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