BSP for the BSVC 68000 simulator. This is definitely under construction.
The initialization/setup script for BSVC is the part that likely needs
work. I have written the timer based on the timer sample included with
bsvc 2.1.
At this point, hello does not even print.

[The erc32 console driver can operate in either polled or interrupt mode.
Under the simulator (especially when FAST_UART is defined), polled seems to operate
better. It is common for a task to print a line (like the end of test message) and
then exit. In this case, the program returns control to the simulator command line
before the program has even queued the output to the uart. Thus sis has no chance
of getting the data out.])
