[yocto-ab] Fwd: Re: [yocto] anyone building for the arrow sockit eval board?

[Philip Balister]

Is anyone in contact with Altera about an "official" BSP? It would be
good to get them pointed in the proper direction before several
community layers pop up.

The interesting ones in there are meta-altera and meta-linaro; it would
also be interesting to see if anything else is modified or if it is
vanilla Yocto. I have a sinking feeling it may not be... mainly due to
the tightly coupled DT and socfpga implementation with the Altera tools.

Could you post the altera-init script; I would imagine that hides the
demons ;)
