In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_dsp_rproc: Add custom memory copy implementation for i.MX DSP Cores The IRAM is part of the HiFi DSP. According to hardware specification only 32-bits write are allowed otherwise we get a Kernel panic. Therefore add a custom memory copy and memset functions to deal with the above restriction.
