Need help on supporting Fabiatech FB2510 mainboard.

[Joey Nelson]

I have linuxbios partly working on this GX1/CS5530 based mainboard.

I created a mainboard/fabiatech/fb2510 directory and copied the files
from mainboard/advantech/pcm-5823.

In Config, I changed all references to FDC37B72x to FDC37B78x (By the
way superio/SMC/FDC37B78x/superio.c reports itself as FDC37B72x).
Everything else I left the same.  I based the build config off
config.example, changing the payload from eepro100.ebi to rtl8139.elf
(there was no make target for bin/rtl8139.ebi in Etherboot 5.1.7).

I tried to run getpir on the FB2510 under the existing Award Bios, but
it failed to find a valid PCI IRQ Routing table.  I include the output
below.

I went ahead and built linuxbios (using the irq_tables.c from pcm-5823)
and programmed the FB2510's flash with the resulting romimage.  Booting
with this romimage was quite successful up until configuring the com
port.  Booting freezes right after this point.

------ begin of linuxbios serial console output -------
  Call init
Enabling com device: 04
  iobase = 0x03f8  irq=4
------ end of linuxbios serial console output -------

Actually originally it would only print "io" from the last line.
Looking in superio.c I found that the comments said initialization
should be happening before enabling, but in the code it was happening
the other way around.  Looking in FDC7B72x it was done in the init then
enable order with a delay(1) between the init and enable.  So I went
ahead and made that change in FDC7B72x/superio.c.  After that I got the
above output.

I'm guessing this problem is because my irq routing table is not being
properly configured.  Is this a good guess?  How else can I get the
information to put in irq_table.c?
