    5  * In CAMP mode, each core needs to have its own dts. Only mpic and L2 cache
    6  * can be shared, all the other devices must be assigned to one core only.
    7  * This dts file allows core0 to have memory, l2, i2c, spi, gpio, tdm, dma, usb,
    8  * eth1, eth2, sdhc, crypto, global-util, message, pci0, pci1, msi.
    9  *
   10  * Please note to add "-b 0" for core0's dts compiling.
