Hi,
this patch adds main support for BCOM's Winnet100 Geode GX1 based terminal. It activates the VGA support so it would be possible to run this target as a small (and silent) X terminal. With faster SDRAM timing (not yet supported in mainline) it can run graphical resolutions up to SXGA (1280x1024) at 64k colours.
I'm not sure if all files I add to src/mainboard/bcom/winnet100 are required. Most of them are copies from other GX1 based mainboards.
Tested on my IGEL316 terminal (=BCOM Winnet100) with 64MiB SDRAM, kernel 2.6.22 and Xorg 7.1.

I'm not sure if all files I add to src/mainboard/bcom/winnet100 are required. Most of them are copies from other GX1 based mainboards.
Nope, not all are required. And most miss a GPL header which we should add.

Missing GPL header. This is just (relatively small) config file (which should have a common part somewhere global btw, but that's for another patch) so I'm not sure if we have to track down all of this to the first author of this code (which is used in basically _every_ board).
I'd just slap a '(C) Juergen Beisert' on it and that's it. Counter-opinions welcome, but only with a patch to add the original author to all Config.lb files then ;-)

Please use the global src/arch/i386/lib/failover.c instead of a local duplicate of the file (i.e. drop failover.c).

What's the exact spelling in the manual or on the PCB? We should try to use the "correct" name, if possible.

Hm, I'd do it the other way around (but it doesn't matter much):

- option ROM_IMAGE_SIZE=0x10000

Same here.
Patch looks good, with the above fixes I think we can commit it.
Uwe.
Uwe,
its really hard to make you happy...

this patch adds main support for BCOM's Winnet100 Geode GX1 based terminal. It activates the VGA support so it would be possible to run this target as a small (and silent) X terminal. With faster SDRAM timing (not yet supported in mainline) it can run graphical resolutions up to SXGA (1280x1024) at 64k colours.
I'm not sure if all files I add to src/mainboard/bcom/winnet100 are required. Most of them are copies from other GX1 based mainboards.
Nope, not all are required. And most miss a GPL header which we should add.
But without them I now must know what I'm doing...

If you're not using the CMOS option table, you can drop the cmos.layout file.
Without the cmos.layout file I now get:

Ah, I meant to just add them to targets/.../Config.lb (in addition to Options.lb). I don't think we do this everywhere, but I have the feeling that targets/.../Config.lb is meant for user changes (and Options.lb rather not in the normal case). I might be wrong, though.

Ah, yes, sorry. You have to drop the dependency on option_table.h in src/.../Config.lb like this:
makerule ./auto.E # depends "$(MAINBOARD)/auto.c option_table.h ./romcc" depends "$(MAINBOARD)/auto.c ./romcc" action "./romcc -E -O -I$(TOP)/src -I. $(CPPFLAGS) $(MAINBOARD)/auto.c -o $@" end makerule ./auto.inc # depends "$(MAINBOARD)/auto.c option_table.h ./romcc" depends "$(MAINBOARD)/auto.c ./romcc" action "./romcc -O -I$(TOP)/src -I. $(CPPFLAGS) $(MAINBOARD)/auto.c -o $@" end
I've already done that before the commit, the code builds fine for me now.
Uwe.

Options.lb lists all options that are used by the target and their defaults.
Config.lb can only override defaults as set in Options.lb.

Hi,
here comes the second try.
Subject: Adding BCOM Winnet100, 2nd try
From: Juergen Beisert juergen@kreuzholzen.de
This patch adds BCOM's winnet100 to the supported mainboards. Refer http://www.linuxbios.org/index.php/BCOM_WINNET100_Build_Tutorial for hardware description.
Corrections mentioned by Uwe added. But now it fails due to missed cmos.layout file. Perhaps someone can fix it, who knows why.
Patch is against LinuxBIOSv2, revision of 2007-10-09

Corrections mentioned by Uwe added. But now it fails due to missed cmos.layout file. Perhaps someone can fix it, who knows why.
Patch is against LinuxBIOSv2, revision of 2007-10-09
Signed-off-by: Juergen Beisert juergen@kreuzholzen.de
Thanks, committed with some small changes in r2843.
Changes:
- Drop lots of useless/duplicated generic comments from Option.lb/Config.lb, which we already have in 95% of the boards. We don't need another copy. Instead we should move those comments in the wiki or some README...
- Add this to Options.lb for flashrom checking: default MAINBOARD_VENDOR = "BCOM" default MAINBOARD_PART_NUMBER = "WinNET100"
- Fix build error wrt cmos.layout and failover.c
- Mention VGA options and loglevel in targets/.../Config.lb for convenince.
- Random small cosmetic changes.
Will give this a try on hardware soon and report back. I think some things in Config.lb might need small fixes. Do you get any output from 'lspnp -v' on this board?
Uwe.

My kernel states:
[...] isapnp: Scanning for PnP cards... isapnp: No Plug & Play device found [...]
And lspnp is very "silent":
$ lspnp -v $
No output from lspnp. :-(
BTW: The BCOM winnet100 from the repository runs on my hardware.

Why: "Tested with irqpoll kernel parameter. Tested: USB thumb drive."? My patch contains a valid IRQ routine table! All right, to use it, the kernel needs a patch...

Yep, done now. There was some Slashdot-related downtime, so I couldn't do it earlier.

Why: "Tested with irqpoll kernel parameter. Tested: USB thumb drive."? My patch contains a valid IRQ routine table! All right, to use it, the kernel needs a patch...
Yes, I was just too lazy to recompile kernels yesterday, so I used irqpoll for now (which is slower, but works too). Will test your patches later.
I have not yet read all of your PDF and all code, but there seem to be lots of useful patches in there... I hope we can merge all/most of them soon (in LinuxBIOS as well as in Linux). Please send patches for the stuff which is ready to be committed...
Currently I'm using FILO + a 2.5" hard drive on my IGEL-316 which works fine with the attached patch. With "irqpoll" both USB and ethernet also work fine with a stock 2.6.22 kernel.
Audio and VGA doesn't work, I guess I'll need your patches/drivers. The "nsc" Xorg driver requires VSA, correct? The LinuxBIOS VGA part works fine, the logo is displayed!
Some questions about the status table at http://linuxbios.org/BCOM_WINNET100_Build_Tutorial:
- For "COM2" you wrote: "Simple UART mode only (due to TTL level)". What exactly does that mean? There's no COM2 connector an the back, and I don't see any headers to attch one on the board, either. Is COM2 usable somehow?
- I didn't test the parallel port with anything useful yet, but simply doing 'modprobe ppdev' works without errors, the module loads fine.
- Any ideas about the smartcard reader? Not that I need it, but it would be useful to know the status. Do we know something about how it works (datasheets?) or is there even some Linux driver for it? Does it need special init in LinuxBIOS?
Oh, and btw, someone seems to have had a lot of fun (this is from the original BIOS image):

Ready to be committed *where*?

Audio is currently broken. The SMI polling driver needs to be modified (fails to compile).
The "nsc" Xorg driver requires VSA, correct?
Yes. I does video mode setting in the standard way, what means it touches VGA registers that do not exist on Geode GX1. Also it relies on a working scratch RAM configuration. What is not done within LB.
The LinuxBIOS VGA part works fine, the logo is displayed!
Same here.
Some questions about the status table at http://linuxbios.org/BCOM_WINNET100_Build_Tutorial:

Take a look at the board, near the Super IO you will find a 12 pin header (or 10 pin header, with a card reader connected on my IGEL316). On my board it is marked as "JCOM1". This is the second UART, but without a level shifter! All levels are TTL only!
JCOM1 /---\ DCD2 1 7 DSR2 SIN2 2 8 RTS2 SOUT2 3 9 CTS2 DTR2 4 10 RI2 GND 5 11 VCC (5V) GND 6 12 nc (not assembled) ---/
These signals could also be (depends on the SuperIO configuration):
DTR2 could be also CFG1 and BOUT2 SOUT2 could be also GPIO36 SIN2 could be also GPIO35 DCD2 could be also GPIO31 DSR2 could be also GPIO32 RTS2 could be also GPIO34 CTS2 could be also GPIO30 RI2 could be also GPIO33
- I didn't test the parallel port with anything useful yet, but simply doing 'modprobe ppdev' works without errors, the module loads fine.
I never used the lpt on this device.
- Any ideas about the smartcard reader? Not that I need it, but it would be useful to know the status. Do we know something about how it works (datasheets?) or is there even some Linux driver for it? Does it need special init in LinuxBIOS?
I did not find any documentation about the used device. I only know its connected through the UART2 with TTL levels.

The 'B' could also be a bad printed '8'

It seems to work only with VCC/RxD/TxD/GND as there are only 4 wires.

Great. Hmm, but it seems our one is connected to the Super-IO UART. But the kernel states:
[...] <6>cardman_usb.c v2.3 2003/03/26 support.linux@omnikey.com <6>usb.c: registered new driver cardman [...]
So it seems more an USB based device. I'm confused.
No docs.

That's just the driver being loaded and registered. There's no sign of a USB device driven by the driver.
To double check you can of course do lsusb or cat /proc/bus/usb/devices
No docs.
:-(
If it is indeed USB and implements the CCID device class there's no need for docs. :)

But activating COM2 at least will be required, I guess? It's active in the original BIOS (appears in /proc/ioports).

Juergen, can you post 'lsmod' and 'ps auxw' in the original version of the BIOS/DoC software? Maybe also a dmesg (full boot log). My guess is that the card readers worked with their software, and as that's Linux-based maybe we just have to find the correct driver name?
I can't seem to find a button where I can put the box into upgrade mode in order to get a shell. The settings screen is password protected on my box, that may be the reason. I'll see if I can work around that.

Smart card readers rarely have kernel drivers, but maybe there's an ifdhandler running.

The Super-IO supports two generic UARTs. If there are level shifters connected or not, doesn't matter. UART is UART. Setup fails?

No chance. There is no original environment present anymore. All five Igel's running here as X clients.
Attached some files I found in my filesystem. I looks like they are from the original system (but: I'm NOT sure!)

Dunno, it's set to off in Config.lb at the moment, I didn't try to activate it, but I'll do that later... I think we should change the svn code to enable it anyway. The hardware is there and (theoretically) usable so we should enable it.

As I remember right, my five IGELs contained three types of software configurations. So I'm not sure if we can compare our systems (I think the hardware only is the same).
