The initrd image used by the Linux kernel is list of file system images concatenated together and presented as a single initrd file at boot time. So far the initrd is a single filesystem image. But in cases like to support early microcode loading, the initrd image need to have multiple filesystem images concatenated together. This commit is extending the INITRD variable from a single filesystem image to a list of filesystem images to satisfy the need mentioned above.
