From c5ecc11dec2402aa05e68bd03b65a6460837b748 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Mon, 31 Jan 2011 00:07:54 -0600 Subject: meta-intel: add a /common dir with grub2/live-install changes Add a /common dir to contain code shared by multiple BSPs in the meta-intel repo, along with a couple recipes to live there temporarily. In this case, there are two BSPs that need to share the common grub2 and associated initramfs-live-install changes (sugarbay and jasperforest). The grub2 and associated initramfs-live-install changes will soon be submitted to the main poky repo, but for now it makes more sense to keep them here - they're needed for live-install of the two BSPs mentioned, but they contain a couple hacks that need to be addressed and are untested with anything else.
