All boot code tests can be run after setting the normal bb build 
environment variables and issuing the following command from
this directory:

  run_tests.pl -t tests -d <output_dir>

The directory specified by <output_dir> will be created if it
does not exist. It will contain the simulator initialization
files that were copied to the hw/chip/vsim directory for
external flash (psk.nand), internal virage read-only flash 
(vram2.sim), and the simulator log output (test.log). Each
of these files will have a test number appended.

The tests themselves are in the file "tests". Comments in
that file provide information regarding the test parameters.

The output of run_tests.pl will go to stdout, so to save
this information you may want to redirect stdout
accordingly.
