Stefan Agner 5d47e129a7 ARM: trusted_foundations: do not use naked function ... (commit 4ea7bdc6b5 upstream) As documented in GCC naked functions should only use basic ASM syntax. The extended ASM or mixture of basic ASM and "C" code is not guaranteed. Currently this works because it was hard coded to follow and check GCC behavior for arguments and register placement. Furthermore with clang using parameters in Extended asm in a naked function is not supported: arch/arm/firmware/trusted_foundations.c:47:10: error: parameter references not allowed in naked functions : "r" (type), "r" (arg1), "r" (arg2) ^ Use a regular function to be more portable. This aligns also with the other SMC call implementations e.g. in qcom_scm-32.c and bcm_kona_smc.c.
