Hi Tom,

I have posted the ESM patches to the linux kernel device tree mailing

Keerthy (2):

Correct the min/max voltages of VDD_CPU. As per data sheet the VDD_CPU
minimum voltage is .6V & maximum voltage is .9V.
Correct the same. While at it fix the comment to reflect VDD_CPU
instead of VDD_MPU.

Add MAIN domain R5FSS0 remoteproc support from spl. This enables
loading the elf firmware in SPL and starting the remotecore.
In order to start the core, there should be a file with path
"/lib/firmware/j7-main-r5f0_0-fw" under filesystem
of respective boot mode.

In case only CONFIG_ENV_IS_NOWHERE without any of the memory
based configs like CONFIG_ENV_IS_IN_MMC the env_set function
fails as the gd->flags & GD_FLG_ENV_READY check fails.
Set default enviroment so that set_env calls succeed when only
ENV_IS_NOWHERE set.
