My intention is to express that current SCP driver supports bring-up, 1. the single core SCP, e.g. MT8183 2. the 1st core of dual-core SCP, e.g. MT8195 Perhaps rewriting as follows is preferable? "The mediatek remoteproc driver currently only allows bringing up a single core SCP. It only supports bringing up the 1st core in SoCs with a dual-core SCP." > > > the 2nd core of a dual-core SCP. > > > > Best regards, > Krzysztof
