From 881bac2db254a4bfa52567233a0b264484c31fa1 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 23 Oct 2007 06:23:29 +0000 Subject: Allow targets to specify extra initramfs source files The CONFIG_INITRAMFS_SOURCE Kconfig variable can be a space-separated list of source files (or directories). This allows a platform to add extra components to the initramfs image, by defining the INITRAMFS_EXTRA_FILES make var. By default, we add a simple initramfs extra file for the generic-2.6 platform, which specifies a few device nodes.
