From 42b1c43c4dad6a58f444e868b84c6bbd10009681 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Thu, 9 Dec 2010 18:09:14 +0000 Subject: Merge enable_rom.c files into bootblock.c files. All southbridges using TINY_BOOTBLOCK have a bootblock.c files which simply includes an enable_rom.c files. As discussed on the mailing list, drop the enable_rom.c file by merging it into bootblock.c.
