Adding Kbuild CFLAGS. This commit adds all Kbuild CFLAGS to build the kernel binary. Signed-off-by: Juan Manuel Cruz <juan.m.cruz.alcaraz@linux.intel.com> Change-Id: Ia4ca1b71b4e68c4515c428147a8814ca983bb541 2015-02-18 01:16:47 +08:00			`LTO_FLAG-y = $(call cc-option,-flto,)`
Kbuild: Removes the SECTION_GARBAGE_COLLECTION ksymbol. This commit removes from the Kconfig system the SECTION_GARBAGE_COLLECTION kconfig symbols and sets the SECTION_GC_FLAG flag permanently on the compilation options.

Rename option CPU_CORTEXM3 to CPU_CORTEX_M3 Makes name more consistent with CPU_CORTEX_M3_M4 option. Change-Id: I0b89a50a5c0b728167cd76219d25ddf98243c0dd Signed-off-by: Peter Mitsis <peter.mitsis@windriver.com> 2015-06-11 04:16:03 +08:00			`ifeq ($(CONFIG_CPU_CORTEX_M3),y)`
kbuild: Specify -march when using ARM cortex-m3/m4 Some compilers default to a value for -march that is incompatible with the specified -mcpu setting.
