PR 833/bsps

  • irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable the FPU across the user ISR but DONT save/restore the FPU context. Any use of the FPU fron the user handler (e.g., due to GCC optimizations) result in corruption. The fix results in an exception in such cases (user ISR must explicitely save/enable/restore FPU).
