-+        The IXP4xx is limited to a 64MB window for PCI DMA, which
-+        requires that PCI accesses >= 64MB are bounced via buffers
-+        below 64MB.
-+
-+        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
-+        kernel's generic bounce code.

-+        below 64MB.
-+
-+        Disabling this option allows you to omit the support code for
-+        DMA-able memory allocations and DMA bouncing, but the kernel
-+        will then not work properly if more than 64MB of RAM is present.
