Hi,
here's a first patch for the 440BX code and the Tyan S1846 and the 82371EB southbridge which gets my Tyan S1846 a lot further in the boot process.
However, it cannot boot a payload, yet.
It seems the major problem was that I did ram_check() on the whole range from 0 - 64 MB (in my case; I use a 64 MB DIMM for testing). This cannot work of course, as the range from 640 KB - 1 MB is _not_ RAM but rather reserved for all kinds of other stuff (thanks Stefan for pointing this out!).
Leaving out that range, but checking the rest of RAM, I get a "DRAM range verified", so it seems RAM init _does_ work after all. (it's hardcoded to my board and setup of course, but that'll be fixed)
I've tried setting up the PCI devices correctly in Config.lb, but I'm absolutely not sure that I got it all right. Can somebody please check this and let me know of any stupid errors I made?
Here's the lspci output from the Tyan S1846:

And this is my current try to setup Config.lb:

Does that look correct?
Also, a full boot log is attached. The PCI init _seems_ to work, at least partially.
The current end of the story is that elfboot cannot find the payload, not sure why. Wrong PCI init? Wrong RAM init? Wrong payload location?
Thanks, Uwe.

Yup. I didn't even need to patch the latest svn version with the memory fix for DRAM to find my memory.
If I look at my log, I see:
PCI_DOMAIN: 0000 enabled PCI_DOMAIN: 0000 scanning... PCI: pci_scan_bus for bus 00 PCI: 00:00.0 [8086/7190] ops PCI: 00:00.0 [8086/7190] enabled PCI: 00:01.0 [8086/7191] disabled PCI: devfn 0x9, bad id 0xffffffff PCI: devfn 0xa, bad id 0xffffffff PCI: devfn 0xb, bad id 0xffffffff PCI: devfn 0xc, bad id 0xffffffff PCI: devfn 0xd, bad id 0xffffffff PCI: devfn 0xe, bad id 0xffffffff PCI: devfn 0xf, bad id 0xffffffff PCI: devfn 0x10, bad id 0xffffffff PCI: devfn 0x18, bad id 0xffffffff PCI: devfn 0x20, bad id 0xffffffff PCI: devfn 0x28, bad id 0xffffffff PCI: devfn 0x30, bad id 0xffffffff
The "0xffffffff" reminds me of seeing something when using hexedit with viewing the bios mtd flash device (ie. modprobe l440gx and hexedit /dev/mtd0) and not unmasking the bios flash device (or... using flashrom to enable the device).
Almost as if, we're mapping pci to memory, and the mapping isn't being written to ram? .. as such, can't load elf into memory ... and of course, can't execute from ram?
(Of course, I'm probably entirely wrong here.)
Attached my session.log, but I think it's very similar to yours except for my additional PCI devices along with 1GB of ram (all 4 banks filled).
I'm going to try only loading one bank of ram just for kicks.
Leaving out that range, but checking the rest of RAM, I get a "DRAM range verified", so it seems RAM init _does_ work after all. (it's hardcoded to my board and setup of course, but that'll be fixed)

fyi, similar layout here too.

Just to verify, irq 1 & 12 is keyboard for me.
/proc/ioports >> "0060-006f : keyboard" here.

Spent the whole day playing with options.
While getting more familiar with linux bios, I enabled PCI AGP & APIC and the code seems to have executed just fine & dandy here. I also tried enabling SMP, but seems it also needs MP code. But getting side tracked. :-/
I also saw a minor problem with the ordering of addition/subtraction in src/mainboard/tyan/s1846/Config.lb, the tyan/s2895 had specified a different order... wasn't it, i think.
Also tried using lzma on file.elf.
Would love to see more debug output from elfboot. :-/
The patch looks good to me as is.

Just curious, ill "v2_tyan_s1846_progress.patch" make it into the tree?
It looked good to me.

I sure hope so :) I'm waiting for an ACK and will then commit.

Can you dump the flash memory where the image should reside? Are you using a compressed image?
Did you enable full visibility of the flash chip? (PAM something)

Uwe probably has already done this, but I've yet to fiddle with this.

Interesting.

Ah, this might very well be the problem, thanks! I'll check this evening...
