From a2b3d284ed65b9ada18fd2ffb66daffe9c0ff168 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Thu, 22 Mar 2012 21:00:51 +0100 Subject: [PATCH] mtd: docg3 increase write/erase timeout After several tries with ubifs, it appears empirically that constructor provided figures for erase/write timeouts are underestimated. A timeout of 100ms seems to work with a 5 years worn chip, and no timeouts occur anymore.
