From b80a32b9cc634adfa8eaef33ec981e7febf2ade2 Mon Sep 17 00:00:00 2001 From: Justin Waters Date: Tue, 26 Feb 2008 13:07:02 -0500 Subject: Update the i.MX31 Kernel to 2.6.23 This is the result of a brute-force attempt to update the kernel to 2.6.23. Now that we have a git tree, our effort will be a little nicer in the future.
