OMAPL138B-EP: Is there an alternative SoC to OMAPL138?

Tool/software:

Hello, 

We are using OMAPL138 SoC and we noticed the Linux SDK is no more supported in terms of latest version in Yocto Project. We would like to know if there is latest SoC with DSP C674x Floating-point DSP and ARM Processor for new design to allow us to get latest Linux and still use our current DSP application used on OMAPL138.

We are happy with the DSP algorithm we are using with SYSBIOS TI-RTOS. ONLY issue we have at this stage is the PHP and related Linux Tools are very old and our UI is slow. 

We are also using AM6254 chip on different project and that works well and since it is currently maintained we are using all latest tools in Linux. 

Is there any alternative SoC like OMAPL138 that is current supported in terms of Linux and also has DSP core for us to run RTOS? 

If not, what is your recommendation for us if we need to have better/latest supported Linux on SoC with DSP and ARM? 

Thanks
