[PATCH] powerpc/85xx:Create dts of each core in CAMP mode for P1020RDB
Prabhakar Kushwaha

Thu Apr 28 17:00:00 EST 2011
Create the dts files for each core and splits the devices between the two cores
for P1020RDB.
Core0 has core0 to have memory, l2, i2c, spi, gpio, tdm, dma, usb, eth1, eth2,
sdhc, crypto, global-util, message, pci0, pci1, msi.
Core1 has l2, eth0, crypto.
MPIC is shared between two cores but each core will protect its interrupts from
other core by using "protected-sources" of mpic.
Fix compatible property for global-util node of P1020si.dtsi.
