This essentially syncs up the bits that were left behind to rot from arm-xo-1.75.
This will allow us to support SPI on board without the OLPC security mechanism.
It is the only user and having to define it before loading lcd.fth sort of sucks.
This is a trivial rename. The cl4 word conditionalizes things that are specific to MMP3, not the just OLPC CL4 machine. Using the cl4 name outside OLPC would be misleading.
This adds support for using CForth on the MMP3-based Ariel board, as used in Dell Wyse 3020. It starts up on the small core and loads OFW in a manner equivalent to what is done on OLPC CL4. Among the differencies from CL4 are: diffrent DRAM, generally less hardware hooked to GPIOs (no special keys, etc.), different EC, and different display controller. The only UART that's routed to actual connector on board is UART3 on pins 51 and 52. The machine originally comes with proprietary "WLoader" firmware. Running Open Firmware on it would make it suck considerably less.
