+- Freescale i.MX specific commands:
+               CONFIG_CMD_HDMIDETECT
+               This enables 'hdmidet' command which returns true if an
+               HDMI monitor is detected.  This command is i.MX 6 specific.
+
+               CONFIG_CMD_BMODE
+               This enables the 'bmode' (bootmode) command for forcing
+               a boot from specific media.
+
+               This is useful for forcing the ROM's usb downloader to
+               activate upon a watchdog reset which is nice when iterating
+               on U-Boot.  Using the reset button or running bmode normal
+               will set it back to normal.  This command currently
+               supports i.MX53 and i.MX6.
