Subject: [PATCH 0/7] ARM: preparation for multiplatform iop32x
Date: Fri, 9 Aug 2019 18:29:41 +0200 [thread overview]
Message-ID: <20190809162956.488941-1-arnd@arndb.de> (raw)
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.

Arnd Bergmann (7):
[RFC] ARM: remove Intel iop33x and iop13xx support
dma: iop-adma: include prefetch.h
dma: iop-adma: use correct printk format strings
dma: iop-adma: allow building without platform headers
ARM: xscale: fix multi-cpu compilation
ARM: iop32x: make mach/uncompress.h independent of mach/hardware.h
ARM: iop32x: merge everything into mach-iop32x/
