Subject[RESEND PATCH] firmware: imx: Allow IMX DSP to be selected as module
From: Daniel Baluta <>

IMX DSP is only needed by SOF or any other module that
wants to communicate with the DSP. When SOF is build
as a module IMX DSP is forced to be built inside the
kernel image. This is not optimal, so allow IMX DSP
to be built as a module.
