+Subject: [PATCH 1/2] Update arm_ffa_user driver dependency
+
+Updating arm-ffa-user to v5.0.1 to get the following changes:
+ - move to 64 bit direct messages
+ - add Linux Kernel v6.1 compatibility
+The motivation is to update x-test to depend on the same driver
+version as TS uefi-test and thus to enable running these in a single
+configuration.
+Note: arm_ffa_user.h was copied from:
+ - URL:https://git.gitlab.arm.com/linux-arm/linux-trusted-services.git
+ - SHA:18e3be71f65a405dfb5d97603ae71b3c11759861

+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.

+Subject: [PATCH] optee: enable clang support
+
+When compiling with clang, the LIBGCC_LOCATE_CFLAG variable used
+to provide a sysroot wasn't included, which results in not locating
+compiler-rt. This is mitigated by including the variable as ammended.

+Subject: [PATCH] core: link: add --no-warn-rwx-segments
+
+Signed-off-by: Anton Antonov <Anton.Antonov@arm.com>
+Upstream-Status: Backport [https://github.com/OP-TEE/optee_os/pull/5474]
+
+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.
+
