fix(stm32mp1): manage all flags for PKA algos

2026-09-07T11:41:30+00:00

PKA_USE_BRAINPOOL_P256R1 and PKA_USE_NIST_P521 were not defined in platform.mk, leading to compilation warnings with -Wundef. Add them in add_defines macro, but disabled. Change-Id: I43622b3b72f1a9b6348f9f04863a7ca55edd7d82 Signed-off-by: Yann Gautier

refactor(build): remove redundant `eval` calls

2026-08-20T16:52:07+00:00

Execute expressions directly without `eval` when they do not expand to Make syntax (i.e. where `eval` is provably pointless). Additionally, remove the obsolete `eval` feature check - we mandate at least GNU Make 4.3, which always supports it. Change-Id: I26f1723f084d0428a2cbe336e76f0765a9818a5a Signed-off-by: Chris Kay

fix(stm32mp1): force soft float ABI and disable NEON

2026-07-17T15:40:58+00:00

NEON is not used in TF-A for STM32MP1 platforms. This was already the case since using arm-none-eabi toolchain, which enables `__SOFTFP__`. ARM_WITH_NEON can then be removed, and always force -mfloat-abi=soft as this can cause issues [1] [2] with arm-*-gnueabihf toolchains. As it can break compilation when using MbedTLS v3.6.6, this can also be a candidate for LTS.

fix(stm32mp1): disable STM32MP_DDR_FIP_IO_STORAGE

2026-06-24T07:46:02+00:00

Explicitly disable STM32MP_DDR_FIP_IO_STORAGE flag on STM32MP1 that is only used on STM32MP2. This avoids warnings when enabling -Wundef flag. Change-Id: I191a2cf8d555a90b9cbcccc37e1e310f5ec1abd6 Signed-off-by: Yann Gautier

fix(st): make STM32MP1X/STM32MP2X boolean flags

2026-06-24T07:46:02+00:00

Instead of defining those 2 flags with TF_CFLAGS += -D, use the call assert_booleans/add_defines helpers. The #ifdef in C files are changed to #if. And to avoid flags being unset, always define all the SoC flags whatever the platform is. This avoid warnings when -Wundef flag is set.

feat(st): enable A/B redundancy support

2026-06-19T07:00:27+00:00

Transition the STM32MP firmware management from a single-image to a multi-image bank structure to support a fully redundant A/B layout on STM32MP1 and STM32MP2 platforms. By increasing the images per bank count to 3, the FWU framework can now manage the FIP, BootFS, and RootFS partitions as a single redundant unit. To support this layout, define the required IO policies, block specifications, and partition GUIDs (XBOOTLDR and Linux FS) inside the common platform files. The definitions and the storage layout adjustments are conditionally guarded by the STM32MP_PSA_FWU_AB_SUPPORT flag to optimize internal SRAM usage when unused. Additionally, adjust the STM32_EXTRA_PARTS count on both STM32MP1 and STM32MP2 platform files to accommodate the mirrored layout slots when A/B redundancy is enabled.

Merge "fix(st): restore support for multiple entries in DTB_FILE_NAME" into integration

2026-02-24T15:37:50+00:00

fix(st): restore support for multiple entries in DTB_FILE_NAME

2026-02-06T16:22:42+00:00

Commit e772a6d1864a ("stm32mp1: platform.mk: support generating multiple images in one build") allowed DTB_FILE_NAME to contain multiple entries, thereby allowing to build all the executable code once and then link it against each device tree one by one. This makes for easier build system integration as one recipe/package can generate multiple images at once. This was broken by below mentioned commit, because it assumed DTB_FILE_NAME to contain only a single entry. Rework the -sp_min suffix logic to fix this regression.

feat(stm32mp1): make stpmic2 usable for STM32MP1

2026-02-04T13:51:36+00:00

Update STPMIC2 driver to use it on STM32MP1 especially STM32MP_STPMIC1L. Change-Id: I0db727a093a6a85dca7a74be280c0d1af0e54417 Signed-off-by: Pascal Paillet

feat(stm32mp1): enable MCE driver for STM32MP13

2025-07-22T07:28:39+00:00

Enabled as BL2 sources. Add MCE base address and key size in platform definitions. Change-Id: Icb7d9d7a56806a86e6d0a76640a375a5b5e88a2a Signed-off-by: Nicolas Le Bayon
