powerpc/mpc8308rdb: support for MPC8308RDB board from Freescale
This patch adds support for MPC8308RDB development board from
Freescale.
Supported devices:
DUART
Dual Ethernet
NOR and NAND flashes
I2C
USB in peripheral mode
PCIE support is broken by the commit 3da34aa ("powerpc/fsl: Support
unique MSI addresses per PCIe Root Complex"). Works after revert.
