Aijun Sun ab609e1a76 trusty: save/restore FPU registers in world switch ... Currently, Trusty OS/LK implemented FPU context switch in internal thread switch but does not implement the proper mechanism for world switch. This commit just simply saves/restores FPU registes in world switch to prevent FPU context from being currupted when Trusty OS uses VFP in its applications. It should be noted that the macro *CTX_INCLUDE_FPREGS* must be defined in trusty.mk if Trusty OS uses VFP Signed-off-by: Aijun Sun <aijun.sun@spreadtrum.com>		2017-09-19 19:20:48 +08:00
