This code gets us to a working linux boot on the alix1c. I have not tested
Ethernet yet. The fixes are a board-specific fake spd_read_byte, cleaning up
comments, and just in general customizing for the 1c.
change fixes a bug (&& used instead of ||), adds some debug prints which were
VERY useful debugging the alix1c, changes fatal error messages from print_debug
to print_emerg, and adds two functions:
banner, which just prints out a string with a banner, and
hcf, which print an emergency message and then pushes null bytes
into the uart forever, just to make sure that no bytes get lost
for any reason.
