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.
