Hi all,
We've created a change, which is using original CMSIS headers in TF-M. Current patch is only for arm/mps3/an552 platform. Our plan is to create a public review only for this (which will NOT be merged), and after the review, we would like to extend this patch to all of the platforms.
The main changes in the chain: - copy and zero_table size fix in the GNU linker scripts and initial startup code - Removed __INITIAL_SP and __STACK_LIMIT patch form gcc and iar cmsis files, NS linker scripts using CMSIS style naming, the secure and bl2 build's linker scripts remains untouched (ARMCLANG style naming, __INITIAL_SP and __STACK_LIMIT patched with cmsis_stack_override interface library) - NS process stack removed from NS linkers (PSP) - Common startup file for bl2 and ns builds - Add original cmsis headers, updated system and startup files - Stack sealing done twice, once from startup (to resemble CMSIS startup template) and once from TF-M secure main
Feedback is welcome: https://review.trustedfirmware.org/q/topic:%2522use-original-cmsis-headers%2...
