From 4b0abf9f3c024225987ec92ea9ae9e8a1ac5950d Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 3 Oct 2014 19:21:03 +0900 Subject: mtd: denali: add Denali controller configs to Kconfig Commit 3eb3e72a3f66 (nand/denali: Adding Denali NAND driver support) introduced some new options, and some of them were documented by commit f9860cf081ef (nand/denali: Document CONFIG symbols). This commit allows users to enable/disable them via Kconfig with more detailed help docs.
