From 2a5bd596723e13b3f25b9a7f46e9541577bd42c7 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Fri, 9 Feb 2007 14:39:10 +0000 Subject: [MTD] Fix default timeouts for Intel NOR flash In commit c172471b78255a5cf6d05383d9ebbf0c6683167a Nico switched to using common code for polling for command completion. Unfortunately he also used a common default timeout for both write and erase commands, despite the fact that erases can take a _whole_ lot longer. Use a more sensible default for erase timeout.
