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.

Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com>
and Tony Lindgren <tony@atomide.com>, and fix for versatile express from
Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.

Anton Vorontsov 5f32f7a028 ARM: cns3xxx: Add support for PCI Express ports
This patch adds PCIe support for CNS3xxx-based boards. The support
was tested with a directly attached SKY2 NIC, and EHCI USB controller
behind the PLX PEX8112 P2P bridge (to make sure that type1 cfg cycles
work as expected).

Anton Vorontsov 6eb5d146d4 ARM: cns3xxx: Use IO memory accessors everywhere
Before it isn't too late let's switch to IO memory accessors.
This patch converts all current _REG users and _REG definitions.
There should be no functional changes.

Anton Vorontsov d94f944e10 ARM: cns3xxx: Add basic support for Cavium Networks CNS3xxx processors
This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.

Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.
