socrates: add USB support

From: Sergei Poselenov <[email protected]>

Add new configuration variable CONFIG_PCI_OHCI_DEVNO. In case of several PCI USB controllers on a board this variable specifys which controller to use.
See doc/README.generic_usb_ohci for details.

Markus, please note that we added a new configuration variable, CONFIG_PCI_OHCI_DEVNO in drivers/usb_ohci.c. It addresses the the case when there are several USB controllers installed on a board (like on socrates, where 4 PCI OHCI USB controllers are available), and we need to support a controller instance other than the first found.

For socrates, currently it is the 2nd OHCI controller of the 2nd ISP1562 PCI USB chip (i.e. instance number 3 in the PCI list of OHCI controllers (0x1131/0x1561)).

1.5.4.2

Sergei, Wolfgang,

Patch looks ok (and passed the sequoia test) so:

But for the future:

- The subject is less than meaningful.

- I would have really preferred two patches, one for the generic change and one for updating the board config.

Wolfgang, do you want to pick this one up directly (preferably with a more meaningful subject) or shall I push it through the usb tree. Either is fine for me.

Best regards

Markus Klotzb?cher

Dear Markus,

It would be nice if you could take this through the USB repo (and send a pull request soon :-) And please also fix the subject.

Thanks.

Best regards,
