+Subject: [PATCH] Fix building AArch32 CE implementations when target is ARMv6
+ arch
+
+* cipher/cipher-gcm-armv8-aarch32-ce.S: Select ARMv8 architecure.
+* cipher/rijndael-armv8-aarch32-ce.S: Ditto.
+* cipher/sha1-armv8-aarch32-ce.S: Ditto.
+* cipher/sha256-armv8-aarch32-ce.S: Ditto.
+* configure.ac (gcry_cv_gcc_inline_asm_aarch32_crypto): Ditto.
+--
+
+Raspbian distribution defaults to ARMv6 architecture thus 'rbit'
+instruction is not available with default compiler flags. Patch
+adds explicit architecture selection for ARMv8 to enable 'rbit'
+usage with ARMv8/AArch32-CE assembly implementations of SHA,
+GHASH and AES.
