This function can be used on several stm32mp devices, it is then moved in plat/st/common/stm32mp_common.c. Change-Id: I862debe39604410f71a9ddc28713026362e9ecda Signed-off-by:Yann Gautier <yann.gautier@st.com>

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. Change-Id: I94baed0114a2061ad71bd5287a91bf7f1c6821f6 Signed-off-by: -

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. If it corresponds to STM32MP151A or STM32MP151C, then the chip has a single Cortex-A7. Change-Id: Icac2015c5d03ce0bcb8e99bbaf1ec8ada34be49c Signed-off-by:

On STMicroelectronics boards, the board information is stored in OTP. This OTP is described in device tree, in BSEC board_id node. Change-Id: Ieccbdcb048343680faac8dc577b75c67ac106f5b Signed-off-by:

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. Change-Id: Ide7535d717885ce2f9c387cf17afd8b5607f3e7f Signed-off-by:

Do not export function dt_get_stdout_node_offset() that is used only inside stm32mp_dt.c source file. Change-Id: I9dd3dbfab21d42ed81c68723e71fe5a7586dce93 Signed-off-by: -

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.

GPIOx clocks are specific to each STM32MP platforms. This change moves function stm32_get_gpio_bank_clock() from stm32mp common source files to platform private stm32mp1_private.c source file. Change-Id: I9616c0d3fe4d10af715d6f2d1550c13ab62c829a Signed-off-by:

Support booting OP-TEE as BL32 boot stage and secure runtime service. OP-TEE executes in internal RAM and uses a secure DDR area to store the pager pagestore. Memory mapping and TZC are configured accordingly prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where a header file describes the effective boot images. This change post processes header file content to get OP-TEE load addresses and set OP-TEE boot arguments. Change-Id: I02ef8b915e4be3e95b27029357d799d70e01cd44 Signed-off-by:

The change of the structure highlighted the fact that all fields are not correctly initialized with zeroes. Replace the other memset in the function with zeromem, as it is faster. Change-Id: I27f45a64e34637f79fa519f486bf5936721ef396 Signed-off-by:

PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree. Platform asserts the value read from the DT are the SoC addresses. Change-Id: I43f0890b51918a30c87ac067d3780ab27a0f59de Signed-off-by:

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. This change is inspired by the OP-TEE OS timeout resources [1].

Include all RCC, clocks and reset headers from stm32mp1_def.h which if exported to the firmware through platform_def.h. The same dependency removal is done in common code as well. Some useless includes are also removed in stm32_sdmmc2 driver. Change-Id: I731ea5775c3fdb7f7b0c388b93923ed5e84b8d3f Signed-off-by: -

Some parts of code could be shared with platform derivatives, or new platforms. A new folder plat/st/common is created to put common parts. stm32mp_common.h is a common API aggregate. Remove some casts where applicable. Fix some types where applicable. Remove also some platform includes that are already in stm32mp1_def.h.
