+Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If SoC has a CardBus we can set resources of device at slot 1 only. It's
+impossigle to set bridge resources as it simply overwrites device 1
+configuration and usually results in Data bus error-s.
