From ca831f4933dc68d9ed1b6399cbda90068c520005 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 18 Jan 2016 20:19:17 -0700 Subject: dm: Expand the uclass for Platform Controller Hubs (PCH) A Platform Controller Hub is an Intel concept - it is like the peripherals on an SoC and is often in a separate chip from the CPU. The chip is typically found on the first PCI bus and integrates multiple devices. We have a very simple uclass to support PCHs. Add a few operations, such as setting up the devices on the PCH and finding the SPI controller base address. Also move it into drivers/pch/ since we will be adding a few PCH drivers.
