Further update:

We have successfully cross compiled the kernel (linux-next) with this patch series
for AM335x and AM437x SOC respectively.

Kernel is booting well on both the SOCs and we have verified PRU functionality by
loading simple example application (pru_addition.elf) on the PRU cores, by using
"remoteproc" driver from mainline kernel.

Below are the logs for the SOCs with boot log and running PRU with elf file specified
above:

AM335x test log: <https://gist.github.com/ParvathiPudi/87d7ddf949913b80f022ed99706337ac>
AM437x test log: <https://gist.github.com/ParvathiPudi/b2d556829cb4a9e3b6b4c5656dbdd594>


Thanks and Regards,
Parvathi.
