EspressoBin PCI express driver

[Søren Schmidt]

Hi gang

I’ve been looking at that empty PCI-express slot on my EspressonBin’s for some time, and decided that it could be handy to either add a a SATA controller for NAS purposes or a Wifi card for routers.

I’ve hacked together a simple driver that allows that, grantet its crude but it works :)

pcib0: <Marvell Armada 37x0 PCI-express controller> mem 0xd0070000-0xd008ffff irq 5 on simplebus0
pci0: <PCI bus> on pcib0
ath0: <Atheros 9287> at device 1.0 on pci0
ath0: AR9287 mac 384.2 RF5133 phy 15.15
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x00c0

pcib0: <Marvell Armada 37x0 PCI-express controller> mem 0xd0070000-0xd008ffff irq 5 on simplebus0
pci0: <PCI bus> on pcib0
atactlr1: <Marvell AHCI controller> irq 46 at device 1.0 on pci0
atactlr1: AHCI v1.00 64bit controller, 4 6.0Gb/s ports, PM supported, NCQ supported w/FBS
ata2: <SATA 6.0Gb/s port at channel 0> on atactlr1
ata3: <SATA 6.0Gb/s port at channel 1> on atactlr1
ata4: <SATA 6.0Gb/s port at channel 2> on atactlr1
ata5: <SATA 6.0Gb/s port at channel 3> on atactlr1

It has only been used on my own hacked up version of 12-stable but should work on -current as well, YMMV..



Enjoy!

PS: I do have a cpufreq driver for it as well if anyone’s interested, but there is not much point in it since power savings are next to nothing….
