Russell King b1b3f49ce4 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.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

Linus Torvalds 9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

This is a large branch that contains a handful of different cleanups:
 
 - Fixing up the I/O space remapping on PCI on ARM. This is a series
   from Rob Herring that restructures how all pci devices allocate I/O
   space, and it's part of the work to allow multiplatform kernels.
 - A number of cleanup series for OMAP, moving and removing some
   headers, sparse irq rework and in general preparation for
   multiplatform.
 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra

While I was at it, I also made the dtb generation more generic, i.e. if
the platform is enabled then all dtbs for that platform will be created.

 Multi-platform support is dependent on mach/gpio.h removal and
 restructuring of DEBUG_LL and dtb build rules included in this branch.
 
 This has been built for all defconfigs, and booted on highbank with

Stephen Boyd 4312a7ef9c ARM: msm: Allow timer.c to compile on multiple targets
The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.

This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.

The uart mapping runs into the space allocated for lowmem on some
8960 boards when we have more than 512Mb of memory. We were
getting lucky before and our mapping wasn't part of DDR. Move the
mapping up into the vmalloc area which will always be outside of
the lowmem mapping regardless of how much lowmem actually exists.

Forcing arm_pm_idle to be msm_idle() doesn't make sense in
configurations that don't have CONFIG_MSM7X00A_IDLE=y (i.e. any

exist, so this entire file is dead code. Just remove it so we can
use the default idle support on MSM.

Rohit Vaswani 90eb385fd1 ARM: msm: io: Change the default static iomappings to be shared
With 3.4 kernel the static iomappings can be shared with the ioremap
mappings. If ioremap is called with an address for which a static
mapping already exists, then that mapping should be used instead
of creating a new one.

However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid
of this flag. Some targets (7X00) that require the static iomappings
to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.

David Brown 49b26e0dfd ARM: msm: Remove call to missing FPGA init on 8660
A previous patch[1] added code to initialize an FPGA register on the
8660 "SURF" development platform.  Since this development platform is
not widely available, and there is now a more available device "the
Dragonboard" based on the same core SOC, this change was dropped.

However, the DT code kept a lingering call to this FPGA init function.
Remove it.

Linus Torvalds f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.
