AM654/J721e has HyperBus Memory Controller that supports HyperFlash and HyperRAM devices. It provides a memory mapped interface to interact with these devices. Add a driver to support the same. Driver calibrates the controller, setups up for MMIO access and probes HyperFlash child node. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>
