From 489c696ae7211218961d159e43e722d74c36fcbc Mon Sep 17 00:00:00 2001 From: Sergei Poselenov Date: Wed, 14 Feb 2007 14:30:28 +0300 Subject: [PATCH] MCC200: Extensions to Software Update Mechanism Update / extend Software Update Mechanism for MCC200 board: - Add support for rootfs image added. The environment variables "rootfs_st" and "rootfs_nd" can be used to override the default values of the image start and end. - Remove excessive key check code. - Code cleanup. --- board/mcc200/auto_update.c | 93 +++++++++++++++++++------------------- 1 file changed, 46 insertions(+), 47 deletions(-) diff --git a/board/mcc200/auto_update.c b/board/mcc200/auto_update.c index f1bb721284..12091fd782 100644 --- a/board/mcc200/auto_update.c +++ b/board/mcc200/auto_update.c @@ -47,25 +47,6 @@ #error "must define CFG_CMD_FAT" #endif -/* - * Check whether a USB memory stick is plugged in. - * If one is found: - * 1) if prepare.img ist found load it into memory.
