From 13bfb34c10fae6016710f5f070043c8b94b40583 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 29 Oct 2005 16:14:08 +0100 Subject: [PATCH] [ARM] Fix Assabet reboot with SA1100 MTD map driver Unfortunately, some devices forgot to reset the flash on reboot. Arrange for the map driver to suspend & resume the flash to ensure that it is in a sane state before rebooting.
