If no boot script was found, expose internal storage over the
USB mass storage gadget to allow easy programming.
This is especially useful when SD cards are inaccessible or when
loading SATA drives.

This patch enables boot to USB storage devices by expanding on the list
of boot devices.
Because the USB startup currently takes a long time, it places USB at
the end of the list of supported devices.
You can over-ride the boot order using the bootdevs environment variable.
For instance, this will make USB the first (highest priority) device:
U-Boot > setenv bootdevs usb mmc sata
U-Boot > saveenv

The HPD pin and RX_SENSE registers have proven to be less reliable
than using I2C on the EDID pins for detection of an HDMI monitor.
In particular, when the HDMI output is reset through a "reboot"
cycle, the detect_hdmi() routine often bounces, resulting in
a failure to detect a connected monitor.

The patch also support the DDR 32-BIT mode option. Please define
CONFIG_DDR_32BIT in the board configure file to enable DDR 32-BIT
mode.But due to the board design, it's 64bit DDR buswidth physically,
so, if you CONFIG_DDR_32BIT, the DDR memory size will be half of it.
