addition of NEED_MACH_MEMORY_H next to HAVE_IDE.

Sascha Hauer 40c6d8aee4 ARM: 7022/1: allow to detect conflicting zreladdrs
Boards used to specify zreladdr in their Makefile.boot with
zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
This patch changes this to zreladdr-y += x, so that we end
up with multiple words in zreladdr in such a case. We can
detect this later and complain if necessary.

Nicolas Pitre 639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro
Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Ralf Baechle d5341942d7 PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.
Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

The default values for i/o and mem are 0x1000 and 0x01000000, respectively.

This patch makes the various mach dirs that use the plat-orion GPIO
code pass in GPIO-related platform info (GPIO controller base address,
secondary base IRQ number, etc) explicitly, instead of having
plat-orion get those values by including a mach dir include file --

select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

Moreover, due to some implementation problem, I have

Nicolas Pitre a49a018a6e [ARM] add coherent DMA mask for mv643xx_eth
Since commit eb0519b5a1, mv643xx_eth is non functional on ARM because
the platform device declaration does not include any coherent DMA mask
and coherent memory allocations fail.

Nicolas Pitre fdd8b079e3 [ARM] 5460/1: Orion: reduce namespace pollution
Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Lennert Buytenhek f1f5465782 [ARM] mv78xx0: enable eth2/eth3 on the mv78xx0 A0 development board
The A0 revision of the mv78xx0 development board has four ethernet
ports, with PHY IDs 8-11, whereas the Z0 version has two, with PHY
addresses 8-9.  This patch configures the third and fourth ethernet
port to use the PHY addresses on the A0 board to enable use of those
ports -- if we are running on a Z0 board, the ge10/11 setup code in
common.c will force these back to PHYless mode.

Nicolas Pitre fd4b9b3650 [ARM] 5401/1: Orion: fix edge triggered GPIO interrupt support
The GPIO interrupts can be configured as either level triggered or edge
triggered, with a default of level triggered.  When an edge triggered
interrupt is requested, the gpio_irq_set_type method is called which
currently switches the given IRQ descriptor between two struct irq_chip
instances: orion_gpio_irq_level_chip and orion_gpio_irq_edge_chip. This
happens via __setup_irq() which also calls irq_chip_set_defaults() to
assign default methods to uninitialized ones.  The problem is that
irq_chip_set_defaults() is called before the irq_chip reference is
switched, leaving the new irq_chip (orion_gpio_irq_edge_chip in this
case) with uninitialized methods such as chip->startup() causing a kernel
oops.

Many solutions are possible, such as making irq_chip_set_defaults() global
and calling it from gpio_irq_set_type(), or calling __irq_set_trigger()
before irq_chip_set_defaults() in __setup_irq().  But those require
modifications to the generic IRQ code which might have adverse effect on
other architectures, and that would still be a fragile arrangement.
Manually copying the missing methods from within gpio_irq_set_type()
would be really ugly and it would break again the day new methods with
automatic defaults are added.

A better solution is to have a single irq_chip instance which can deal
with both edge and level triggered interrupts.  It is also a good idea
to switch the IRQ handler instead, as the edge IRQ handler allows for
one edge IRQ event to be queued as the IRQ is actually masked only when
that second IRQ is received, at which point the hardware can queue an
additional IRQ event, making edge triggered interrupts a bit more
reliable.
