This patch saves the TZDRAM base and size values to secure scratch registers, for the WB0. The WB0 reads these values and uses them to verify integrity of the TZDRAM aperture.

This patch removes this macro and its usage as it is used only within the Tegra186 files and all derived platforms keep the macro enabled. Change-Id: Ib831b3c002ba4dedc3d5fafbb7d321daa28fa9ea Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

As per the latest recommendations from the hardware team, write access needs to be disabled for APE, BPMP, NvDec and SCE clients. This patch disables stream id register writes for these MC clients to implement those recommendations.

The Tegra memctrl driver sets up the TZDRAM fence during boot and system suspend exit. This patch provides individual platforms with handlers to perform custom steps during TZDRAM setup. Change-Id: Iee094d6ca189c6dd24f1147003c33c99ff3a953b Signed-off-by: Steven Kao <skao@nvidia.com>

This patch renames all the secure scratch registers to reflect their usage. This is a list of all the macros being renamed: - SECURE_SCRATCH_RSV1_* -> SCRATCH_RESET_VECTOR_* - SECURE_SCRATCH_RSV6 -> SCRATCH_SECURE_BOOTP_FCFG - SECURE_SCRATCH_RSV11_* -> SCRATCH_SMMU_TABLE_ADDR_* - SECURE_SCRATCH_RSV53_* -> SCRATCH_BOOT_PARAMS_ADDR_* - SECURE_SCRATCH_RSV55_* -> SCRATCH_TZDRAM_ADDR_* NOTE: Future SoCs will have to define these macros to keep the drivers functioning.

The Tegra memctrl driver sets up the TZDRAM fence during boot and system suspend exit. This patch provides individual platforms with handlers to perform platform specific steps, e.g. enable encryption, save base/size to secure scratch registers.

Introduce platform handlers to program the MSS settings. This allows the current driver to scale to future chips. Change-Id: I40a27648a1a3c73b1ce38dafddc1babb6f0b0d9b Signed-off-by: Puneet Saxena <puneets@nvidia.com> Signed-off-by: Krishna Reddy <vdumpa@nvidia.com>

MISRA Rule 10.3, the value of an expression shall not be assigned to an object with a narrower essential type or of a different essential type category. The essential type of a enum member is anonymous enum, the enum member should be casted to the right type when using it. Both UL and ULL suffix equal to uint64_t constant in compiler aarch64-linux-gnu-gcc, to avoid confusing, only keep U and ULL suffix in platform code. So in some case, cast a constant to uint32_t is necessary. Change-Id: I1aae8cba81ef47481736e7f95f53570de7013187 Signed-off-by: Anthony Zhou <anzhou@nvidia.com>

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 patch empowers the platforms to provide the settings (e.g. stream ID, security setting, transaction overrides) required by the Memory Controller driver. This allows the platforms to program the Memory Controller as per their needs and makes the driver scalable.
