Subject: [PATCH v3 09/25] powerpc: Replace PPC64_ELF_ABI_v{1/2} by CONFIG_PPC64_ELF_ABI_V{1/2}
Date: Mon, 9 May 2022 07:36:07 +0200 [thread overview]
Message-ID: <ba13d59e8c50bc9aa6328f1c7f0c0d0278e0a3a7.1652074503.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1652074503.git.christophe.leroy@csgroup.eu>
Replace all uses of PPC64_ELF_ABI_v1 and PPC64_ELF_ABI_v2 by
resp CONFIG_PPC64_ELF_ABI_V1 and CONFIG_PPC64_ELF_ABI_V2.
