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	8e0389b973	ram: Rework main RAM interface This replaces the simple_ram_behavioural and mw_soc_memory modules with a common wishbone_bram_wrapper.vhdl that interfaces the pipelined WB with a lower-level RAM module, along with an FPGA and a sim variants of the latter.
