From 20f25dd5c8a513ee136e9f6d8c67959591298617 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 22 Apr 2014 10:41:05 -0700 Subject: Rename coreboot_ram stage to ramstage Rename coreboot_ram stage to ramstage. This is done in order to provide consistency with other stage names (bootblock, romstage) and to allow any Makefile rule generalization, required for patches to be submitted later.
