And you can reproduce the bug with gcc5 or gcc6?

Very strange that a DT only patch would cause a gcc related regression
and if it does, it should be investigated.  I don't think requiring
gcc7 is an appropriate solution.

@Chen-Yu, @Maxime: are you guys OK with requiring gcc7 for working
upstream boot for A10?
