Varun Wadekar f5f64e4dbc Tegra: memctrl: check GPU reset state from common place
This patch moves the GPU reset state check, during VideoMem resize, to the
common SiP handler, to reduce code duplication.

Varun Wadekar 9d42d23a2c Tegra: memctrl_v2: zero out NS Video memory carveout region
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.

Varun Wadekar 0c2276e35f Tegra: memctrl_v1: disable AHB redirection after cold boot
During boot, USB3 and flash media (SDMMC/SATA) devices need access to
IRAM. Because these clients connect to the MC and do not have a direct
path to the IRAM, the MC implements AHB redirection during boot to allow
path to IRAM. In this mode, accesses to a programmed memory address aperture
are directed to the AHB bus, allowing access to the IRAM. The AHB aperture
is defined by the IRAM_BASE_LO and IRAM_BASE_HI registers, which are
initialized to disable this aperture. Once bootup is complete, we must
program IRAM base/top, thus disabling access to IRAM.

This patch provides functionality to disable this access. The tegra port
calls this new function before jumping to the non-secure world during
cold boot.

Mustafa Yigit Bilgen d81938ab3a Tegra: memctrl_v2: no SID override for AON
Remove stream ID overrides for AON. AON drives its own stream ID when
accesing IOVA memory. However, it needs to use a physical stream ID when
accesing GSC memory. Overriding stream ids prevents AON from accessing
GSC memory, so remove them to allow AON to access GSCs.

Varun Wadekar e64ce3abb3 Tegra186: re-configure MSS' client settings
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.
