ARM: ftrace: enable function graph tracer 2010-11-19T16:13:28+00:00 Rabin Vincent rabin@rab.in 2010-11-06T17:33:53+00:00 0e341af835fdf553820a1fa98341b93ab32ce466 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.

ARM: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/mem

There are very few legitimate use cases, if any, for directly accessing
system RAM through /dev/mem.  So let's mimic what they do on x86 and
forbid it when CONFIG_STRICT_DEVMEM is turned on.

With a new enough GCC, ARM function tracing can be supported without the
need for frame pointers.  This is essential for Thumb-2 support, since
frame pointers aren't available then.

ARM: SAMSUNG: Move plat-s3c Kconfig entries to plat-samsung and plat-s3c24xx

Move the Kconfig entries from plat-s3c to plat-samsung and plat-s3c24xx
as necessary. The S3C_BOOT entries and the DMA configuration can go to
plat-samsung. The low-level UART configurations are currently S3C2XX
specific and can go to plat-s3c24xx.

Eliminating plat-s3c from the build process will be submitted seperately.

This patch allows an earlyprintk console if CONFIG_DEBUG_LL is enabled,
using the printch asm function.

The patch is based on the original work by Sascha Hauer.
