+Subject: [PATCH 1/2] ARM: BCM5301X: Specify NAND chip select and ECC in
+ separated files
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Using separated file with common chip select parameters will allow us
+adding other ECC setups without code duplication.
