Subject: imx: kontron-sl-mx8mm: Enable SDP support for loading via USB
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c1cd4f3806b8873ce96c46572e7aaacd419307f4;p=thirdparty%2Fu-boot.git

imx: kontron-sl-mx8mm: Enable SDP support for loading via USB

Enable everything that is required to load via USB. The SPL needs
SDP support so it can load the U-Boot proper image via USB after
it has been loaded via serial loader mode of the i.MX.

This way we can use the uuu tool for loading SPL and U-Boot
proper like this:

  uuu -brun flash.bin
