   4 Subject: [PATCH 08/15] mtd: spinand: Delay a little bit the dirmap creation
   5
   6 As we will soon tweak the dirmap creation to act a little bit
   7 differently depending on the picked ECC engine, we need to initialize
   8 dirmaps after ECC engines. This should not have any effect as dirmaps
   9 are not yet used at this point.
