Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Arnd Bergmann e05dd97c5c Merge tag 'at91-for-next-soc' of git://github.com/at91linux/linux-at91 into at91/mci
AT91 SoC related code modifications: a cleanup in defconfigs and
a one liner in a board file.
The most important is the move to atmel-mci driver in AT91 SoC & boards.
The old at91_mci (marked as deprecated) will be removed in 3.7. So all
platform data for this old driver are erased and replace by information
needed by atmel-mci driver.

* tag 'at91-for-next-soc' of git://github.com/at91linux/linux-at91:
  ARM: at91: add atmel-mci support for chips and boards which can use it
  ARM: at91/defconfig: change the MCI driver to use in defconfigs
  ARM: at91: set i2c_board_info.type to "ds1339" directly
  ARM: at91/defconfig: Remove unaffected config option

Ludovic Desroches 4cf3326ab5 ARM: at91: add atmel-mci support for chips and boards which can use it
Since atmel-mci driver supports all atmel mci versions,
use it instead of the deprecated at91_mci driver.
Platform data and all related configuration are removed.

Jean-Christophe PLAGNIOL-VILLARD 71b149b3f7 ARM: at91: do not pin mux the UARTs in init_early
There is no need to pinmux the UART so early in the kernel.
Move it to the board init.

This will also allow to finally move the gpio driver to platform device/driver.

Jean-Christophe PLAGNIOL-VILLARD a27fa58117 ARM: at91: drop at91_set_serial_console
at91_set_serial_console is used to define the default console of linux.
This is already manage by the cmdline. And if the boot loader can not be
modified you can still set it by enabling the CONFIG_CMDLINE_EXTEND option.
And then the command-line arguments provided by the boot loader will be
appended to the default kernel command string.

Jean-Christophe PLAGNIOL-VILLARD 21d08b9d55 at91: introduce commom AT91_BASE_SYS
On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.

On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000

This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space

select ARM_PATCH_PHYS_VIRT
as with ARM_PATCH_PHYS_VIRT you can patch boot_params at runtime or any recent
bootloader will provide a valid atags pointer in r2

as point out by Russell on AT91 we never use XIP
so se do not need PLAT_PHYS_OFFSET

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 ]
