Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull arm soc-specific updates from Arnd Bergmann:
 "This is stuff that does not fit well into another category and in
  particular is not related to a particular board.  The largest part in
  here is extending the am33xx support in the omap platform."

Fix up trivial conflicts in arch/arm/mach-{imx/mach-mx35_3ds.c, tegra/Makefile}

The uncompressor code port configuration is now handled
by CONFIG_S3C_LOWLEVEL_UART_PORT.
config DEBUG_VEXPRESS_UART0_DETECT
bool "Autodetect UART0 on Versatile Express Cortex-A core tiles"
depends on ARCH_VEXPRESS && CPU_CP15_MMU
help
This option enables a simple heuristic which tries to determine
the motherboard's memory map variant (original or RS1) and then
choose the relevant UART0 base address.
Note that this will only work with standard A-class core tiles,
and may fail with non-standard SMM or custom software models.
config DEBUG_VEXPRESS_UART0_CA9
bool "Use PL011 UART0 at 0x10009000 (V2P-CA9 core tile)"
depends on ARCH_VEXPRESS
help
This option selects UART0 at 0x10009000. Except for custom models,
this applies only to the V2P-CA9 tile.
config DEBUG_VEXPRESS_UART0_RS1
bool "Use PL011 UART0 at 0x1c090000 (RS1 complaint tiles)"
depends on ARCH_VEXPRESS
help
This option selects UART0 at 0x1c090000. This applies to most
of the tiles using the RS1 memory map, including all new A-class
core tiles, FPGA-based SMMs and software models.
