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 reprograms MSS to make ROC deal with ordering of MC traffic after boot and system suspend exit. This is needed as device boots with MSS having all control but POR wants ROC to deal with the ordering. Performance is expected to improve with ROC but since no one has really tested the performance, keep the option configurable for now by introducing a platform level makefile variable.

The memory controller loses its settings when the device enters system suspend state. This patch adds a handler to restore the Video Memory settings in the memory controller, which would be called after exiting the system suspend state.

This patch sets the Memory Controller's TXN_OVERRIDE registers for most write clients to CGID_ADR. This ensures ordering is maintained. In some cases WAW ordering problems could occur. There are different settings for Tegra version A01 v A02.

This patch programs the Memory controller's control registers to disable non-secure accesses to the TZRAM. In case these registers are already programmed by the BL2/BL30, then the driver just bails out. Change-Id: Ia1416988050e3d067296373060c717a260499122 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds driver for the Memory Controller (v2) in the newer Tegra SoCs. The newer hardware uses ARM's SMMU hardware instead of the proprietary block in the past. Change-Id: I78359da780dc840213b6e99954e45e34428d4fff Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>
