Previously we raised patch to add secure-pil to existing rproc driver. 
Bjorn suggested to introduce a new secure-pil driver.

https://patchwork.kernel.org/project/linux-arm-msm/patch/1611984013-10201-3-git-send-email-gokulsri@codeaurora.org/ 


Also IPQ5018, IPQ9574 soc's follows multipd model. So we decided to
have new driver which consists 'secure-pil + multi pd' in one
place.

Thanks & Regards,
Manikanta.
