I haven't worked with any of these platforms for many years now, and I can't really say much about their current use. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

I applied the IOP series to to the arm/soc branch now, thanks for the reviews! Arnd -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

I'm looking into converting some of the remaining ARMv5 platforms in arch/arm/ to work together in a single kernel binary. IOP32x seems to be a fairly easy target for multiplatform by itself, but the way the plat-iop code interacts with three generations of the code, and how the dma-adma driver is configured at compile-time for each version gets in the way. I considered adding more indirection layers for those two, but removing iop33x and iop13xx is much easier in comparison, so this is the first approach I'm posting. If we conclude that iop33x and iop13xx are indeed not used any more, the remaining patches in this series are straightforward. The actual multiplatform conversion also requires changes to the irqchip driver that are not completely mechanic, and we can discuss those after deciding what to do with the first set. Adding a few people to Cc that historically worked on IOP.
