From 585cf17561d3174a745bec49c422c1a621c95fc4 Mon Sep 17 00:00:00 2001 From: Tzachi Perelstein Date: Tue, 23 Oct 2007 15:14:41 -0400 Subject: [ARM] basic support for the Marvell Orion SoC family The Marvell Orion is a family of ARM SoCs with a DDR/DDR2 memory controller, 10/100/1000 ethernet MAC, and USB 2.0 interfaces, and, depending on the specific model, PCI-E interface, PCI-X interface, SATA controllers, crypto unit, SPI interface, SDIO interface, device bus, NAND controller, DMA engine and/or XOR engine. This contains the basic structure and architecture register definitions.
