 * Xilinx ML510 Reference Design support
 *
 * This DTS file was created for the ml510_bsb1_pcores_ppc440 reference design.
 * The reference design contains a bug which prevent PCI DMA from working
 * properly.  A description of the bug is given in the plbv46_pci section. It
 * needs to be fixed by the user until Xilinx updates their reference design.
