From 661aa880398add5c27943cb077c451a45cc112a1 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Mon, 9 May 2022 07:36:06 +0200 Subject: powerpc: Add CONFIG_PPC64_ELF_ABI_V1 and CONFIG_PPC64_ELF_ABI_V2 At the time being, we use CONFIG_CPU_LITTLE_ENDIAN and CONFIG_CPU_BIG_ENDIAN to pass -mabi=elfv1 or elfv2 to compiler, then define a PPC64_ELF_ABI_v1 or PPC64_ELF_ABI_v2 macro in asm/types.h based on _CALL_ELF define set by the compiler. Make it more straight forward with a CONFIG option that is directly usable.
