ARM: Kconfig: clean up platform selection

The top-level platform selection is mostly meaningless these days after
almost everything is sorted below the CONFIG_ARCH_MULTIPLATFORM, with
the only exception being the 20+ year old StrongARM based machines.

Make this more consistent by removing the entire choice statement and
moving the StrongARM specific options into regular platform specific
Kconfig files.

The three platforms (footbridge, rpc and sa1100) are still mutually
exclusive and cannot coexist with other ARMv4/v5 machines, but since
there are only three of them and we will not add more, this can be
expressed using Kconfig 'depends on' statements.

ARM: rework endianess selection

Choosing big-endian vs little-endian kernels in Kconfig has not worked
correctly since the introduction of CONFIG_ARCH_MULTIPLATFORM a long
time ago.

The problems is that CONFIG_BIG_ENDIAN depends on
ARCH_SUPPORTS_BIG_ENDIAN, which can set by any one platform
in the config, but would actually have to be supported by all
of them.

This was mostly ok for ARMv6/ARMv7 builds, since these are BE8 and
tend to just work aside from problems in nonportable device drivers.
For ARMv4/v5 machines, CONFIG_BIG_ENDIAN and CONFIG_ARCH_MULTIPLATFORM
were never set together, so this was disabled on all those machines
except for IXP4xx.

As IXP4xx can now become part of ARCH_MULTIPLATFORM, it seems better to
formalize this logic: all ARMv4/v5 platforms get an explicit dependency
on being either big-endian (ixp4xx) or little-endian (the rest). We may
want to fix ixp4xx in the future to support both, but it does not work
in LE mode at the moment.

For the ARMv6/v7 platforms, there are two ways this could be handled

a) allow both modes only for platforms selecting
'ARCH_SUPPORTS_BIG_ENDIAN' today, but only LE mode for the
others, given that these were added intentionally at some
point.

b) allow both modes everwhere, given that it was already possible
to build that way by e.g. selecting ARCH_VIRT, and that the
list is not an accurate reflection of which platforms may or
may not work.

Out of these, I picked b) because it seemed slighly more logical
to me.

ARM: use "depends on" for SoC configs instead of "if" after prompt

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7

and

config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent

ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC

This patch allows to build the Kernel for Vybrid (VF6xx) SoC
when ARMv7-M CPU is selected. The resulting image runs on the
secondary Cortex-M4 core. This core has equally access to all
peripherals as the main Cortex-A5 core. However, there is no
resource control mechanism, hence when both cores are used
simultaneously, orthogonal device tree's are required.

The boot CPU is dependent on the SoC variant. The available
boards use mostly variants where the Cortex-A5 is the primary

ARM: imx6: gpc: Add PU power domain for GPU/VPU

When generic pm domain support is enabled, the PGC can be used
to completely gate power to the PU power domain containing GPU3D,
GPU2D, and VPU cores.
This code triggers the PGC powerdown sequence to disable the GPU/VPU
isolation cells and gate power and then disables the PU regulator.
To reenable, the reverse powerup sequence is triggered after the PU
regulator is enabled again.
The GPU and VPU devices in the PU power domain temporarily need
to be clocked during powerup, so that the reset machinery can work.

[Avoid explicit regulator enabling in probe, unless !PM]

irqchip: vf610-mscm-ir: Add support for Vybrid MSCM interrupt router

This adds support for Vybrid's interrupt router. On VF6xx models,
almost all peripherals can be used by either of the two CPU's,
the Cortex-A5 or the Cortex-M4. The interrupt router routes the
peripheral interrupts to the configured CPU.

This IRQ chip driver configures the interrupt router to route
the requested interrupt to the CPU the kernel is running on.
The driver makes use of the irqdomain hierarchy support. The
parent is given by the device tree. This should be one of the
two possible parents either ARM GIC or the ARM NVIC interrupt
controller. The latter is currently not yet supported.

Note that there is no resource control mechnism implemented to
avoid concurrent access of the same peripheral. The user needs
to make sure to use device trees which assign the peripherals
orthogonally. However, this driver warns the user in case the
interrupt is already configured for the other CPU. This provides
a poor man's resource controller.

ARM: Push selects for TWD/SCU into machine entries

The TWD and SCU configs are selected by default as long as

precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those

SCU are no longer selected by default.

Push the select out to the machine entries so that we can compile

ARM: config: sort select statements alphanumerically

As suggested by Andrew Morton:

This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.

Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically. This commit was
created by the following perl:

while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

As audmux becomes a platform driver and its callers are all ASoC

move it to sound/soc/imx.

One bonus point would be those ASoC machine drivers stop including

imx6q: Remove unconditional dependency on l2x0 L2 cache support

The i.MX6 Quad SoC will work without the l2x0 L2 cache controller
support built into the kernel, so this patch removes the dependency
on CACHE_L2X0.

This makes the l2x0 support optional, so that it can be turned off
when desired for debugging purposes etc.

Since SOC_IMX6Q already depends on ARCH_IMX_V6_V7 and
ARCH_IMX_V6_V7 selects MIGHT_HAVE_CACHE_L2X0, there is no need to
select that option explicitly from SOC_IMX6Q.

Thanks to Shawn Guo for this suggestion. [1]

letting them select other symbols makes the logic more complex and needs
to duplicate some things. So let the machines select the corresponding

ARM: imx: new Kconfig symbol and feature test macro for DMA on mx1 and mx2

This should be used instead of hard coding the corresponding platforms.
The feature test macro is needed to support different SOCs in a single
kernel image. While at it rename dma-mx1-mx2 to dma-v1 as mx25 doesn't
use it and so the mx2 part is wrong and move the header to
arch/arm/mach-imx.

ARM: imx: prepare deprecating ARCH_MX1, MACH_MX2, MACH_MX21 and MACH_MX27

MACH_... is reserved for machine support, so use SOC as prefix, not MACH.

This introduces new symbols SOC_IMX1, SOC_IMX21 and SOC_IMX27. They are
selected by the old symbols for now. There is no substitute for MACH_MX2
as most usages of MX2 only means MX21 + MX27 but not MX25.

Later the choice about CPU and CPU family should go away and the individual
machines should select the right SOC symbol. This is a precondition to
support more than one SOC in a single kernel image.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
