arm: imx: stop sata on boot
Ideally, the Linux kernel should get the hardware in its most untouched state. For the most part, U-Boot does not reset the various subsystems it touches before boot, and usually Linux deals with it, but on some boards (cm_fx6) the Linux kernel fails to detect the ssd correctly if sata is used by U-Boot. Power off sata on OS boot so that Linux will have a clean state to work with. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Cc: Stefano Babic <sbabic@denx.de>
