- Restart the work on the AVR port ASAP.

- Look into importing or implementing a TCP/IP stack and a File System.

- Start the work on a Cortex-M3 port as soon GCC 4.3.0 will be released.
|

- Evaluate other architectures for a possible ChibiOS/RT port.

*** 0.5.5 ***

- Reorganized the code of the two ARM7 ports, now all the common ARM7 code

is in ./ports/ARM7. This will make maintenance and new ARM7 ports much

easier.
