c++11 std::atomic

[Mikhail Svetkin]

I have figured out.

I used my own BSP (stm32f7).
It happend only with SDRAM.
The example worked correctly with internal flash.

Also i wrote a small inline asm functions for atomic
operations(increment/decrement).
They both worked correctly with internal RAM.
They worked correctly in bsp_hook, bsp_start, but they did not work in Init
function(I recived _ARMV7M_Exception_default) with SDRAM.

I think i have problem with MPU configuration
