feat(st): enable some warning flags

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

Enable -Wundef, -Wold-style-definition and -Wmissing-prototypes. They should be enabled globally, but there is too much work for the time being. At least having them enabled for a platform should avoid having new instances of those warnings. Change-Id: I716e05392972d2297d86aa3383678af7a9edeb45 Signed-off-by: Yann Gautier

refactor(zlib): move zlib to a lib

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

This allows a dedicated build, and adding compilation flags. The code size does not increase, it has been checked on ST platforms: STM32MP13 and STM32MP25. And the flags -DZ_SOLO -DDEF_WBITS=31 are now dedicated to zlib. Change-Id: I38509b94c0dbcdf46d4b2fb8a4f7ff0e839bc482 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

feat(st): add STM32MP_PSA_FWU_AB_SUPPORT build flag

2026-06-19T07:00:23+00:00

Document and introduce the STM32MP_PSA_FWU_AB_SUPPORT build flag to conditionally support A/B redundancy systems on STM32MP platforms. A fallback mechanism is included in the platform Makefile to automatically override and disable the flag if the core PSA_FWU_SUPPORT option is missing.

feat(st): add optional recovery FIP for NAND boot

2026-06-15T17:57:23+00:00

Without PSA_FWU, the NAND boot path walks backup blocks of the active FIP. Add an optional build flag STM32MP_NAND_FIP_RECOVERY_OFFSET that falls back to a recovery FIP once the active FIP and its backup blocks are exhausted. Before Ia18ff2d the backup walk overran the partition end and could load a FIP placed there. Make this behaviour an explicit opt-in. Tested on STM32MP135.

feat(st): add a halt on panic flag

2026-04-30T09:06:22+00:00

This flag STM32MP_HALT_ON_PANIC will allow either halting the CPU on panic if set to 1 (this is the current behavior), or directly reset the platform if the flag is set to 0. The flag is set by default on the DEBUG flag. Change-Id: I3fae65ab9b557c622403427ff11e1c655d72ae5f Signed-off-by: Yann Gautier

feat(st): add STM32MP_SUPPORT_PM flag

2026-01-23T09:45:59+00:00

This flag will be used to enable low power features. Change-Id: I45d2b6b2ed1da9259a654359f6e611813f92a9c9 Signed-off-by: Yann Gautier

feat(st): disable FWU on serial boot devices

2026-01-23T09:45:59+00:00

When compiling for USB or UART boot devices, it makes no sense to enable Firmware update through PSA_FWU_SUPPORT=1. In this case force the flag to 0, to avoid compilation issues. Change-Id: Id7e35754fd9cf3fb3c26b8ccb947bd39c981231e Signed-off-by: Yann Gautier

refactor(st): simplify rule to build .stm32 file

2026-01-06T12:29:25+00:00

Instead of using substitution for STM32_TF_ELF_LDFLAGS, directly use ld_prefix helper. Use TF_LDFLAGS to avoid adding -nostartfiles and -no-pie options. Add -static to STM32_TF_ELF_LDFLAGS options, and --build-id=none is already handled with TF_LDFLAGS. Change-Id: I6d64b524d98701007aabf150b5c8229799e663d3 Signed-off-by: Yann Gautier

feat(st): use and override default MBedTLS config

2025-07-09T12:08:54+00:00

Each time MbedTLS is updated, the default config may be updated. As STM32MP platforms have their own config file, this needs to be aligned. To avoid this alignment, directly include the default config and override some values for ST platforms, mainly heap size. MBEDTLS_MPI_WINDOW_SIZE is also kept to avoid behavior change.
