From 3a3ab48c68de656736f091c6ed768fa8c110a7ab Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 24 May 2005 20:50:18 +0200 Subject: [MTD] Make map_word_ff ware of the flash buswidth map_word_ff() was setting the mapword to ~0UL regardless of the buswidth of the mapped flash chip. The read_map functions are buswidth aware and therefor the map_word_equal function failed.
