Benjamin Herrenschmidt f9f18906a3 soc: Rename wb_dram_ctrl to wb_ext_io and rework decoding ... This makes the control bus currently going out of "soc" towards litedram more generic for external IO devices added by the top-level rather than inside the SoC proper. This is mostly renaming of signals and a small change on how the address decoder operates, using a separate "cascaded" decode for the external IOs. We make the region 0xc8nn_nnnn be the "external IO" region for now. This will make it easier / cleaner to add more external devices.
