From 8decd25477fe5a8bb314e65c9b1a2c9d54bc9124 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 9 Jun 2015 00:21:47 +0200 Subject: grub2: prepare and install El Torito image In order to support ISO9660 bootable images that rely on Grub 2, this commit modifies thr Grub 2 makefile to generate and install an El Torito image. Such an image is simply produced by concatenating the cdboot.img provided by Grub 2, and the Grub 2 image generated by Buildroot using grub-mkimage. Since this action is so simple and cost-free, we don't bother adding a Grub 2 sub-option for that, and simply generate the El Torito image unconditionally.
