-+ 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.

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

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