This patch saves the TZSRAM context and takes the SoC into System Suspend from the "_wfi" handler. This helps us save the entire CPU context from the TZSRAM, before entering System Suspend. In the previous implementation we missed saving some part of the state machine context leading to an assert on System Suspend exit.

This patch disables SMMU hardware before suspending the SE block, for the context save operation to complete. The NS word will re-enable SMMU when we exit System Suspend. Change-Id: I4d5cd982ea6780db5c38b124550d847e3928c60d Signed-off-by: Samuel Payne <spayne@nvidia.com>

This patch removes the logic to set the bit that enables atomic context save/restore when we enter System suspend. The bootrom enables this bit during cold boot and exit from System Suspend, so we can remove this setting from the driver.

This patch enables L2 error correction and parity protection for Tegra210 on boot and exit from suspend. The previous bootloader sets the boot parameter, indicating ECC reporting, only for B01 SKUs. Change-Id: I6927884d375a64c69e2f1e9aed85f95c5e3cb17c Signed-off-by: Sam Payne <spayne@nvidia.com>

This patch memmaps all the IRAM memory banks during boot. The BPMP firmware might place the channels in any of the IRAMs, so it is better to map all the banks to avoid surprises. Change-Id: Ia009a65d227ee50fbb23e511ce509daf41b877ee Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

DRBG must be initialized to guarantee SRK has a random value during suspend. This patch add a sequence to generate an SRK on boot and during resume for SE1 and SE2. This SRK value is not saved to PMC scratch, and should be overwitten during atomic suspend. Change-Id: Id5e2dc74a1b462dd6addaec1709fec46083a6e1c Signed-off-by: Sam Payne <spayne@nvidia.com>

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.

This patch adds the implementation of the SE atomic context save sequence. The atomic context-save consistently saves to the TZRAM carveout; thus there is no need to declare context save buffer or map MMU region in TZRAM for context save. The atomic context-save routine is responsible to validate the context-save progress counter, where CTX_SAVE_CNT=133(SE1)/646(SE2), and the SE error status to ensure the context save procedure complete successfully.

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.

Commit fdb1964c ("xlat: Introduce MAP_REGION2() macro") added a granularity field to mmap_region_t. Tegra platforms were using the v2 xlat_tables implementation in common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c where arrays are being defined. This caused the next physical address to be read as granularity, causing EINVAL error and triggering an assert. Consistently use xlat_tables_v2.h header to avoid this. Fixes ARM-software/tf-issues#548. Signed-off-by: Andreas Färber <afaerber@suse.de>

There are some exceptions to this change in order to retain header groupings and where there are headers within #if statements.

The power states returned by this handler are used by the PSCI library to decide cache maintenance operations - cluster v cpu.

The linux kernel v3.10 does not use System Suspend function ID, whereas v4.4 uses it. This means affinity levels 0/1 will have different state id values during System Suspend entry. This patch updates the assert criteria to check both the state id values.

Tegra chips support multiple FIQ interrupt sources. These interrupts are enabled in the GICD/GICC interfaces by the tegra_gic driver. A new FIQ handler would be added in a subsequent change which can be registered by the platform code. This patch adds the GIC programming as part of the tegra_gic_setup() which now takes an array of all the FIQ interrupts to be enabled for the platform. The Tegra132 and Tegra210 platforms right now do not register for any FIQ interrupts themselves, but will definitely use this support in the future.

The BL2 fills in the UART controller ID to be used as the normal as well as the crash console on Tegra platforms. The controller ID to UART controller base address mapping is handled by each Tegra SoC the base addresses might change across Tegra chips. This patch adds the handler to parse the platform params to get the UART ID for the per-soc handlers.

This patch moves the definition for `plat_get_syscnt_freq()` from arm_bl31_setup.c to arm_common.c. This could be useful in case a delay timer needs to be installed based on the generic timer in other BLs. This patch also modifies the return type for this function from `uint64_t` to `unsigned long long` within ARM and other platform files. Change-Id: Iccdfa811948e660d4fdcaae60ad1d700e4eda80d

This patch programs the CPUECTLR_EL1 and L2ECTLR_EL1 registers, so that the core waits for 512 generic timer CNTVALUEB ticks before entering retention state, after executing a WFI instruction.

The Memory Select Switch Controller routes any CPU transactions to the appropriate slave depending on the transaction address. During system suspend, it loses all config settings and hence the CPU has to restore them during resume. This patch restores the controller's settings for enabling WRAP to INCR burst type conversions on the master ports, for any incoming requests from the AXI slave ports. Tested by performing multiple system suspend cycles. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>
