2019-10-03delay: timeout detection supportLionel Debieve
Introduce timeout_init_us/timeout_elapsed() delay tracking with CNTPCT. timeout_init_us(some_timeout_us); returns a reference to detect timeout for the provided microsecond delay value from current time. timeout_elapsed(reference) return true/false whether the reference timeout is elapsed. Cherry picked from OP-TEE implementation [1]. [1] commit 33d30a74502b ("core: timeout detection support") Minor: - Remove stm32mp platform duplicated implementation. - Add new include in marvell ble.mk Signed-off-by: Etienne Carriere <etienne.carriere@linaro.org> Signed-off-by: Lionel Debieve <lionel.debieve@st.com> Change-Id: Iaef6d43c11a2e6992fb48efdc674a0552755ad9c
2019-09-23stm32mp1: add authentication support for stm32imageLionel Debieve
This commit adds authentication binary support for STM32MP1. It prints the bootrom authentication result if signed image is used and authenticates the next loaded STM32 images. It also enables the dynamic translation table support (PLAT_XLAT_TABLES_DYNAMIC) to use bootrom services.

Among the variants of STM32MP, the STM32MP151 is a single Cortex-A7 chip. A function is added to check the part number of the SoC.

2019-09-02stm32mp1: add watchdog supportYann Gautier
Introduce driver for STM32 IWDG peripheral (Independent Watchdog). It is configured according to device tree content and should be enabled from there. The watchdog is not started by default. It can be started after an HW reset if the dedicated OTP is fused. The watchdog also needs to be frozen if a debugger is attached. This is done by configuring the correct bits in DBGMCU. This configuration is allowed by checking BSEC properties. An increase of BL2 size is also required when adding this new code.

2019-08-01Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__Julius Werner
NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__. All common C compilers predefine a macro called __ASSEMBLER__ when preprocessing a .S file. There is no reason for TF-A to define it's own __ASSEMBLY__ macro for this purpose instead. To unify code with the export headers (which use __ASSEMBLER__ to avoid one extra dependency), let's deprecate __ASSEMBLY__ and switch the code base over to the predefined standard.

2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("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.

MULTI_CONSOLE_API fixes and cleanups
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.
