+Subject: [PATCH] kernel: build crypto md5/sha1/sha256 modules for powerpc
+
+This builds and enables kernel optimized modules for mpc85xx target:
+- CONFIG_CRYPTO_MD5_PPC [1]
+- CONFIG_CRYPTO_SHA1_PPC_SPE [2]
+- CONFIG_CRYPTO_SHA256_PPC_SPE [3]
+
+Where it was possible, then use Signal Processing Engine, because
+CONFIG_SPE is already enabled in mpc85xx config.
