From 0f8af71f1a40e8ae960ba616cb9a5bf14f10fb13 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Tue, 29 Jan 2013 02:29:49 +0800 Subject: cbfstool: Use cbfs_image API for "extract" command. Change the "extract" command to use cbfs_export_entry API. Nothing changed in its usage. To verify, run "cbfstool coreboot.rom extract -f blah -n blah" and check if the raw type file is correctly extracted.
