From 6411bf6cdfe9b444bc3aa0c23f8cf35460d69432 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 26 Oct 2010 11:42:51 +0100 Subject: Revert "mtd: cleanup Kconfig dependencies" This reverts commit 432dc821c90114f9b0e00f6752a700e937516ade. The individual CFI geometry options were carefully set up to get sane default values if the CFI_ADV_OPTIONS wasn't set, and it wasn't appropriate to move them into an if/endif block.
