i386-linuxbios loader.

[Johan Rydberg]

I've pushed the following two changes into both the official
repositories.  This should be enough for you to compile your own
version of LinuxBIOS+GNUFI and test it on QEMU.

  2006-12-20  Johan Rydberg  <address@hidden>

          * loader/i386/linuxbios/start.S: New file.
          * loader/linuxbios/loader.c: Likewise.
          * loader/linuxbios/debug.c: Likewise.
          * loader/linuxbios/linuxbios.h: Likewise.

          * configure.ac: Add i386-linuxbios loader.
          * configure: Regenerate.

          * config/i386-linuxbios.rmk: New file.
          * config/i386-linuxbios.mk: Likewise.

          * Makefile.in (RMKFILES): Add i386-linuxbios.rmk.

  2006-12-20  Johan Rydberg  <address@hidden>

          * ext/con-serial.c (struct simple_text_input): Declare.
          (QUEUE_SIZE): Define.
          (reset_output): New function name (old 'reset').
          (reset_input): New function.
          (input_loop): Likewise.
          (read_key_stroke): Likewise.
          (check_key_stroke): Likewise.
          (start): Register simple text input protocol.

There is still a lot of work left before I feel that someone should
try this with in a real LinuxBIOS environment (if ever), but it is a
start.  Contributions more than welcome, as always.

If you want some information on how to go about to try it out, I added
a page to the wiki:
