* sunxi: Support Secure Memory Touch Arbiter (SMTA) in sun8i H3Chen-Yu Tsai2016-01-26-1/+10
| | | | | | | | | | | | | | | Secure Memory Touch Arbiter is the same thing as the TrustZone Protection Controller found on A31/A31s. Access to many peripherals on the H3 can be controlled by the SMTA, and the settings default to secure access only. This patch supports the new settings, and sets them to allow non-secure access.

* sunxi: Enable non-secure access to RTC on sun6i (A31s)Chen-Yu Tsai2015-08-31-0/+18
On the A31s the RTC is by default secured. Thus when u-boot loads the kernel in non-secure world, the RTC is unavailable. The SoC has a TrustZone Protection Controller, which can be used to enable non-secure access to the RTC. On the A31 the TZPC doesn't seem to do anything, i.e. changes to its register contents do not affect access to the RTC.
