[PATCH 2/2] ARM: imx: Enable SDP download in SPL on DH i.MX6 DHSOM

[sbabic at denx.de]

> Enable SDP protocol support in SPL for DH i.MX6 DHSOM, now that those
> components fit into the SPL due to LTO.
> To start U-Boot via SDP upload on i.MX6 DHSOM based board, proceed as follows:
> - Compile imx_usb [1] .
> - Power off the i.MX6 DHSOM based board.
> - Connect both USB-serial console and USB-OTG miniB ports to host PC.
> - Switch board to USB boot mode.
> - Power on the board.
> - Verify using '$ dmesg' that a new device has been detected as follows:
>     New USB device found, idVendor=15a2, idProduct=0054, bcdDevice= 0.01
>     New USB device strings: Mfr=1, Product=2, SerialNumber=0
>     Product: SE Blank ARIK
>     Manufacturer: Freescale SemiConductor Inc
> - Upload U-Boot SPL:
> $ imx_usb u-boot-with-spl.imx
> - Wait for SPL to come up, the following print ought to be the last on
>   UART console:
> SDP: handle requests...
> - Upload U-Boot proper:
> $ imx_usb u-boot.img
> [1] https://github.com/boundarydevices/imx_usb_loader.git
