[ARM] add Marvell Loki (88RC8480) SoC support
The Marvell Loki (88RC8480) is an ARM SoC based on a Feroceon CPU core running at between 400 MHz and 1.0 GHz, and features a 64 bit DDR controller, 512K of internal SRAM, two x4 PCI-Express ports, two Gigabit Ethernet ports, two 4x SAS/SATA controllers, two UARTs, two TWSI controllers, and IDMA/XOR engines. This patch adds support for the Marvell LB88RC8480 Development Board, enabling the use of the PCIe interfaces, the ethernet interfaces, the TWSI interfaces and the UARTs.
