5272ce4796 - RBX_MASK wasn't updated when RB_PAUSE was changed from 0x40000
to 0x100000 in rev. 1.67.

- NOPT wasn't updated (decremented) in previous revision.

a00a259113 Add the ability to specify the boot2 serial console speed in
/boot.config or on the "boot:" prompt line via a "-S<speed>" flag,
e.g. "-h -S19200". This adds about 50 bytes to the size of boot2
and required a few other small changes to limit the size impact.
This changes only affects boot2; there are further loader changes
to follow.

0ed36875f4 Ensure GCC does not use FP registers in integer code.
I think all we really need is -fno-sse2.
I really don't like cluttering up the compiler invocation,
but this bigger hammer will fix reported problems for now.

ca9b2364c3 A long, long time ago in a CVS branch far away (specifically, HEAD prior
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg.  Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2.  This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).

a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)
to build the kernel. It doesn't affect the operation if gcc.

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:
 - in_cksum.[ch]:
   * use a generic C version instead of the assembly version in the !gcc
     case (ASM code breaks with the optimizations icc does)
     -> no bad checksums with an icc compiled kernel
     Help from:		andre, grehan, das
     Stolen from: 	alpha version via ppc version
     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

     This change changes the contents of the object file, but as it's

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

bcd106e18b - Factor out -nostdlib to an upper level Makefile.inc.
- Now that bsd.prog.mk deals with programs linked with -nostdlib
  better, and has a notion of an "internal" program, use PROG
  where possible.  This has a good impact on the contents of
  .depend files and causes programs to be linked with cc(1).

4d450ff944 Changed the RB_PAUSE flag from 0x40000 to 0x100000 and marked the old
value as reserved for internal use in boot blocks, because RB_PAUSE
broke binary compatibility by usurping the RB_DUAL flag.  Probably no
one except me has boot blocks for which this matters, since most boot
blocks based on biosboot including pc98's boot2 can't boot elf kernels,
and /boot/loader doesn't properly pass flags set by the previous stage.

reboot.h:
Also mark the historical RB_PROBEKBD flag (0x80000) as reserved for
internal use in boot blocks.

boot2.c:
Added comments to inhibit usurping of other flags.

129540b834 Include <sys/reboot.h> the definition of RB_BOOTINFO. The previous
commit broke the world because it depended on namespace pollution that
was only in my version of <machine/bootinfo.h>.  The include was removed
in rev.1.63 after the last reference to it went away in rev.1.61.

c00209396c Fixed loss of setting of the RB_BOOTINFO flag in rev.1.43. Fixed wrong
comment about this flag in rev.1.61.  It is not historical like the
comment said; it is the flag that says that most of what is laboriously
put in the bootinfo struct is actually there.  Newer kernels were
bootable by even the broken boot2 without losing anything except the
symbol table, but older kernels need at least the memory sizes.

Restoring the "|" with RB_BOOTINFO that was lost in rev.1.43 costs 5
bytes.  The fix can be done in only 4 bytes by fixing some code that
was removed in rev.1.61 (put RB_BOOTINFO back in in the initial value
of "opts" and fix RBX_MASK to not clobber it.)

8e6206d943 Fix interactive booting:
o Revision 1.38 introduced the -n flag.  It conflicted with the
  RB_BOOTINFO flag, so was in effect always on.  Change the -n flag to
  be bit 0x1c instead of 0x1f.  This also had the consequence that a mal-formed
  /boot.config would render the system unbootable because the user was
  unable to enter anything at all on the command line.
o Remove the initialization of opt to be RB_BOOTINFO since we filter that bit
  out and do not otherwise use it.

2db4f48c6a Make both UFS1 and UFS2 fit on the same boot blocks. These are a
subset of Peter's patchs that are believed to be safe.

Makefile tweaks:
o -fomit-frame-pointer
o Change default to building both UFS1 and UFS2 bootblocks.

Lots of boot2 tweaks:
o lookup is only ever called with kname, so use it directly.
o inline memsize
o getstr are only ever called with cmd, so hardware that.
o tweaks to the parsing code to test after the conversion rather than
  before since we tested after anyways.
o eliminate support for %x in printf.
o eliminate a few bytes in printfs.
o Tweak the boot banner.
o eliminate support for wd and "  " devices (I might add wd back to
  keep bde happy).
o eliminate support for a few arguments.

This takes us from -162 bytes free to 67 bytes free.

I've tested this only on a few systems, so be careful when updating to
this change.
