d343a5cdea Remove the string ">>> FreeBSD/i386 BOOT". I need to reduce the size of 
boot2 by 16 bytes.  I expect this to be temperary until the boot2 authors
can do the proper fix.

6f74dc01b4 Damn, I thought I had committed this already, but it seems not. 
Move the relocated boot1 and arg transfer space from 0x600/0x800 to
0x700/0x900.  In theory this should make no difference, apart from the fact
that Buslogic controllers happen to use a few bytes at 0x600 for some sort
of scratch space for it's int 0x13 hook (!!!), causing the machine to crash
badly when the boot2 code makes it's callbacks into boot1 for disk IO.

7ff854a690 Implement a simple LRU block cache. By default this is initialised to 16k, 
and will bypass transfers for more than 8k.  Blocks are invalidated after
2 seconds, so removable media should not confuse the cache.

The 8k threshold is a compromise; all UFS transfers performed by
libstand are 8k or less, so large file reads thrash the cache.
However many filesystem metadata operations are also performed using
8k blocks, so using a lower threshold gives poor performance.

Those of you with an eye for cache algorithms are welcome to tell me
how badly this one sucks; you can start with the 'bcachestats' command
which will print the contents of the cache and access statistics.

ea08aa4013 Fix comconsole mode. The int 0x14 read and status commands were reversed. 
Also, make sure we set %dx each time around otherwise the commands
suddenly start trying to work on things like com92 instead of com1.
Make sure comc_init() is only run once.
Cosmetic change to init-time character eater.

cf0b734c3d Attempt to at least align MODINFO_* blocks. IMHO, decoding this stuff

preload data.  MI code can't be expected to know how to deal with pmap
internals, assuming it gets done via pmap that is. :-)

biosdisk.c
	Save the slice table and disklabel when opening a disk.
	Add bd_getdev(), which attempts to return a dev_t corresponding
	to a given device.  Cases which it still doesn't get right:
	 - The inevitable da-when-wd-also-exists
	 - Disks with no slice table (the slice number is not set correctly)
	The first is difficult to get right, the second will be

a79bd7a693 First shot at loading elf symbols. Things are a bit strange because 
of the ..umm.. "wierd" way binutils lays out the file.  The section
headers are nearly at the end of the file and this is a problem when
loading from a .gz file which can't seek backwards (or has a limited
reverse seek, ~2K from memory).

This is intended to be compatable with the ddb/db_elf.c code and the
alpha/libalpha/elf_freebsd.c layout.  I've studied these (which are NetBSD
derived) but did it a bit differently.  Naturally the process is similar
since it's supposed to end up with the same result.

Based heavily on aout_freebsd.c.  Hmm.. There's so much in common that
these could probably be combined and just check the metadata to see which
format it is.
