-+	  The IXP4xx is limited to a 64MB window for PCI DMA, which

-+
-+	  The kernel has traditionally handled this issue by using ARM
-+	  specific DMA bounce support code for all accesses >= 64MB.
-+	  That code causes problems of its own, so it is desirable to
-+	  disable it.
-+
-+	  Enabling this option makes IXP4xx continue to use the problematic
-+	  ARM DMA bounce code. Disabling this option makes IXP4xx use the

-+
-+	  Disabling this option allows you to omit the support code for
