A little background is probably appropriate for this patch.
Since "the beginning" of usage of the SABRE Lite and Nitrogen6x
boards, DVI detection has been somewhat broken.
Some (most) DVI monitors don't produce the "HPD" bit in
the PHY_STAT0 register, but do show proper toggling of the
RX_SENSE0..3 bits.
Creating a new the bit-mask to include all five bits and
modifying the 'hdmidet' command and internal detection
routines allows these monitors to function properly in U-Boot.
A related patch to our kernels allows things to work under
Linux:

This is useful for forcing the ROM's
usb downloader to activate upon a watchdog reset.
Or, you can boot from either SD Card.
Currently, support added for MX53 and MX6Q
