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.

2019-09-02stm32mp1: use a common function to check spinlock is availableYann Gautier
To use spinlocks, MMU should be enabled, as well as data cache. A common function is created (moved from clock file). It is then used whenever a spinlock has to be taken, in BSEC and clock drivers.

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.

2019-06-17stm32mp1: add general SYSCFG managementYann Gautier
The system configuration controller is mainly used to manage the compensation cell and other IOs and system related settings. The SYSCFG driver is in charge of configuring masters on the interconnect, IO compensation, low voltage boards, or pull-ups for boot pins. All other configurations should be handled in Linux drivers requiring it. Device tree files are also updated to manage vdd-supply regulator.

2019-06-17clk: stm32mp1: correctly handle Clock Spreading GeneratorYann Gautier

2019-06-17clk: stm32mp1: use defines for mask values in stm32mp1_clk_sel arrayYann Gautier
Rework the macro that eases the table definition: the src and msk fields are now using MASK and SHIFT defines of each source register. Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to _UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields. Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7 to reflect the size of the register field, even if there are only 3 possible clock sources. The mask value is also corrected for QSPI and FMC clock selection.

2019-02-14stm32mp1: update I2C and PMIC driversYann Gautier
Regulator configuration at boot takes more information from DT. I2C configuration from DT is done in I2C driver. I2C driver manages more transfer modes. The min voltage of buck1 should also be increased to 1.2V, else the platform does not boot. Heavily modifies stm32_i2c.c since many functions move inside the source file to remove redundant declarations.

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.
