Initial work on a port to the Logik DAX 1GB MP3/DAB player. The bootloader build compiles and runs (but only displays some debugging info), and the LCD and ADC drivers are working. Two different bootloader builds are possible: 1) The default build is just a test application for uploading to the device via tcctool; 2) Adding -DTCCBOOT to EXTRA_DEFINES in the build directory Makefile will compile the bootloader so that it can be appended to the end of the original firmware and installed on the device, dual-booting. This commit also includes some work by Hein-Pieter van Braam on a port to the iAudio 7, but that doesn't build yet. A large part of these ports will be generic to all TCC77x devices - see the TelechipsInfo wiki page for some other devices with this CPU. NOTE: Compiling these builds requires an arm-elf-gcc with armv5 support - the current version of rockboxdev.sh compiles such a gcc.
