Hi all,
I'm trying to add a new superIO chip to the source tree. The chip is an EXAR XR28V932. I tried to take example of the existing superIO chips, like the i3100 and it8716 to compose a correct source tree as following: [agrain1@frilldlin059 coreboot]$ ls -als ./src/superio/exar/xr28v382/ total 10 1 drwxr-xr-x 2 agrain1 dhs2 512 Dec 16 09:03 . 1 drwxr-xr-x 3 agrain1 dhs2 512 Dec 15 09:41 .. 1 -rw-r--r-- 1 agrain1 dhs2 687 Dec 15 09:34 Makefile.inc 3 -rw-r--r-- 1 agrain1 dhs2 2614 Dec 16 09:03 superio.c 2 -rw-r--r-- 1 agrain1 dhs2 1287 Dec 15 16:28 xr28v382.h
I modified the devicetree.cb of my board (based on an Intel Mohon Peak) as following: device pci 1f.0 on end # LPC bridge chip superio/exar/xr28v382 # Super I/O device pnp 2e.0 on # Com1 io 0x60 = 0x3f8 irq 0x70 = 4 end device pnp 2e.1 off # Com2 end device pnp 2e.8 off # Watchdog end end device pci 1f.3 on end # SMBus 0
Now the output of the console log (DEBUG level): <...> PCI: pci_scan_bus for bus 00 PCI: 00:00.0 [8086/1f0f] enabled PCI: Static device PCI: 00:01.0 not found, disabling it. child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device child PNP: 002e.0 not a PCI device <...> PCI: 00:1f.0 [8086/1f38] enabled child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device child PNP: 002e.0 not a PCI device child PNP: 002e.1 not a PCI device child PNP: 002e.8 not a PCI device PCI: 00:1f.3 [8086/1f3c] enabled child PNP: 002e.0 not a PCI device <...> PCI: Left over static devices: PNP: 002e.0 PNP: 002e.1 PNP: 002e.8 PCI: Check your devicetree.cb.

I guess that the "" are not normal, isn't it ? And so the " Check your devicetree.cb." ? Moreover, I put a printk() in the init function of the chip and do not see it in the log. What particular point should I also check to be sure that I do not miss anything ?
Thanks for your help. Best regards, Patrick Agrain
