This patch moves the 'drivers' and the 'lib' folders out of the 'common' folder. This way the 'common' folder shall contain only the platform support required for all Tegra platforms. Change-Id: I2f238572d0a078d60c6b458a559538dc8a4d1856 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

Now it is needed to use the full path of the common header files. Commit 09d40e0e ("Sanitise includes across codebase") provides more information. Change-Id: Ifedc79d9f664d208ba565f5736612a3edd94c647 Signed-off-by: Ambroise Vincent <ambroise.vincent@arm.com>

This patch adds support to enter System Suspend on Tegra210 platforms without the traditional BPMP firmware. The BPMP firmware will no longer be supported on Tegra210 platforms and its functionality will be divided across the CPU and sc7entry-fw. The sc7entry-fw takes care of performing the hardware sequence required to enter System Suspend (SC7 power state) from the COP. The CPU is required to load this firmware to the internal RAM of the COP and start the sequence. The CPU also make sure that the COP is off after cold boot and is only powered on when we want to start the actual System Suspend sequence. The previous bootloader loads the firmware to TZDRAM and passes its base and size as part of the boot parameters. The EL3 layer is supposed to sanitize the parameters before touching the firmware blob. To assist the warmboot code with the PMIC discovery, EL3 is also supposed to program PMC's scratch register #210, with appropriate values. Without these settings the warmboot code wont be able to get the device out of System Suspend. Change-Id: I5a7b868512dbfd6cfefd55acf3978a1fd7ebf1e2 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds helper functions to help platforms with cluster state entry and exit decisions. * tegra_fc_ccplex_pgexit_lock(): lock CPU power ungate * tegra_fc_ccplex_pgexit_unlock(): unlock CPU power ungate * tegra_fc_is_ccx_allowed(): CCx state entry allowed on this CPU?

On earlier Tegra platforms, e.g. Tegra210, the watchdog timer's FIQ interrupt is not direclty wired to the GICD. It goes to the flow controller instead, for power state management. But the flow controller can route the FIQ to the GICD, as a PPI, which can then get routed to the target CPU. This patch adds routines to enable/disable routing the legacy FIQ used by the watchdog timers, to the GICD.

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.

This fix modifies the order of system includes to meet the ARM TF coding standard. There are some exceptions to this change in order to retain header groupings and where there are headers within #if statements.

This patch fixes the delay loop used to wake up the BPMP during SC7 exit. The earlier loop would fail just when the timer was about to wrap-around (e.g. when TEGRA_TMRUS_BASE is 0xfffffffe, the target value becomes 0, which would cause the loop to exit before it's expiry).

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>
