    dm: Expand the uclass for Platform Controller Hubs (PCH) · ca831f49
    Simon Glass authored
    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.
