[Arm-netbook] adafruit spi lcd hx8357d and arduino uno

[Luke Kenneth Casson Leighton]

.... arrived today, and were up and running, working perfectly, in
under 15 minutes:
http://git.rhombus-tech.net/?p=eoma-firmware.git;a=tree;f=eoma68/arduino_uno_spi_test

i used a makefile that was easily found with a google search "debian
arduino uno makefile", followed the instructions _in_ the makefile,
created a blink test, ran it, ran "make upload" and it worked.  total
time: well under 3 minutes.  next was the SPI-based LCD, soldering
took a few minutes, copying the library files into the main directory
a few more - done.

i've now modified the adafruit source code so that it can do 9-bit SPI
bit-banging, by setting "IM1=0" (shorting that to ground) and i'm now
in a position to begin two-way testing of the adafruit LCD with an
STM32F072, and the yunlea HX8357D LCD with the arduino uno.

this is a heck of a lot quicker than messing about with both unknown
hardware and unknown software.
