[PATCH 0/7] ARM: mmp multiplatform support

[PATCH 0/7] ARM: mmp multiplatform support

[Arnd Bergmann]

I've posted this before, this is basically unchanged from the last time
earlier this year, and I'd like to put this into the next/multiplatform
branch of arm-soc for a 4.5 merge. Let me know if you have any concerns
or objections.

Arnd Bergmann (7):
  clk: mmp: stop using platform headers
  ARM: make xscale iwmmxt code multiplatform aware
  ARM: mohawk: allow building with MMU disabled
  ARM: mmp: remove remaining legacy pxa-dma support
  ARM: mmp: make plat-pxa build standalone
  ARM: mmp: make all header files local
  ARM: mmp: move into ARCH_MULTIPLATFORM

[PATCH 1/7] clk: mmp: stop using platform headers

[Arnd Bergmann]

The mmp clock drivers currently hardcode the physical addresses for
the clock registers. This is generally a bad idea, and it also gets in
the way of multiplatform builds, which make the platform header files
inaccessible to device drivers.

To work around the header file problem, this patch changes the calling
convention so the three mmp clock drivers get initialized with the base
addresses as arguments from the platform code.

It would still be useful to have a larger rework of the clock drivers,
with DT integration to let the clocks actually be probed automatically,
and the base addresses passed as DT properties. I am unsure if anyone
is still interested in the mmp platform, so it is possible that this
won't happen.

[PATCH 2/7] ARM: make xscale iwmmxt code multiplatform aware

[Arnd Bergmann]

In a multiplatform configuration, we may end up building a kernel for
both Marvell PJ1 and an ARMv4 CPU implementation. In that case, the
xscale-cp0 code is built with gcc -march=armv4{,t}, which results in a
build error from the coprocessor instructions.

Since we know this code will only have to run on an actual xscale
processor, we can simply build the entire file for ARMv5TE.

Related to this, we need to handle the iWMMXT initialization sequence
differently during boot, to ensure we don't try to touch xscale
specific registers on other CPUs from the xscale_cp0_init initcall.
cpu_is_xscale() used to be hardcoded to '1' in any configuration that
enables any XScale-compatible core, but this breaks once we can have a
combined kernel with MMP1 and something else.

In this patch, I replace the existing cpu_is_xscale() macro with a new
cpu_is_xscale_family() macro that evaluates true for xscale, xsc3 and
mohawk, which makes the behavior more deterministic.

The two existing users of cpu_is_xscale() are modified accordingly,
but slightly change behavior for kernels that enable CPU_MOHAWK without
also enabling CPU_XSCALE or CPU_XSC3. Previously, these would leave leave
PMD_BIT4 in the page tables untouched, now they clear it as we've always
done for kernels that enable both MOHAWK and the support for the older
CPU types.

Since the previous behavior was inconsistent, I assume it was
unintentional.

[PATCH 3/7] ARM: mohawk: allow building with MMU disabled

[Arnd Bergmann]

It is in principle possible to build an MMP kernel for
the mohawk CPU with the MMU code disabled, except for one
simple build error:

proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*ABS* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: invalid operands (*UND* and *UND* sections) for `|'
proc-mohawk.S:345: Error: undefined symbol L_PTE_USER used as an immediate value

This patch changes the proc-mohawk code to do the same as the
other CPUs and not try to actually do anything for the
cpu_mohawk_set_pte_ext function, which won't be used anyway.

ARCH_MULTIPLATFORM already selects this.

Doesn't this file need to be ported over to
arch/arm/include/debug/?

Ok, I'll remove it.

The multiplatform based platforms all use the DEBUG_LL based uncompress
output, which doesn't require the header but is a little more limited
otherwise.

Without these #includes, I get a build error:

Is there anything I need to change here?

Hmph. I seems this broke when we removed the clk.h include from
clk-provider.h, but nobody has noticed for months. Can you make a
different commit to add the header? Otherwise we're sneaking in
that include to get this file to compile again.

Ok, I hadn't noticed at all that it was broken in mainline already,
as the three mmp defconfigs do not use drivers/clk/ at all but instead
rely on arch/arm/mach-mmp/clock*.c instead, which has a separate
implementation.

With the move to multiplatform, the choice goes away and we use the
common clock implementation unconditionally.
