rtos: Freescale MQX rtos support
ARMv7E-M (CortexM4) architecture - fix position offset of r2,r3 registers on exception stack - switch 'calloc' arguments - remove prototypes of internal function and typedefs - add NULL check for alloc functions - remove last line of license "Franklin Street, Fifth Floor" because of 'checkpatch' validation - environment: jlink + twrk60n512 Change-Id: I70840ded15b17dd945ca190ce31e2775078da2d9 Signed-off-by: Marian Cingel <cingel.marian@gmail.com> Reviewed-on: http://openocd.zylin.com/2353 Tested-by: jenkins Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk>
