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. Signed-off-by: Ilya Yanok <yanok@emcraft.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
