Changeset 10219:2d3875da859b --------------------------- mem: Add precharge all (PREA) to the DRAM controller This patch adds the basic ingredients for a precharge all operation, to be used in conjunction with DRAM power modelling. Currently we do not try and apply any cleverness when precharging all banks, thus even if only a single bank is open we use PREA as opposed to PRE. At the moment we only have a single tRP (tRPpb), and do not model the slightly longer all-bank precharge constraint (tRPab).
