      Tegra210: bpmp: power management interface · dd1a71f1
      Varun Wadekar authored 
      

This patch adds the driver to communicate with the BPMP processor
for power management use cases. BPMP controls the entry into cluster
and system power states. The Tegra210 platform port queries the BPMP
to calculate the target state for the cluster. In case BPMP does not
allow CCx entry, the core enters a power down state.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

      Tegra: memctrl_v2: zero out NS Video memory carveout region · 9d42d23a
      Varun Wadekar authored 
      

The video memory carveout has to be re-sized depending on the Video
content. This requires the NS world to send us new base/size values.
Before setting up the new region, we must zero out the previous memory
region, so that the video frames are not leaked to the outside world.

This patch adds the logic to zero out the previous memory carveout
region.

      Tegra: memctrl_v1: enable 'xlat_table_v2' library · c05a2197
      Varun Wadekar authored 
      

This patch enables the 'xlat_table_v2' library for the Tegra Memory
Controller driver. This library allows us to dynamically map/unmap
memory regions, with MMU enabled.

The Memory Controller driver maps/unmaps non-overlapping Video Memory
region, to clean it of any secure contents, before it resizes the
region.
