Subject: 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.
