Philip, do you think it is possible to also compile these modules for 
the current kernel: ti-lpm-module, ti-lpm-utils, ti-cmem-module?

With these modules we should be able to load different bios images on 
the DSP. Unfortunately after we load the first one, we cannot load a new 
the operation always fails. I read that using these modules we can set 
the DSP to low power mode and load a different bios image.
