   4 Subject: [PATCH 1/2] ARM: BCM5301X: Specify NAND chip select and ECC in
   5  separated files
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit

  10 Using separated file with common chip select parameters will allow us
  11 adding other ECC setups without code duplication.
