Paul Mackerras	ca4eb46aea	Make wishbone addresses be in units of doublewords or words This makes the 64-bit wishbone buses have the address expressed in units of doublewords (64 bits), and similarly for the 32-bit buses the address is in units of words (32 bits). This is to comply with the wishbone spec. Previously the addresses on the wishbone buses were in units of bytes regardless of the bus data width, which is not correct and caused problems with interfacing with externally-generated logic.

Benjamin Herrenschmidt	dbb137437c	acorn: Add support for the Acorn CLE 215+ This is a NiteFury based PCIe M2 form-factor board originally used for mining. It contains a speed grade 2 Artix 7 200T, 1GB of DDR3 and 32MB of flash. The serial port is routed to pin 2 (RX) and 3 (TX) of the P2 connector (pin 1 is GND). Note: Only 16MB of flash is currently usable until code is added to configure the flash controller to use 4-bytes address commands on that part.
