On Juno AArch32, the L2 cache may contain garbage after the warm reset from AArch64 to AArch32. This is all fine until the MMU is configured and the data caches enabled. To avoid fetching stale data from the L2 unified cache, invalidate it before the warm reset to AArch32 state.

Before BL2 loads the SCP ram firmware, `SCP_BOOT_CFG_ADDR` specifies the primary core. After the SCP ram firmware has started executing, `SCP_BOOT_CFG_ADDR` is modified. This is not normally an issue but the Juno AArch32 boot flow is a special case. BL1 does a warm reset into AArch32 and the core jumps to the `sp_min` entrypoint. This is effectively a `RESET_TO_SP_MIN` configuration. `sp_min` has to be able to determine the primary core and hence we need to restore `SCP_BOOT_CFG_ADDR` to the cold boot value before `sp_min` runs. This magically worked when booting on A53 because the core index was zero and it just so happened to match with the new value in `SCP_BOOT_CFG_ADDR`.

The header tbbr_oid.h contains OIDs obtained by ARM Ltd. so there is no good reason to use platform_oid.h Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Platforms aligned with TBBR are supposed to use their own OIDs, but defining the same macros with different OIDs does not provide any value (at least technically). For easier use of TBBR, this commit allows platforms to reuse the OIDs obtained by ARM Ltd. This will be useful for non-ARM vendors that do not need their own extension fields in their certificate files. The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by defining USE_TBBR_DEFS as 1. USE_TBBR_DEFS is 0 by default to keep the backward compatibility. For clarification, I inserted a blank line between headers from the include/ directory (#include <...>) and ones from a local directory (#include "..." ).

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.

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.

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.

ARM erratum 855873 applies to all Cortex-A53 CPUs. The recommended workaround is to promote "data cache clean" instructions to "data cache clean and invalidate" instructions. For core revisions of r0p3 and later this can be done by setting a bit in the CPUACTLR_EL1 register, so that hardware takes care of the promotion. As CPUACTLR_EL1 is both IMPLEMENTATION DEFINED and can be trapped to EL3, we set the bit in firmware. Also we dump this register upon crashing to provide more debug information. Enable the workaround for the Juno boards. Change-Id: I3840114291958a406574ab6c49b01a9d9847fec8 Signed-off-by: Andre Przywara <andre.przywara@arm.com>

TLBI instructions for EL3 won't have the desired effect under specific circumstances in Cortex-A57 r0p0. The workaround is to execute DSB and TLBI twice each time. Even though this errata is only needed in r0p0, the current errata framework is not prepared to apply run-time workarounds. The current one is always applied if compiled in, regardless of the CPU or its revision. This errata has been enabled for Juno. The `DSB` instruction used when initializing the translation tables has been changed to `DSB ISH` as an optimization and to be consistent with the barriers used for the workaround.

One nasty part of ATF is some of boolean macros are always defined as 1 or 0, and the rest of them are only defined under certain conditions. For the former group, "#if FOO" or "#if !FOO" must be used because "#ifdef FOO" is always true. (Options passed by $(call add_define,) are the cases.) For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because checking the value of an undefined macro is strange. Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like follows: $(eval IMAGE := IMAGE_BL$(call uppercase,$(3))) $(OBJ): $(2) @echo " CC $$<" $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@ This means, IMAGE_BL* is defined when building the corresponding image, but *undefined* for the other images. So, IMAGE_BL* belongs to the latter group where we should use #ifdef or #ifndef. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

The capabilities exposed by the PSCI generic layer depends on the hooks populated by the platform in `plat_arm_psci_pm_ops`. Currently ARM Standard platforms statically define this structure. However, some platforms may want to modify the hooks at runtime before registering them with the generic layer. This patch introduces a new ARM platform layer API `plat_arm_psci_override_pm_ops` which allows the platform to probe the power controller and modify `plat_arm_psci_pm_ops` if required. Consequently, 'plat_arm_psci_pm_ops' is no longer qualified as `const` on ARM Standard platforms. Change-Id: I7dbb44b7bd36c20ec14ded5ee45a96816ca2ab9d Signed-off-by: Soby Mathew <soby.mathew@arm.com>

There are many instances in ARM Trusted Firmware where control is transferred to functions from which return isn't expected. Such jumps are made using 'bl' instruction to provide the callee with the location from which it was jumped to. Additionally, debuggers infer the caller by examining where 'lr' register points to. If a 'bl' of the nature described above falls at the end of an assembly function, 'lr' will be left pointing to a location outside of the function range. This misleads the debugger back trace. This patch defines a 'no_ret' macro to be used when jumping to functions from which return isn't expected. The macro ensures to use 'bl' instruction for the jump, and also, for debug builds, places a 'nop' instruction immediately thereafter (unless instructed otherwise) so as to leave 'lr' pointing within the function range.

Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to `ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines related to the translation tables but to the image size as well. The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and `PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h. This way, ARM platforms no longer have to set their own values if `ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values otherwise. The common sizes have been set to the highest values used for any of the current build configurations. This is needed because in some build configurations some images are running out of space. This way there is a common set of values known to work for all of them and it can be optimized for each particular platform if needed. The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been increased. This is needed because when memory optimisations are disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` are higher. If in this situation the code is compiled in debug mode and with "-O0", the code won't fit. Change-Id: I70a3d8d3a0b0cad1d6b602c01a7ea334776e718e

This patch reworks type usage in generic code, drivers and ARM platform files to make it more portable. The major changes done with respect to type usage are as listed below: * Use uintptr_t for storing address instead of uint64_t or unsigned long. * Review usage of unsigned long as it can no longer be assumed to be 64 bit. * Use u_register_t for register values whose width varies depending on whether AArch64 or AArch32. * Use generic C types where-ever possible. In addition to the above changes, this patch also modifies format specifiers in print invocations so that they are AArch64/AArch32 agnostic. Only files related to upcoming feature development have been reworked. Change-Id: I9f8c78347c5a52ba7027ff389791f1dad63ee5f8

This patch enables optional PSCI functions `PSCI_STAT_COUNT` and `PSCI_STAT_RESIDENCY` for ARM standard platforms. The optional platform API 'translate_power_state_by_mpidr()' is implemented for the Juno platform. 'validate_power_state()' on Juno downgrades PSCI CPU_SUSPEND requests for the system power level to the cluster power level. Hence, it is not suitable for validating the 'power_state' parameter passed in a PSCI_STAT_COUNT/RESIDENCY call. Change-Id: I9548322676fa468d22912392f2325c2a9f96e4d2

`board_arm_def.h` contains multiple definitions of `PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` that are optimised for memory usage depending upon the chosen build configuration. To ease maintenance of these constants, this patch replaces their multiple definitions with a single set of definitions that will work on all ARM platforms. Platforms can override the defaults with optimal values by enabling the `ARM_BOARD_OPTIMISE_MMAP` build option. An example has been provided in the Juno ADP port. Additionally, `PLAT_ARM_MMAP_ENTRIES` is increased by one to accomodate future ARM platforms. Change-Id: I5ba6490fdd1e118cc9cc2d988ad7e9c38492b6f0

The common topology description helper funtions and macros for ARM Standard platforms assumed a dual cluster system. This is not flexible enough to scale to multi cluster platforms. This patch does the following changes for more flexibility in defining topology: 1. The `plat_get_power_domain_tree_desc()` definition is moved from `arm_topology.c` to platform specific files, that is `fvp_topology.c` and `juno_topology.c`. Similarly the common definition of the porting macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform specific `platform_def.h` header. 2. The ARM common layer porting macros which were dual cluster specific are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced which must be defined by each ARM standard platform. 3. A new mandatory ARM common layer porting API `plat_arm_get_cluster_core_count()` is introduced to enable the common implementation of `arm_check_mpidr()` to validate MPIDR. 4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been introduced which allows the user to specify the cluster count to be used to build the topology tree within Trusted Firmare. This enables Trusted Firmware to be built for multi cluster FVP models. Change-Id: Ie7a2e38e5661fe2fdb2c8fdf5641d2b2614c2b6b

ARM Trusted Firmware supports 2 different interconnect peripheral drivers: CCI and CCN. ARM platforms are implemented using either of the interconnect peripherals. This patch adds a layer of abstraction to help ARM platform ports to choose the right interconnect driver and corresponding platform support. This is as described below: 1. A set of ARM common functions have been implemented to initialise an interconnect and for entering/exiting a cluster from coherency. These functions are prefixed as "plat_arm_interconnect_". Weak definitions of these functions have been provided for each type of driver. 2.`plat_print_interconnect_regs` macro used for printing CCI registers is moved from a common arm_macros.S to cci_macros.S. 3. The `ARM_CONFIG_HAS_CCI` flag used in `arm_config_flags` structure is renamed to `ARM_CONFIG_HAS_INTERCONNECT`. Change-Id: I02f31184fbf79b784175892d5ce1161b65a0066c

Prior to this patch, it was assumed that on all ARM platforms the bare minimal security setup required is to program TrustZone protection. This would always be done by programming the TZC-400 which was assumed to be present in all ARM platforms. The weak definition of platform_arm_security_setup() in plat/arm/common/arm_security.c reflected these assumptions. In reality, each ARM platform either decides at runtime whether TrustZone protection needs to be programmed (e.g. FVPs) or performs some security setup in addition to programming TrustZone protection (e.g. NIC setup on Juno). As a result, the weak definition of plat_arm_security_setup() is always overridden. When a platform needs to program TrustZone protection and implements the TZC-400 peripheral, it uses the arm_tzc_setup() function to do so. It is also possible to program TrustZone protection through other peripherals that include a TrustZone controller e.g. DMC-500. The programmer's interface is slightly different across these various peripherals. In order to satisfy the above requirements, this patch makes the following changes to the way security setup is done on ARM platforms. 1. arm_security.c retains the definition of arm_tzc_setup() and has been renamed to arm_tzc400.c. This is to reflect the reliance on the TZC-400 peripheral to perform TrustZone programming. The new file is not automatically included in all platform ports through arm_common.mk. Each platform must include it explicitly in a platform specific makefile if needed. This approach enables introduction of similar library code to program TrustZone protection using a different peripheral. This code would be used by the subset of ARM platforms that implement this peripheral. 2. Due to #1 above, existing platforms which implements the TZC-400 have been updated to include the necessary files for both BL2, BL2U and BL31 images.

This patch moves the definition of some macros used only on ARM platforms from common headers to platform specific headers. It also forces all ARM standard platforms to have distinct definitions (even if they are usually the same). 1. `PLAT_ARM_TZC_BASE` and `PLAT_ARM_NSTIMER_FRAME_ID` have been moved from `css_def.h` to `platform_def.h`. 2. `MHU_BASE` used in CSS platforms is moved from common css_def.h to platform specific header `platform_def.h` on Juno and renamed as `PLAT_ARM_MHU_BASE`. 3. To cater for different sizes of BL images, new macros like `PLAT_ARM_MAX_BL31_SIZE` have been created for each BL image. All ARM platforms need to define them for each image.

The current FWU_SMC_UPDATE_DONE implementation incorrectly passes an unused framework cookie through to the 1st argument in the platform function `bl1_plat_fwu_done`. The intent is to allow the SMC caller to pass a cookie through to this function. This patch fixes FWU_SMC_UPDATE_DONE to pass x1 from the caller through to `bl1_plat_fwu_done`. The argument names are updated for clarity. Upstream platforms currently do not use this argument so no impact is expected. Change-Id: I107f4b51eb03e7394f66d9a534ffab1cbc09a9b2
