Emmanuel Vadot	280ab2edb1	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). Reviewed by: jmcneill Differential Revision: https://reviews.freebsd.org/D6383	2016-07-20 11:23:06 +00:00
Jared McNeill	343044c43b	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.

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).
