The CONFIG_ARM_AMBA symbol is selected by the platforms that support
AMBA, and the other platforms (e.g. orion) might not be able to
build that code at all when they do not support the clk API.
Instead, make sure that OC_ETM is only built on platforms that
do support the amba subsystem already.

Some PCI drivers call pcibios_bus_to_resource directly,
but it is only exported when CONFIG_HOTPLUG is set,
because it was initially mean for pccard support.
Moving the export out of the #ifdef lets us avoid these

Support for IDE drivers should not be automatic, since most platforms
cannot actually support any IDE low-level drivers. This partly
reverts 2064c946e "ARM: always select HAVE_IDE" to set this symbol
only when either a PC-style bus (PCI, ISA, PCMCIA) is enabled or
a platform is used that is known to have an existing driver in
drivers/ide.
New platforms should not need this option and just use CONFIG_ATA
with drivers/ata/.

Thumb2 kernels cannot be built with frame pointers, but can use the
ARM_UNWIND feature for unwinding instead. This makes sure that all
features that rely on unwinding includeing CONFIG_LATENCYTOP and
FAULT_INJECTION_STACKTRACE_FILTER do not enable frame pointers
when the unwinder is already selected, and we always build with
the unwinder when we want a thumb2 kernel, to make sure we do not
get the frame pointers instead.
A different option would be to redefine the CONFIG_FRAME_POINTERS
option on ARM to mean builing with either frame pointers or
the unwinder, and then select which one to use based on the
CPU architecture or another user option. That would still allow
building thumb2 kernels without the unwinder but would also be
more confusing.

Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for
MMC1_PBIAS and associated extended-drain MMC1 I/O cell. This is in accordance
with the control module programming guide. This fixes a bug where if trying to
use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be
affected by a changing SDMMC1_VDDS.
Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever
SDMMC1_VDDS ramps up/down or changes for cell protection purposes.
MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore
they can operate independently.

arch/arm/mach-omap2/board-4430sdp.c can be used to set the backlight to
