From 836ae29ee325b1e3d28ff59468cc50913b1e24ce Mon Sep 17 00:00:00 2001 From: stepan Date: Wed, 8 Dec 2010 05:42:47 +0000 Subject: first round name simplification. drop the _ prefix. the prefix was introduced in the early v2 tree many years ago because our old build system "newconfig" could not handle two files with the same name in different paths like /path/to/usb.c and /another/path/to/usb.c correctly. Only one of the files would end up being compiled into the final image. Since Kconfig (actually since shortly before we switched to Kconfig) we don't suffer from that problem anymore. So we could drop the sb700_ prefix from all those filenames (or, the _ prefix in general) - makes it easier to fork off a new chipset - makes it easier to diff against other chipsets - storing redundant information in filenames seems wrong Signed-off-by: Acked-by: Patrick Georgi Acked-by: Peter Stuge git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6149 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
