Applying an unmaintained intrusive patch from 2010 is not really a
realistic option. Did you try the alternative proposed in the mailing
E.G. add something like this to your overlay:
Then the u-boot defconfig option should afaik default to that.
But I am not quite sure why you would want to do this in the first place
instead of just providing a defconfig file with the right options set?
