DRA7/AM57xx devices can be operated in many different configurations. When the SoC is supposed to support a configuration where low power mode state may involve the SoC completely powered off and DDR is in self refresh, SoC EMIF controller should not be the master of the reset signal and an external entity might be in control of things.
The default configuration of Linux on TI evms involve not powering off the voltage rails (due to various reasons including reliability concerns) and must not allow DDR reset to be controlled by EMIF. On platforms where external entity might control the reset signal, this configuration will be a "dont care".

Applied to u-boot/master, thanks!
