c224072d61 MFi386: r241300 
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

4f88092408 Consolidate duplicate definitions of V86_CY() and V86_ZR() which check for 
the carry and zero flags being set, respectively, in <btxv86.h> and use
them throughout the x86 boot code.

91dfd26985 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().

5c5b5d4607 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.

932d8c46a2 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.

31062da1b0 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.
