From e4ff1c39ee1122198e8355069da59297038e55bb Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Sun, 22 Aug 2010 22:49:46 +0200 Subject: ARM: kirkwood: Unbreak PCIe I/O port The support for the 2 pcie port of the 6282 has broken i/o port by switching *_IO_PHYS_BASE and *_IO_BUS_BASE. In fact, the patches reintroduced the same bug solved by commit 35f029e2514be209eb0e88c7d927f3bcc42a5cc2. So, I'm adding back *_IO_BUS_BASE in resource declaration and fix definition of KIRKWOOD_PCIE1_IO_BUS_BASE. With this change, the xgi card on my t5325 is working again.
