Commit (20fae0a - ARM: DRA7: DDR: Enable SR in Power Management Control) enables Self refresh mode by default and during warm reset the EMIF contents are preserved. After warm reset EMIF sees that it is idle and puts DDR in self-refresh. When in SR, leveling operations cannot be done as DDR can only accept SR exit command, so its hanging during warm reset. In order to fix this reset the power management control register before EMIF initialization if it is a warm reset.
