stpc-consumerII

[Steve M. Gehlbach]

Ron:

I have added the stpc consumer II chip and ST evaluation motherboard to the
linuxbios source and propose to add it to the repository.  The added code
supports a video console and sets up the integrated vga into alpha mode
(BIOS mode 3).  The graphics mode is not supported (yet anyway).

Remaining to be done is the pirq routing; I am not clear on how this is done
in linuxbios.  Maybe someone can point me in the right direction.  I know
how to do it for the stpc cpu/integrated bridge, but I don't understand how
this is connected to the data structures of linux bios.

Also remaining to be dealt with is the mtd device on the mobo. Right now it
boots 2.2.21 fine from a floppy ( I changed the floppy code to read a track
at a time; way too slow the way it was.)

The following files/directories are proposd to be added:

freebios/src/cpu/stpc/consumer2/Config
freebios/src/cpu/stpc/consumer2/stpc_cache.inc
freebios/src/cpu/stpc/consumer2/stpc_chip.inc

The following files were modified:

RCS file: /cvsroot/freebios/freebios/src/arch/i386/lib/params.c,v
RCS file: /cvsroot/freebios/freebios/src/lib/floppy_subr.c,v
RCS file: /cvsroot/freebios/freebios/src/lib/linuxbiosmain.c,v

RCS file: /cvsroot/freebios/freebios/src/pc80/Config,v
RCS file: /cvsroot/freebios/freebios/src/rom/floppy_fill_inbuf.c,v

A config option was added:  VGA_HARDWARE_FIXUP.

Let me know if you want to add this to the project, and the best way to get
the files to you.  Would it be better to wait until the mtd and pirq are
working?
