Add support for multiple, shared, early initrd images. These early images will be loaded in the order declared, and all will be loaded before the initrd image. While many classes of data can be provided by early images, the immediate use case would be for distributions to provide CPU microcode to mitigate the Meltdown and Spectre vulnerabilities. There are two environment variables provided for declaring the early images. * GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare images that are provided by the distribution or installed packages. If undeclared, this will default to a set of common microcode image names. * GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User images will be loaded after the stock images. These separate configurations allow the distribution and user to declare different image sets without clobbering each other. This also makes a minor update to ensure that UUID partition labels stay disabled when no initrd image is found, even if early images are present. This is a continuation of a previous patch published by Christian Hesse in 2016: http://lists.gnu.org/archive/html/grub-devel/2016-02/msg00025.html Down stream Gentoo bug: https://bugs.gentoo.org/645088 Signed-off-by: Robin H.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
