there might be some confusion, because the bcm2835 did have a hardware bugThis is quite common for modern out-of-order CPUs, AFAICT, it is not a hardware bug
lets say you read from the uart, and the gpio, back to back
the hardware bug, would cause the uart read, to return gpio data
and the gpio read would get uart data
and the fix was to insert barriers any time you switch peripherals
