+ * Xilinx ML510 Reference Design support
+ * This DTS file was created for the ml510_bsb1_pcores_ppc440 reference
design.
+ * The reference design contains two bugs which prevent PCI from
working which
+ * should be fixed by the user:
+ * - the MPLB output of the soft-core should be connected to
plbv46_plb_1 which
+ *   corresponds to SPLB0 of the ppc440 to allow the soft-core to
access system
+ *   memory
+ * - C_IPIFBAR2PCIBAR_0 of the soft-core should be set to 0x80000000 in
order to
+ *   reserve 0x80000000-0xffffffff (PCI) for memory mapped i/o and the
lower addresses
+ *   can be used by PCI devices to access system memory (DMA).
+ *

the PLB bus which is seen by the CPU at 0xa0000000.

+			 * of bits that are the SAME between C_IPIFBAR_N and
C_IPIF_HIGHADDR_N.'

means:

+			 * C_IPIF_HIGHADDR_0  = 0xbfffffff <- only the last 3 bits of

similar

+			 * This means that a CPU write to 0xa0001234 translates to
0x00001234 on the PCI bus and that
+			 * the pcibar_0 base and pcibar_1 base are zero. In order to prevent
collision between inbound
