This patch empowers the platforms to provide the settings (e.g. stream ID, security setting, transaction overrides) required by the Memory Controller driver. This allows the platforms to program the Memory Controller as per their needs and makes the driver scalable.

This patch moves the smmu driver introduced by the Tegra186 port to tegra/common so that future chips can (re)use it. Change-Id: Ia44c7f2a62fb2d8869db3a44742a8c6b13c49036 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds support to save the BL31 state to the TZDRAM before entering system suspend. The TZRAM loses state during system suspend and so we need to copy the entire BL31 code to TZDRAM before entering the state. In order to restore the state on exiting system suspend, a new CPU reset handler is implemented which gets copied to TZDRAM during boot. TO keep things simple we use this same reset handler for booting secondary CPUs too. Change-Id: I770f799c255d22279b5cdb9b4d587d3a4c54fad7 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds a device driver for the SMMU hardware block on Tegra186 SoCs. We use the generic ARM SMMU-500 IP block on Tegra186. The driver only supports saving the SMMU settings before entering system suspend. The MC driver and the NS world clients take care of programming their own settings.
