Yes and no ... We have no processes or threads in U-Boot, so we should
have no concurrency here, but you should introduce atomic_long_read()
instead, so we have no difference to linux code. There is already in
U-Boot code atomic.h ... but atomic_long_read() is missing ... so, it
should not so difficult to intriduce this missing function, thanks!
