They have not; but then, there shouldn't be anything new required in order to support the i2ultra, since the version of the code I pulled from already had support for all four boards. > It is a bit difficult, as their version is based on 2013.10-rc4, while > Debian is following upstream with 2014.04 and 2014.07-rc4. Yes. If there's an incompatibility here that's not seen with the SolidRun tree, it's probably due to an underlying difference between 2013.10 and 2014.04 that I failed to account for when forward-porting, since I only have an i4 to test on. None of the newer commits on the upstream branch look to have anything to do with the i2-ultra. > But yes, 2014.07-rc4 appears to include support for SPL on imx6, although > the only board using it is gw_ventana.

I haven't yet; I would assume that Rainer would be using unstable rather than experimental if he's trying to get this booting for the first time with Debian. As for upstreaming, the patches were split the way they were in order to facilitate such upstreaming but while I've pointed SolidRun at my work to split the patches (and my rebasing work), I don't know that anyone's made a serious effort at pushing these upstream yet. https://github.com/vorlonofportland/u-boot/tree/2014.04-SPL-SATA https://github.com/vorlonofportland/u-boot/tree/2014.04-imx6-SPL-support https://github.com/vorlonofportland/u-boot/tree/2014.04-cubox-i-support I suppose if you've got 2014.07-rc4 in experimental now, that implies you've forward-ported the patches and I should have a look at providing updated branches. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
