From 11192146e57bc8e58865e7d9c2497f66a4f7e6e7 Mon Sep 17 00:00:00 2001 From: Rod Whitby Date: Sat, 10 Feb 2007 09:26:48 +0000 Subject: [PATCH] [MTD] Fix RedBoot partition parsing regression harder. Correct the location of the recalculation of the FIS directory size, and also add the same recalculation for the byte-swapped case.
