  [PATCH 1/2] ARM: BCM5301X: Specify NAND chip select and ECC in separated files Rafał Miłecki <zajec5@gmail.com> - 2016-06-06 09:50 +0200

#1414712 — [PATCH 1/2] ARM: BCM5301X: Specify NAND chip select and ECC in separated files

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