Add support for the SID (Security ID Module) on Allwinner A10 and A20.
The rootkey is burnt at production and can't be changed, thus is can be used
as a device unique ID or to generate a MAC address
Add support for the SID (Security ID Module) on Allwinner A10 and A20.
The rootkey is burnt at production and can't be changed, thus is can be used
as a device unique ID or to generate a MAC address (This is was u-boot does).
The rootkey is exposed as a sysctl (dev.aw_sid.<unit>.rootkey).

Add Allwinner A83T thermal sensor controller support.
The A83T thermal sensor controller has three sensors. Sensor 0 corresponds
to CPU cluster 0, sensor 1 to CPU cluster 1, and sensor 2 to the GPU.
Add Allwinner A83T thermal sensor controller support.
The A83T thermal sensor controller has three sensors. Sensor 0 corresponds
to CPU cluster 0, sensor 1 to CPU cluster 1, and sensor 2 to the GPU. This
driver exports the temperature sensor readings via sysctl.
Calibration data is obtained from SRAM found in the Secure ID module.
