Anand Gadiyar 963fec4e0f ARM: 6484/1: fix compile warning in mm/init.c
Commit 7c63984b86 (ARM: do not define VMALLOC_END relative to PAGE_OFFSET)
changed VMALLOC_END to be an explicit value. Before this, it was
relative to PAGE_OFFSET and therefore converted to unsigned long
as PAGE_OFFSET is an unsigned long. This introduced the following
build warning. Fix this by changing the explicit defines of
VMALLOC_END to be unsigned long.

Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Jeremy Kerr 0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
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.

Nicolas Pitre 7c63984b86 ARM: do not define VMALLOC_END relative to PAGE_OFFSET
VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
vary depending on the selected user:kernel memory split mode through
CONFIG_VMSPLIT_*.  In fact, the goal of moving PAGE_OFFSET down is to
accommodate more directly addressed RAM by the kernel below the vmalloc
area, and having VMALLOC_END move along PAGE_OFFSET is rather against
the very reason why PAGE_OFFSET can be moved in the first place.

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.

Russell King 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.

Nicolas Pitre 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.
