2018-12-10SPM: Deprecate the current implementationAntonio Nino Diaz
The current SPM is a prototype that only supports one secure partition in EL0. The objective of SPM is to have multiple partitions. The current MM interface isn't adequate for this, so it is needed to modify heavily the code to add proper support for it. However, there are platforms which are already using this (like SGI) and removing the code would break it. For this reason, the current SPM code has been duplicated in order to temporarily preserve compatibility. All new improvements/changes to SPM will be done in the non-deprecated copy, that may change without notice. The new build option SPM_DEPRECATED has been introduced to select the SPM implementation. It defaults to 1, that selects the deprecated SPM. Change-Id: Ic9f80b53b450e97b4d3f47e4ef4a138ee8d87443 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
2018-12-06drivers/console: Reimplement MUTLI_CONSOLE_API framework in CJulius Werner
Now that we have switched to using the stack in MULTI_CONSOLE_API framework functions and have factored all code involved in crash reporting out into a separate file, there's really no reason to keep the main framework code in assembly anymore. This patch rewrites it in C which allows us to have a single implementation across aarch32/64 and should be much easier to maintain going forward.

2018-12-06drivers/console: Link console framework code by defaultJulius Werner
This patch makes the build system link the console framework code by default, like it already does with other common libraries (e.g. cache helpers). This should not make a difference in practice since TF is linked with --gc-sections, so the linker will garbage collect all functions and data that are not referenced by any other code. Thus, if a platform doesn't want to include console code for size reasons and doesn't make any references to console functions, the code will not be included in the final binary. To avoid compatibility issues with older platform ports, only make this change for the MULTI_CONSOLE_API.

2018-10-19Makefile: Fix verbose builds on WindowsAntonio Nino Diaz
Commit <ee1ba6d4ddf1> ("Makefile: Support totally quiet output with -s") broke verbose (V=1) builds on Windows. This patch fixes it by adding helpers to silence echo prints in a OS-dependent way.

2018-10-08Makefile: Support totally quiet output with -sAndre Przywara
"-s" is a command line option to the make tool, to suppress normal output, something to the effect of prepending every line with '@' in the Makefile. However with our V={0|1} support, we now print the shortened command line output in any case (even with V=1, in addition to the long line!). Normally -s helps to not miss non-fatal warnings, which tend to scroll out of the window easily. Introduce a new Makefile variable ECHO, to control the shortened output. We only set it in the (current default) V=0 case, and replace every occurence of "@echo" with that variable. When the user specifies "-s", we set ECHO to some magic string which changes the output line into a comment, so the output is suppressed. Beside suppressing every output for "-s", we also avoid the redundant short output when compiling with V=1. This changes the output to: ========== $ make -s PLAT=.... bl31 Built build/.../release/bl31.bin ========== $ make PLAT=.... bl31 ... CC lib/libc/strncmp.c CC lib/libc/strnlen.c ... ========== $ make V=1 PLAT=.... bl31 ... gcc -DDEBUG=0 .... -o build/.../release/libc/strncmp.o gcc -DDEBUG=0 .... -o build/.../release/libc/strnlen.o ... ========== Signed-off-by: Andre Przywara <andre.przywara@arm.com>

2018-08-30backtrace: Introduce backtrace functionDouglas Raillard
This function diplays the backtrace, the current EL and security state to allow a post-processing tool to choose the right binary to interpret the dump. The output can be fed to GNU addr2line to resolve function names given an ELF binary compiled with debug information. The "-i" flag is recommended to improve display in case of inlined functions. The *.dump files generated during the build process can also be used. The function works in AArch64 and AArch32. In AArch32 it only works in A32 mode (without T32 interworking), which is enforced in the Makefile. Sample output of a backtrace at EL3: BACKTRACE: START: function_name 0: EL3: 0x798 1: EL3: 0x538 2: EL3: 0x550 3: EL3: 0x55c 4: EL3: 0x568 5: EL3: 0x5a8 6: EL3: 0xf4 BACKTRACE: END: function_name In order to enable it the new option ENABLE_BACKTRACE must be set to 1. This option is set to 1 by default only in AArch64 debug builds. As usual, it can be overridden by the platform makefile and in the build command line.

2018-08-30Allow manually setting the AArch32 instruction setAntonio Nino Diaz
At the moment the AArch32 instruction set isn't specified in the command line, which means that the compiler is free to choose the one it sees fit. This decision may change between compiler versions, so it is better to specify it manually. The build option AARCH32_INSTRUCTION_SET has been introduced for this reason. This option can be set to T32 or A32 to pass the correct flags to the compiler. The current behaviour is to default to T32 due to it's smaller size.

2018-08-20AArch64: Enable MPAM for lower ELsJeenu Viswambharan
Memory Partitioning And Monitoring is an Armv8.4 feature that enables various memory system components and resources to define partitions. Software running at various ELs can then assign themselves to the desired partition to control their performance aspects. With this patch, when ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows lower ELs to access their own MPAM registers without trapping to EL3. This patch however doesn't make use of partitioning in EL3; platform initialisation code should configure and use partitions in EL3 if required.

2018-07-03AArch32: Force compiler to align memory accessesSandrine Bailleux
Alignment fault checking is always enabled in TF (by setting the SCTLR.A bit). Thus, all instructions that load or store one or more registers have an alignment check that the address being accessed is aligned to the size of the data element(s) being accessed. If this check fails it causes an Alignment fault, which is taken as a Data Abort exception. The compiler needs to be aware that it must not emit load and store instructions resulting in unaligned accesses. It already is for AArch64 builds (see commit fa1d37122c "Add -mstrict-align to the gcc options"), this patch does the same for AArch32 builds.

2018-05-04RAS: Add fault injection supportJeenu Viswambharan
The ARMv8.4 RAS extensions introduce architectural support for software to inject faults into the system in order to test fault-handling software. This patch introduces the build option FAULT_HANDLING_SUPPORT to allow for lower ELs to use registers in the Standard Error Record to inject fault. The build option RAS_EXTENSIONS must also be enabled along with fault injection. This feature is intended for testing purposes only, and is advisable to keep disabled for production images.

2018-05-04AArch64: Introduce RAS handlingJeenu Viswambharan
RAS extensions are mandatory for ARMv8.2 CPUs, but are also optional extensions to base ARMv8.0 architecture. This patch adds build system support to enable RAS features in ARM Trusted Firmware. A boolean build option RAS_EXTENSION is introduced for this. With RAS_EXTENSION, an Exception Synchronization Barrier (ESB) is inserted at all EL3 vector entry and exit. ESBs will synchronize pending external aborts before entering EL3, and therefore will contain and attribute errors to lower EL execution. Any errors thus synchronized are detected via. DISR_EL1 register. When RAS_EXTENSION is set to 1, HANDLE_EL3_EA_FIRST must also be set to 1.

2018-05-04AArch64: Introduce External Abort handlingJeenu Viswambharan
At present, any External Abort routed to EL3 is reported as an unhandled exception and cause a panic. This patch enables ARM Trusted Firmware to handle External Aborts routed to EL3. With this patch, when an External Abort is received at EL3, its handling is delegated to plat_ea_handler() function. Platforms can provide their own implementation of this function. This patch adds a weak definition of the said function that prints out a message and just panics. In order to support handling External Aborts at EL3, the build option HANDLE_EA_EL3_FIRST must be set to 1. Before this patch, HANDLE_EA_EL3_FIRST wasn't passed down to compilation; this patch fixes that too.

Due to differences in the bitfields of the SMC IDs, it is not possible to support SMCCC 1.X and 2.0 at the same time. The behaviour of `SMCCC_MAJOR_VERSION` has changed. Now, it is a build option that specifies the major version of the SMCCC that the Trusted Firmware supports. The only two allowed values are 1 and 2, and it defaults to 1. The value of `SMCCC_MINOR_VERSION` is derived from it. Note: Support for SMCCC v2.0 is an experimental feature to enable prototyping of secure partition specifications.

2018-03-01Improve MULTI_CONSOLE_API deprecation warningsDan Handley
For platforms that have not migrated to MULTI_CONSOLE_API == 1, there are a lot of confusing deprecated declaration warnings relating to use of console_init() and console_uninit(). Some of these relate to use by the generic code, not the platform code. These functions are not really deprecated but *removed* when MULTI_CONSOLE_API == 1. This patch consolidates these warnings into a single preprocessor warning. The __deprecated attribute is removed from the console_init() and console_uninit() declarations. For preprocessor warnings like this to not cause fatal build errors, this patch adds -Wno-error=cpp to the build flags when ERROR_DEPRECATED == 0. This option (and -Wno-error=deprecated-declarations) is now added to CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the assembler as well as the compiler. This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED build flags by defaulting MULTI_CONSOLE_API to 0 instead of ERROR_DEPRECATED. This allows platforms that have not migrated to MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful build error. Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since the AArch32 console implementation does not support MULTI_CONSOLE_API == 1.
