Thanks to help from Tony, Suman, Nishanth, and Tero, some of the earlier test failures in the v4.1-rc series have been tracked down. The 4460 VAR-SOM-OM was booting with an older DT file since the point in time last year when the DT file was renamed; this has now been fixed. Most of the other failures were due to timeout problems after commit cc4a5fe972ad7834e8662b49b3a5fdb597e9e15e ("arm: config: omap2plus_defconfig: switch over to LZMA compression") which pushed the time interval from the point at which the "Starting kernel" message is emitted to the point at which the kernel starts to log serial output to the console over 5 seconds on many OMAP3 and earlier platforms. From my point of view this commit is a mistake. Anyone integrating a kernel into a consumer device will need to be sure to disable LZMA compression if reasonable boot times are desired. This is not something that the vast majority of integrators will be aware of.

The 5430es2sbct54 is still not booting to userspace; this is on the list here to bisect.
