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.

/*
Append a Rockbox bootloader to a Telechips original firmware file.
The first instruction in a TCC firmware file is always of the form:
ldr pc, [pc, #xxx]
where [pc, #xxx] is the entry point of the firmware - e.g. 0x20000020
mktccboot appends the Rockbox bootloader to the end of the original
firmware image and replaces the contents of [pc, #xxx] with the entry
point of our bootloader - i.e. the length of the original firmware plus
0x20000000.
It then stores the original entry point from [pc, #xxx] in a fixed
offset in the Rockbox boootloader, which is used by the bootloader to
dual-boot.
Finally, mktccboot corrects the length and CRCs in the main firmware
header, creating a new legal firmware file which can be installed on
the device.
