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

feat(build): enable -Wundef for C files if W >= 1

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

Add -Wundef to BL_FLAGS. This will then be enabled for all TF-A C files through MAKE_C macro, but not for libs. This flag is enabled only when W is defined in the build command line and greater or equal to 1. Change-Id: I6c327584b1e1bb0e1eb59c774a6c6a6788139b99 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(compiler-rt): move compiler_rt to a lib

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

This allows a dedicated build, and avoid BL_FLAGS compilation flags. The code size does not increase, it has been checked on ST platforms: STM32MP13 and STM32MP25. Change-Id: I5ff3c40222770400a97dd4d451aeebc26fef4f2a Signed-off-by: Yann Gautier

feat(build): introduce BL_FLAGS

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

This flag is only used by MAKE_C macro, and won't be propageted to other targets like MAKE_C_LIB. This allows handling -Wundef flag, that we want to enable but that is known to bring warnings with some libs (zlib or compiler-rt).
