Hi Moudy,

This firmware fails to load when using the dual core SCP DT description [1]:

  [   79.494105] remoteproc remoteproc0: powering up scp
  [   79.496217] remoteproc remoteproc0: Booting fw image mediatek/mt8188/scp.img, size 636548
  [   79.497298] platform 10500000.scp: IPI buf addr 0x000ffb40
  [   79.498013] platform 10500000.scp: IPI buffer does not fit in SRAM.

Please submit the firmware that works with the dual-core SCP description.

Thanks,
Nícolas
