I wonder how Crochet should handle this. Plenty of = folks use Crochet to build 10-STABLE and 10.1 images, so we have to be a = little careful about jumping ahead with new features that are only = available in 11-CURRENT. >>>=20 >>> Any plans to MFC this? >>>=20 >>> Tim >>=20 >> It has all been MFC'd to 10-stable around the end of May and will be = in >> 10.2.

Oh, I see. So you=E2=80=99re going to change the U-Boot ports to load ubldr.bin instead of ubldr. Which in turn means that people building images will need to install ubldr.bin. I=E2=80=99m testing Crochet changes to use the U-Boot ports right now (for RPi and BB). Before I push those, I should probably adjust things so I=E2=80=99m installing both ubldr and ubldr.bin. That way, I=E2=80=99ll be proof against the U-Boot port changes as they land. Tim P.S. I suppose this will completely break building 10.1 images based on U-Boot ports, since 10.1 doesn=E2=80=99t have ubldr.bin. Hmmm=E2=80=A6
