ARM: zynq: add support for ARCH_MULTIPLATFORM The majority of changes are necessary to remove dependencies on header files within arch/arm/mach-zynq/include/mach: uncompress.h - Deleted. It is unused for ARCH_MULTIPLATFORM builds. uart.h: - Move uart definitions out of uart.h into debug/zynq.S, which is now the only user zynq_soc.h: - Move SCU address definitions into common.c. - Other #defines, such as PERIPHERAL_CLOCK_RATE, TTC0_BASE, etc, are unused and can be dropped Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Tested-by: Michal Simek <michal.simek@xilinx.com> 2012-11-19 11:38:29 -06:00			`config ARCH_ZYNQ`

ARM: Push selects for TWD/SCU into machine entries The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

ARM: smp_twd: Divorce smp_twd from local timer API Separate the smp_twd timers from the local timer API. This will allow us to remove ARM local timer support in the near future and gets us closer to moving this driver to drivers/clocksource.
