 iMX6s are 45nm Quad Cortex A9s, and freescale (guessing here) may
have picked the "performance"option on hard macros which means they
need *four amps* on start-up, and need quite a lot of power running
100% CPU.  theres a app note on power consumption by freescale and
they mention a worst-case scenario but i think this is well below
that.
