Hi David,
thanks for testing!

I am still blocking my machine with the build scripts :)
So I have not had a chance to test it on any hardware.

Yes, dma32 vs. dma64 bit was recently a problem, also for omap with LPAE.

Well, my LPAE build did succeed but it may be that my compiler isn't
that critical (-Werror=incompatible-pointer-types) and just did emit
an unnoticed warning.

Yes, no problem.

Maybe Andreas knows what to do for i.MX (Kobo/Tolino e-book reader).

BR and thanks,
