Log Message:
Initial commit of a 2 stage bootloader for NetBSD/mipsco.   Based on pmax
and alpha ports.

Uses PROM standalone I/O functions but due to the lack of a lseek function
it currently only works with version 5.40 of the firmware.  A more portable
solution is being worked on.

installboot utility requires several changes in order to correctly install
the bootstrap code - there is a "volume directory" which contains a list
of filenames, start sectors and length.  We need to add a "boot" entry of
the correct length starting at block 2.  The boot file has to be ecoff
which means we waste another 0.5k

Normally the Mips filesystem has a ~500k partition for this purpose but it
should be possible to squeeze it all into the first 7k "BSD Style" (1k is
required for 2 different copies of the partition table)

Only the bootxx_ffs first stage bootstrap has been tested via bootp() which
loads the second stage off disk and then boots the kernel.
