2011-10-17ARM: 7073/1: debug: augment DEBUG_LL Kconfig help to clarify behaviourWill Deacon
Enabled DEBUG_LL hardcodes the UART address into the kernel and results in a non-portable kernel image. Since this option is only intended for use when debugging early boot failures, supporting multiple platforms in such a configuration is not the intended use-case. This patch documents this limitation in the DEBUG_LL Kconfig help text, so that users are aware of the portability restrictions that are associated with enabling low-level debugging support.

2011-10-17ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UARTWill Deacon
Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

2011-10-01ARM: OC_ETM should not select ARM_AMBAArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2011-05-25lib: consolidate DEBUG_STACK_USAGE optionStephen Boyd
Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it to lib/Kconfig.debug so each arch doesn't have to define it. This obviously makes the option generic, but that's fine because the config is already used in generic code. It's not obvious to me that sysrq-P actually does anything caution by keeping the most inclusive wording.

2010-11-19ARM: ftrace: enable function graph tracerRabin Vincent
Add the options to enable the function graph tracer on ARM. Function graph tracer support requires frame pointers, so exclude Thumb-2 and also make sure FRAME_POINTER gets enabled when FUNCTION_GRAPH_TRACER is used, since FUNCTION_TRACER doesn't "select FRAME_POINTER" when ARM_UNWIND is used. Therefore, with GCC 4.4.0+, you get plain function tracing without frame pointers, but you'll need them if you want function graph tracing.
