This patch implements the handler to calculate the cluster and system power states for the Tegra210 SoC. The power states returned by this handler are used by the PSCI library to decide cache maintenance operations - cluster v cpu.

This patch fixes the logic used to calculate the end of NS memory aperture. The functions allows zero sized NS apertures as that is a valid requirement for some use cases. e.g. VPR resize. Change-Id: Ie966e0ea2f9c6888d21c38e734003704094b3720 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

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. Change-Id: I471167ef7747154440df5c1a5e015fbeb69d9043 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

Earlier, we were setting "System Suspend" as the power state for all system states. This caused incorrect system state during a cluster power down. This patch fixes this anomaly and sets the correct power state during a cluster/system power down.

utils.h is included in various header files for the defines in it. Some of the other header files only contain defines. This allows the header files to be shared between host and target builds for shared defines. Recently types.h has been included in utils.h as well as some function prototypes. Because of the inclusion of types.h conflicts exist building host tools abd these header files now. To solve this problem, move the defines to utils_def.h and have this included by utils.h and change header files to only include utils_def.h and not pick up the new types.h being introduced. Fixes ARM-software/tf-issues#461 Signed-off-by: Scott Branden <scott.branden@broadcom.com> Remove utils_def.h from utils.h This patch removes utils_def.h from utils.h as it is not required. And also makes a minor change to ensure Juno platform compiles. Change-Id: I10cf1fb51e44a8fa6dcec02980354eb9ecc9fa29

One assert depends on code that is conditionally compiled based on the DEBUG define. This patch modifies the conditional inclusion of such code so that it is based on the ENABLE_ASSERTIONS build option.

The CSS power management layer previously allowed to suspend system power domain level via both PSCI CPU_SUSPEND and PSCI SYSTEM_SUSPEND APIs. System suspend via PSCI CPU_SUSPEND was always problematic to support because of issues with targeting wakeup interrupts to suspended cores before the per-cpu GIC initialization is done. This is not the case for PSCI SYSTEM_SUSPEND API because all the other cores are expected to be offlined prior to issuing system suspend and PSCI CPU_ON explicit calls will be made to power them on. Hence the Juno platform used to downgrade the PSCI CPU_SUSPEND request for system power domain level to cluster level by overriding the default `plat_psci_pm_ops` exported by CSS layer. Given the direction the new CSS platforms are evolving, it is best to limit the system suspend only via PSCI SYSTEM_SUSPEND API for all CSS platforms. This patch makes changes to allow system suspend only via PSCI SYSTEM_SUSPEND API. The override of `plat_psci_ops` for Juno is removed.

This patch sanity checks the SMMU context created by the platform code. The first entry contains the size of the array; which the driver now verifies before moving on with the save. This patch also fixes an error in the calculation of the size of the context that gets copied to TZDRAM. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

Following steps are required to boot JUNO in AArch32 state: 1> BL1, in AArch64 state, loads BL2. 2> BL2, in AArch64 state, initializes DDR. Loads SP_MIN & BL33 (AArch32 executable)images. Calls RUN_IMAGE SMC to go back to BL1. 3> BL1 writes AArch32 executable opcodes, to load and branch at the entrypoint address of SP_MIN, at HI-VECTOR address and then request for warm reset in AArch32 state using RMR_EL3. This patch makes following changes to facilitate above steps: * Added assembly function to carry out step 3 above. * Added region in TZC that enables Secure access to the HI-VECTOR(0xFFFF0000) address space. * AArch32 image descriptor is used, in BL2, to load SP_MIN and BL33 AArch32 executable images. A new flag `JUNO_AARCH32_EL3_RUNTIME` is introduced that controls above changes. By default this flag is disabled. NOTE: BL1 and BL2 are not supported in AArch32 state for JUNO.

If there is a pending interrupt, it is possible for the AP to come out of the final WFI before SCP has a chance to act on it. Prevent this by disabling the GIC CPU interface before issuing a WFI. Previously, SCP would not wait on WFI before taking an action but would shut down the core or system regardless.

The build option `ENABLE_ASSERTIONS` should be used instead. That way both C and ASM assertions can be enabled or disabled together. All occurrences of `ASM_ASSERTION` in common code and ARM platforms have been replaced by `ENABLE_ASSERTIONS`. ASM_ASSERTION has been removed from the user guide.

ARM platforms have migrated to the translation tables library v2. However, for testing purposes, it can be useful to temporarily switch back to the old version. This patch introduces the option `ARM_XLAT_TABLES_LIB_V1`, that switches to v1 of the library when is set to 1. By default, it is 0, so that ARM platforms use the new version unless specifically stated. Updated User Guide.

This patch adds support for fake system suspend (SC7). This is a debug mode, to ensure that a different code path is executed for cases like pre-silicon development, where a full-fledged SC7 is not possible in early stages. This particular patch ensures that, if fake system suspend is enabled (denoted by tegra_fake_system_suspend variable having a non-zero value), instead of calling WFI, a request for a warm reset is made for starting the SC7 exit procedure. This ensures that the code path of kernel->ATF and back to kernel is executed without depending on other components involved in SC7 code path. Additionally, this patch also adds support for SMC call from kernel, enabling fake system suspend mode.

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. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

GCC version 4.8 (and presumably earlier) warn when non-standard types are used for bitfield definitions when -pedantic is enabled. This prevents TF from being built with such toolchains, since -Werror -pedantic options are used. gcc-4.9 removed this warning; -pedantic is intended to cause gcc to emit a warning in all cases required by the standard, but the standard does not require a warning in this case.

This patch makes the default implementation of plat_core_pos_by_mpidr() as weakly linked, so that platforms can override it with their own. Tegra186, for one, does not have CPU IDs 2 and 3, so it has its own implementation of plat_core_pos_by_mpidr().
