cd1cc8282d ARM: S3C: Change VMALLOC_END to use more vmalloc()/ioremap() area
This patch changes VMALLOC_END from 0xE0000000 to 0xF6000000, because
some systems want to use more vmalloc()/ioremap() area and now don't use
from at 0xE0000000 to 0xF6000000 (the start of Samsung SoCs' VA space)

e0e451ea09 ARM: S3C24XX: Fix gpiolib support for ports K..M
S3C2443 and S3C2416 has 12 GPIO banks (from A to M), increase
ARCH_NR_GPIOS for this architectures.

Also typo from previous commit has been fixed: CONFIG_CPU_S3C24XX
instead CONFIG_CPU_244X.

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 ]

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.
