     13  The Meson8/Meson8b/Meson8m2 SoCs have a register bank called SECBUS2 which
     14  contains registers for various IP blocks such as pin-controller bits for
     15  the BSD_EN and TEST_N GPIOs as well as some AO ARC core control bits.
     16  The registers can be accessed directly when not running in "secure mode".
     17  When "secure mode" is enabled then these registers have to be accessed
     18  through secure monitor calls.
