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.

0560cf5aa5 [ARM] Add a common typesafe __io implementation
As Al did for Versatile in 2ad4f86b60,
add a typesafe __io implementation for platforms to use.  Convert
platforms to use this new simple typesafe implementation.

dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

ccaec3ec78 [ARM] versatile: remove IRQ mask definitions
These definitions are unused and serve no purpose with genirq.

b5ee900258 [ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

71a06da08c [ARM] versatile: convert to clkdev and lookup clocks by device name
People often point to the Integrator/Versatile/Realview
implementations to justify using the consumer name as the sole
selector for clocks.

Eliminate this excuse by changing the Versatile implementation, so
it provides a better example of how it should be done.

1e8b0416ca [ARM] integrator,realview,versatile: remove FLASH_* and EPROM_* constants
FLASH_* and EPROM_* constants are unused, and clash with drivers:

drivers/atm/ambassador.h:257:1: warning: "FLASH_BASE" redefined
drivers/atm/ambassador.h:258:1: warning: "FLASH_SIZE" redefined
drivers/atm/iphase.h:332:1: warning: "EPROM_SIZE" redefined

so remove them.
