Varun Wadekar	9a9645105b	Reserve a Video Memory aperture in DRAM memory This patch adds support to reserve a memory carveout region in the DRAM on Tegra SoCs. The memory controller provides specific registers to specify the aperture's base and size. This aperture can also be changed dynamically in order to re-size the memory available for DRM video playback. In case of the new aperture not overlapping the previous one, the previous aperture has to be cleared before setting up the new one. This means we do not "leak" any video data to the NS world.

Varun Wadekar	dc7fdad251	Boot Trusted OS' on Tegra SoCs This patch adds support to run a Trusted OS during boot time. The previous stage bootloader passes the entry point information in the 'bl32_ep_info' structure, which is passed over to the SPD. The build system expects the dispatcher to be passed as an input parameter using the 'SPD=<dispatcher>' option. The Tegra docs have also been updated with this information.

Varun Wadekar	08438e24e1	Support for NVIDIA's Tegra T210 SoCs T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active at a given point in time. This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch also adds support to boot secondary CPUs, enter/exit core power states for all CPUs in the slow/fast clusters. The support to switch between clusters is still not available in this patch and would be available later. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>	10 years ago

Reserve a Video Memory aperture in DRAM memory

This patch adds support to reserve a memory carveout region in the
DRAM on Tegra SoCs. The memory controller provides specific registers
to specify the aperture's base and size. This aperture can also be
changed dynamically in order to re-size the memory available for
DRM video playback. In case of the new aperture not overlapping
the previous one, the previous aperture has to be cleared before
setting up the new one. This means we do not "leak" any video data
to the NS world.

parameter using the 'SPD=<dispatcher>' option. The Tegra docs have

Support for NVIDIA's Tegra T210 SoCs

T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
at a given point in time.

This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
also adds support to boot secondary CPUs, enter/exit core power states for
all CPUs in the slow/fast clusters. The support to switch between clusters
is still not available in this patch and would be available later.
