This patch organizes the memory and mmio maps linearly, to make the mmap_add_region process faster. The microsecond timer has been moved to individual platforms instead of making it a common step, as it further speeds up the memory map creation process.

This patch enables the watchdog timer's interrupt as an FIQ interrupt to the CPU. The interrupt generated by the watchdog is connected to the flow controller for power management reasons, and needs to be routed to the GICD for it to reach the CPU.

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?

This patch removes the error print displayed when bpmp init fails. On platforms that do not load the bpmp firmware, this print is seen on every cluster idle and powerdown request, cluttering the logs.

This patch adds support to handle secure PPIs for Tegra watchdog timers. This functionality is currently protected by the ENABLE_WDT_LEGACY_FIQ_HANDLING configuration variable and is only enabled for Tegra210 platforms, for now.

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.

Whenever the VPR memory is resized, the GPU is put into reset first and then the new VPR parameters are programmed to the memory controller block. There exists a scenario, where the GPU might be out before we program the new VPR parameters. This means, the GPU would still be using older settings and leak secrets. This patch puts the GPU back into reset, if it is out of reset after resizing VPR, to mitigate this hole.

The GICD registers are 32-bits wide whereas the crash handler was reading them as 64-bit ones. This patch fixes the code to read the GICD registers, 32-bits at a time, from the paltform's crash handler.

Current implementation of i.MX8QX power management related features does NOT optimize power number, all system resources like CCI, DDR, and A cluster etc. are kept in STBY mode (powered ON) when system suspend or CPU hotplug. To lower the power number, OFF mode should be adopted for those system resources whenever they can be OFF, A cluster will be OFF if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF if system suspend, IRQ steer can be OFF if the wakeup source is belonged to system controller partition, so wakeup source runtime check is used to determine if IRQ steer can be OFF before system suspend. If resources are powered off for suspend, they should be restored properly after system resume. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

After the removal of deprecated interfaces in TF 2.0 the migration to the new GIC driver interfaces was done incorrectly in rk3328 and rk3368: 2d6f1f01 ("rockchip: Migrate to new interfaces"). In the GICv2 driver it is mandated that all interrupts are Group 0 interrupts. This patch simply moves all Group 1 interrupts to Group 0.

The PLAT_XLAT_TABLES_DYNAMIC build option, defined in platform_def.h in Arm platforms, is checked by several headers, affecting their behaviour. To avoid issues around the include ordering of the headers, the definition should be moved to the platform's makefile.

This patch adds a platform setup handler that gets called after the MMU is enabled. Platforms wanting to make use of this handler should declare 'plat_late_platform_setup' handler in their platform files, to override the default weakly defined handler.

There are Tegra platforms which have limited UART ports and so all the components have to share the console. The SPE helps out by collecting all the logs in such cases and prints them on the shared UART port. This patch adds a driver to communicate with the SPE driver, which in turn provides the console.

This patch adds support to save the system suspend entry and exit markers to TZDRAM to help the trampoline code decide if the current warmboot is actually an exit from System Suspend. The Tegra186 platform handler sets the system suspend entry marker before entering SC7 state and the trampoline flips the state back to system resume, on exiting SC7.
