stm32mp15: replace CONFIG_TFABOOT when it is possible

2021-11-10T16:07:31Z

In some part of STM32MP15 support the CONFIG_TFABOOT can be replaced by other config: CONFIG_ARMV7_PSCI and CONFIG_ARM_SMCCC. This patch also simplifies the code in cpu.c, stm32mp1_ram.c and clk_stml32mp1.c as execution of U-Boot in sysram (boot without SPL and without TFA) is not supported: the associated initialization code is present only in SPL. This cleanup patch is a preliminary step to support SPL load of OP-TEE in secure world, with SPL in secure world and U-Boot in no-secure world.

gpio: stm32: create include file for driver private data

2021-11-10T16:03:36Z

The stm32 gpio driver private data are not needed in arch include files, they are not used by code except for stm32 gpio and pincontrol drivers, using the same IP; the defines for this IP is moved in a new file "stm32_gpio_priv.h" in driver/gpio. This patch avoids to have duplicated file gpio.h for each SOC in MPU directory mach-stm32mp and in each MCU directory arch-stm32* and allows to remove CONFIG_GPIO_EXTRA_HEADER for all STM32.

board: stmp32mp1: split board and SOC STM32MP15 configuration

2021-11-10T16:03:36Z

Add a configuration file "stm32mp15_st_common.h" to handle the STMicroelectronics boards configuration and rename stm32mp1.h to "stm32mp15_common.h" to handle the generic STM32MP15x series configuration. The configuration file "dh_stm32mp1.h" is also renamed to "stm32mp15_dh_dhcom" for the configuration of board based on the dhelectronics STM32MP15x SOM. In the STMicroelectronics board configuration the default bootcmd "bootcmd_stm32mp" is updated to only select the extlinux file found on SD-Card on STM32MP15x EV1 for boot from NOR device.

board: stm32mp1: Remove gpio_hog_probe_all() from board

2021-10-08T06:46:02Z

DM_GPIO_HOG flag has been replaced by GPIO_HOG flag since a while in commit 49b10cb49262 ("gpio: fixes for gpio-hog support"). And furthermore, gpio_hog_probe_all() is already called in board_r.c. So gpio_hog_probe() can be removed from stm32mp1.c. Signed-off-by: Patrice Chotard Reviewed-by: Patrick Delaunay

The stm32 platforms never had to support an ATAGs-based Linux Kernel, so remove the bi_boot_params initialization. Signed-off-by: Patrick Delaunay Reviewed-by: Patrice Chotard Tested-by: Patrice Chotard Tested-by: Alexandru Gagniuc

tee: add a stub for tee_find_device

Add stub for tee_find_device function when CONFIG_TEE is not activated to simplify the caller code. This patch allows to remove the CONFIG_IS_ENABLED(OPTEE) tests for stm32 platform. Signed-off-by: Patrick Delaunay Acked-by: Etienne Carriere Reviewed-by: Jens Wiklander

treewide: fdt: Move fdt_get_config_... to ofnode_conf_read...

2021-09-25T15:46:15Z

The current API is outdated as it requires a devicetree pointer. Move these functions to use the ofnode API and update this globally. Add some tests while we are here. Correct the call in exynos_dsim_config_parse_dt() which is obviously wrong. Signed-off-by: Simon Glass

arm: Disable ATAGs support

2021-09-07T20:22:30Z

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and stemmy, disable ATAG support. A large number of platforms had enabled support but never supported a kernel so old as to require it. Further, some platforms are old enough to support both, but are well supported by devicetree booting, and have been for a number of years. This is because some of the ATAGs related functions have been re-used to provide the same kind of information, but for devicetree or just generally to inform the user. When needed still, rename these functions to get_board_revision() instead, to avoid conflicts. In other cases, these functions were simply unused, so drop them.

arm: stm32mp: add defconfig for trusted boot with FIP

2021-08-16T07:36:31Z

Add TF-A FIP support for trusted boot on STM32MP15x, when STM32MP15x_STM32IMAGE is not activated. With FIP support the SSBL partition is named "fip" and its size is 4MB, so the ENV partition name in device tree (for SD card or eMMC) or offset in defconfig (CONFIG_ENV_OFFSET / CONFIG_ENV_OFFSET_REDUND) need to be modified. With FIP the TEE MTD partitions are removed because the OP-TEE binray are included in the FIP containers. Signed-off-by: Patrick Delaunay Reviewed-by: Patrice Chotard
