-Subject: [PATCH] core: Define section attributes for clang
-
-Clang's attribute section is not same as gcc, here we need to add flags
-to sections so they can be eventually collected by linker into final
-output segments. Only way to do so with clang is to use
-
-pragma clang section ...
-
-The behavious is described here [1], this allows us to define names bss
-sections. This was not an issue until clang-15 where LLD linker starts
-to detect the section flags before merging them and throws the following
-errors
-
-| ld.lld: error: section type mismatch for .nozi.kdata_page
-| >>> /mnt/b/yoe/master/build/tmp/work/qemuarm64-yoe-linux/optee-os-tadevkit/3.17.0-r0/build/core/arch/arm/kernel/thread.o:(.nozi.kdata_page): SHT_PROGBITS
-| >>> output section .nozi: SHT_NOBITS
-|
-| ld.lld: error: section type mismatch for .nozi.mmu.l2
-| >>> /mnt/b/yoe/master/build/tmp/work/qemuarm64-yoe-linux/optee-os-tadevkit/3.17.0-r0/build/core/arch/arm/mm/core_mmu_lpae.o:(.nozi.mmu.l2): SHT_PROGBITS
-| >>> output section .nozi: SHT_NOBITS
-
-These sections should be carrying SHT_NOBITS but so far it was not
-possible to do so, this patch tries to use clangs pragma to get this
-going and match the functionality with gcc.

-binutils ld.bfd generates one RWX LOAD segment by merging several sections
-with mixed R/W/X attributes (.text, .rodata, .data). After version 2.38 it
-also warns by default when that happens [1], which breaks the build due to
---fatal-warnings. The RWX segment is not a problem for the TEE core, since
-that information is not used to set memory permissions. Therefore, silence
-the warning.
