My primary aim was to reduces the diff against the downstream fork, to
make upstream work just as well.
But the HS200/400 mode is not used by those two boards, but by:
And my other patch for espressobin-emmc is using it too. They're
independent, so it works without it, just not as fast.
Having said that, I don't have either of those boards, so I haven't
tested it myself. But the patches have been downstream for over two
years, so I'd say they're well tested since everybody runs a downstream
firmware (which will hopefully change now ;)
