common: add PHYPadsReducer to only use specific DRAM modules.
...
For example on KC705, to only use the 4 first modules (bytes):
from litedram.common import PHYPadsReducer
ddram_pads = platform.request("ddram")
ddram_pads = PHYPadsReducer(ddram_pads, modules=[0, 1, 2, 3])
self.submodules.ddrphy = s7ddrphy.K7DDRPHY(ddram_pads,
[...]
On Arty, to only use the second module (byte):
from litedram.common import PHYPadsReducer
ddram_pads = platform.request("ddram")
ddram_pads = PHYPadsReducer(ddram_pads, modules=[1])
self.submodules.ddrphy = s7ddrphy.A7DDRPHY(ddram_pads,
