9cc9d2e8b5 MFC r260949: 
Make comconsole options set before its activation to be remembered.

9f2f2e171a Change <sys/diskpc98.h> to not redefine the same symbols that are 
being defined in <sys/diskmbr.h>. Instead give the symbols here a
"PC98_" prefix. This way, both <sys/diskmbr.h> and <sys/diskpc98.h>
can be included in the same C source file.

The renaming is trivial. The only gotcha is that DOSBBSECTOR is
also redefined from 0 to 1. This because DOSBBSECTOR was always
used in conjunction with an addition of 1. The PC98_BBSECTOR symbol
is defined as 1 and the expression is simplified.

Note: it is not believed that ports are seriously impacted; or at
all for that matter.

i386 comconsole: don't loop forever if hardware doesn't respond

    - clear capability flags when hw timeouts
    - retire comc_started status variable and directly use c_flags to see
      if comconsole is selected for use

d957274e54 MFi386: part of revision 1.51 
Rework the read/write support in the bios disk driver some to cut down
  on duplicated code.
  - All of the bounce buffer and retry logic duplicated in bd_read() and
    bd_write() are merged into a single bd_io() routine that takes an
    extra direction argument.  bd_read() and bd_write() are now simple
    wrappers around bd_io().

67997e41d5 Slightly cleanup the 'bootdev' concept on x86 by changing the various 
macros to treat the 'slice' field as a real part of the bootdev instead
of as hack that spans two other fields (adaptor (sic) and controller)
that are not used in any modern FreeBSD boot code.

dc91b1990a Extend struct devdesc with a unit field, called d_unit. Promote the 
device (kind) specific unit field to the common field. This change
allows a future version of libefi to work without requiring anything
more than what is defined in struct devdesc and as such makes it
possible to compile said version of libefi for different platforms
without requiring that those platforms have identical derivatives
of struct devdesc.

f701a00d00 Drop the gateA20() function in the loader as it is unused. All the other 
boot loaders that load the loader already handle A20.  In fact, they are
required to do so in order to setup the environment that btxldr expects.
