Alex,
please probe this. If it will not help, pq2ads_setup_pci should be digged for
some board specifics.
Also, check if hose->set_cfg_type is 1 as done for ads8272.

Subject: [patch 01/34] ppc32: Fix incorrect PCI frequency value
Date: Thu, 01 Dec 2005 00:51:15 -0800
From: [EMAIL PROTECTED]
To: torvalds at osdl.org
CC: akpm at osdl.org, vbordug at ru.mvista.com, galak at kernel.crashing.org
From: Vitaly Bordug <[EMAIL PROTECTED]>
The time to wait after deasserting PCI_RST has been counted with incorrect
value - this patch fixes the issue.
