_SCK Acts as SCK for SPI use
-* NSSPFRAME 82 out ATM_SS Acts as SS for SPI use
-* X_MOSI 83 out ATM_MOSI Acts as MOSI for SPI use
-* X_MISO 84 in ATM_MISO Acts as MISO for SPI use
-*
-* On the verdex, the mapping for the SPI port is slightly different:
-*
-* SSPCLK2 19 out ATM_SCK Acts as SCK for SPI use
-* SSPSFRM2 14 out ATM_SS Acts as SS for SPI use
