In general, this sounds like a U-Boot problem more than a coreboot problem (since you're clearly getting into U-Boot code execution), and you'd probably have better luck asking on the U-Boot mailing lists for help.

Dear Sir.

My env is see below.

board : Intel rangeley MOHON PEAK.(CPU is C2358)

I was success boot coreboot + SeaBIOS.

This time, I'm try to boot coreboot + u-boot(16.05).

But u-boot is every time fail. log is see below.

U-Boot 2016.05-rc3 (Nov 28 2016 - 17:04:31 +0900)

CPU: x86_64, vendor Intel, device 406d8h DRAM: 4 GiB

dm_pci_hose_probe_bus: Internal error, bus 'pch@1,0' got seq 0, expected 1

This says that U-Boot is scanning a bridge and expects to to be bus number 1, but it is bus number 0. I'm not quite sure how this can happen. Try 'dm tree' to list the devices. Or put a call to dm_dump_all() in dm_pci_hose_probe_bus().

Using default environment

Video: No video mode configured in coreboot!

This is because you need to enable the display in coreboot (if you want to).

Model: QEMU x86 (I440FX)

Here you are using the qemu board. You might want to create a new device tree file. If you see qemu-x86_i440fx.dts you may need to change the PCH address?

dm_pci_hose_probe_bus: Internal error, bus 'pch@1,0' got seq 0, expected 1 initcall sequence 7fc59100 failed at call 01110185 (err=-32) ### ERROR ### Please RESET the board ###

You can use:

grep 7fc59100 System.map

to find the function that is failing. But I'm pretty sure it is because of the PCI problem, since it returns -EPIPE.

Every time occured fail on the interrupt_init().

But I don't have a solution.

I was attached the config of corebooe and u-boot.

Please advise to me.

Can you explain why you are using coreboot first? Is it because you don't want to support this platform on U-Boot? It would be more work, at least unless you have an FSP.

I talked with one of the coreboot guys about setting up a U-Boot config that reads everything it needs from coreboot, instead of requiring its own configuration. Then we would not have these problems. However I haven't actually worked on this as I don't actually have a board that fails...maybe soon.

Thank you.
