48ebb77e0e Add -fdata-sections, which is a new GCC 2.95 optimization. Remove 
-fschedule-insns as it wasn't such a big win with 2.95 after all.

Add the *BIG* win "-mpreferred-stack-boundary=2" optimiztion submitted by
Dima.  GCC 2.95 ensures the stack frame is always properly [opitimally]
aligned by surrounding every function call by code simular to
"addl $-12, %esp" / "addl $12, %esp".  Here we need the reduction in space,
with speed not an issue.

b3fde7d733 Return this file to its pre-spammed version. Thanks to some new compiler 
optimizations, we can go from 3 bytes free with the spammed version, to

b6bb24fced Enter complier upgrade mode again. We need to cut 169 bytes from this: 
Remove some printf() calls, reduce size of buffers, and abbreviate
	some strings.

Hopefully the boot people will fix this spamage after the cut over to
Gcc 2.95.2 as the system compiler.

aaa5ed29fd Turn on the -fforce-addr and -fschedule-insns optimizations. Adding 
either one gives us an additional 32 bytes of additional space available
when using EGCS 1.1.2.  With GCC 2.95.2 -fforce-addr gives us 12 more bytes,
and adding -fschedule-insns gives us an additional 4 bytes.

b203e98b2b aThis patch updates the BTX to emulate the BIOS function "Copy Extended 
Memory" called as function 0x87 of interrupt 0x15.  Since the Mylex RAID
adapter's BIOS used this function to access memory (actually PCI bus
space) beyond 16 MB, this patch also allows BTX to address all 4 Gig of
possible address space on i386+.  Since the loader does not have room for
4 MB of page tables, this was done by turning off paging.

Paging was turned off via a compile time setting which defaults to off.
To enable paging, simply define the make variable PAGING.

rnordier might want to clean this up later.

numbers that we have been doing in the past, and read /etc/fstab off the
proposed root filesystem to determine the actual device name and vfs

via the environment variable vfs.root.mountfrom.

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.

45c6ebc96d Simplify the "is a character ready" test, so that we don't return a false 
negative for keypresses with zero ascii values.  This is in line with the
comconsole test, rather than being more ambitious.

638a858945 Treat all options as toggles (ie. -c -c is the same no -c). Since 
the boot.config settings are persistent, this seems to provide a
useful override capability, and should break only on broken
boot.config's.

ebcd17d6c6 biosboot compatibility fix: 
Read boot.help before parsing boot.config.  We were parsing
boot.config first, which could result in boot.help being read
from a different location (or not found), which would probably
just cause surprise, without being useful.
