David Brownell e0b50d3c64 ARM: OMAP: partial LED fixes
Partial fix for CONFIG_LEDS breakage ... at least allow platforms
using the debug-leds support (H4 for now) to build with the generic
LED support, and default the LED that would be the timer LED to
trigger using the "heartbeat" (timer driven, rate depends on load).

Right now only H2 and P2 seem to have working LED support; this
at least makes H4 less broken.

David Brownell 994c84ea52 ARM: OMAP: h4 must have blinky leds!!
This adds generic support for the "debug board" LEDs used by most of
TI's OMAP reference boards, and board-specific support for the H4.

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2.
Those should be able to switch easily to this version, and clean up
some of the omap1-specific code.

In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that
can be handy for kernel debugging), but it also supports the "new"
generic LED API (most useful for usermode stuff IMO).  Either or both
APIs can be enabled.

Russell King 8678c1f042 [ARM] Fix ASID version switch
Close a hole in the ASID version switch, particularly the following
scenario:

CPU0 MM PID			CPU1 MM PID
	idle
				  A	pid(A)
				  A	idle(lazy tlb)
		* new asid version triggered by B *
  B	pid(B)
  A	pid(A)
		* MM A gets new asid version *
  A	idle(lazy tlb)
				  A	pid(A)
		* CPU1 doesn't see the new ASID *

The result is that CPU1 continues running with the hardware set
for the original (stale) ASID value, but mm->context.id contains
the new ASID value.  The result is that the next MM fault on CPU1
updates the page table entries, but flush_tlb_page() fails due to
wrong ASID.

There is a related case with a threaded application is allocated
a new ASID on one CPU while another of its threads is running on
some different CPU.  This scenario is not fixed by this commit.

Christoph Hellwig 1eeb66a1bb move die notifier handling to common code
This patch moves the die notifier handling to common code.  Previous
various architectures had exactly the same code for it.  Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)

arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at.  avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

Russell King 3603ab2b62 [ARM] mm 10: allow memory type to be specified with ioremap
__ioremap() took a set of page table flags (specifically the cacheable
and bufferable bits) to control the mapping type.  However, with
the advent of ARMv6, this is far too limited.

Replace the page table flags with a memory type index, so that the
desired attributes can be selected from the mem_type table.

Finally, to prevent silent miscompilation due to the differing
arguments, rename the __ioremap() and __ioremap_pfn() functions.

David Brownell 11a78b7944 ARM: OMAP: MPUIO wake updates
GPIO and MPUIO wake updates:

 - Hook MPUIOs into the irq wakeup framework too.  This uses a platform
   device to update irq enables during system sleep states, instead of
   a sys_device, since the latter is no longer needed for such things.

 - Also forward enable/disable irq wake requests to the relevant GPIO
   controller, so the top level IRQ dispatcher can (eventually) handle
   these wakeup events automatically if more than one GPIO pin needs to
   be a wakeup event source.

 - Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
   read-only data under the spinlock.

This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.

Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong:  omap1
saves the flags but ignores them, omap2 doesn't even save it.  (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

  - remove all BUG() calls, which are always bad news ... replaced some
    with normal fault reports for that call, others with WARN_ON(1).

  - small mpuio bugfix:  add missing set_type() method

Oh, and fix a minor merge issue: inode->u.generic_ip is now gone.

David Brownell b9772a220a ARM: OMAP: /sys/kernel/debug/omap_gpio
Add some GPIO debug support:  /sys/kernel/debug/omap_gpio dumps the state
of all GPIOs that have been claimed, including basic IRQ info if relevant.
Tested on 24xx, 16xx.

Includes minor bugfixes:  recording IRQ trigger mode (this should probably
be a genirq patch), adding missing space to non-wakeup warning

Juha Yrjola 3ac4fa9929 ARM: OMAP: Implement workaround for GPIO wakeup bug in OMAP2420 silicon
Some GPIOs on OMAP2420 do not have wakeup capabilities. If these GPIOs
are configured as IRQ sources, spurious interrupts will be generated
each time the core domain enters retention.

Michael-Luke Jones 28bd3a0dcc [ARM] 4318/2: DSM-G600 Board Support
This patch adds support for the D-Link DSM-G600 Rev A.
This is an ARM XScale IXP4xx system relatively similar to
the NSLU2 and NAS-100D already supported by mainline. An
important difference is Gigabit Ethernet support using
the Via Velocity chipset.

This patch is the combined work of Michael Westerhof and
Alessandro Zummo, with contributions from Michael-Luke
Jones. This version addresses review comments from rmk
and Deepak Saxena.

Nicolas Pitre 4043579252 [ARM] 4227/1: minor head.S fixups
Let's surround constructs like:

	orr	r3, r3, #(KERNEL_RAM_PADDR & 0x00f00000)

between .if .endif since (KERNEL_RAM_PADDR & 0x00f00000) is 0 in 99% of
all cases.

Also let's mask PHYS_OFFSET with 0x00f00000 instead of 0x00e00000.
Section mappings are really 1MB not 2MB and the 2MB groupping is
a higher level issue already much better enforced with

#if (PHYS_OFFSET & 0x001fffff)
#error "PHYS_OFFSET must be at an even 2MiB boundary!"
#endif

at the top of the file.
