> A lot of these patches are ready to commit and not dependent on the QUP stuff (which I assume will still take a while). If you reorder them to the front we could already get them out of the way?

We re-ordered the patch-train like this:
 * libpayload header file (only patch that doesn't depend on clock and/or qup)
 * clock patch
 * all patches that depend on clock patch (most/all of these are +2)
 * qupV3 FW patch
 * all patches that depend on qupV3 FW patch
 * everything else
