We implemented console support (through serial port), for the current board types supported (Feroceon, using UART 16550).

Browse source 
We added a new ClockRate member to the ARM Board Block structure.
We now print out the FreeLDR header after initialization to give some output to the user that we are alive.
Started putting shared stuff in headers.
Fixed copy/paste leftovers from file headers (wrong file names, implementation details, author).
