Subject: [PATCH 00/12] ARM: ARMv5 multiplatform conversions
From: Arnd Bergmann <arnd@...db.de>
I revisited some patches from a few years back, to see what
is needed forsome of the remaining platforms to become part of
CONFIG_ARCH_MULTIPLATFORM.
A few things happened since I last looked at this, which helps to make
this easier:
- The ixp4xx platform saw a large scale cleanup
- The ep93xx platform lost support for MaverickCrunch FPUs and
gained support for the common clock subsystem
- The OMAP1 platform has a proposed patch for the common
clock subsystem.
- The generic IRQ entry code is now used everywhere, including
on IOP32x.
- The s3c24xx platform is scheduled for removal next year
It appears that we can now convert almost all the remaining platforms
(ep93xx, dove, s3c24xx, iop32x and ixp4xx), leaving only:
- OMAP1 has a separate series, since the conversion is non- trivial,
and depends on the clk conversion from Janusz Krzysztofik. I'll
post that separately.
- PXA needs an even longer series, which I've also sent in the past,
but I'll keep that for later.
- The three StrongARM based platforms remain quite different from
the rest, and I expect that to stay this way, until they are
eventually removed from the tree.
For simplicity I'd want to merge the series directly through the
soc tree, provided there are no regressions or other concerns
with the patches.
