commit 73f9008fdfa5ba7d15cfb10326af55e28592614d Author: Nico Huber nico.huber@secunet.com Date: Wed Jun 19 15:57:34 2013 +0200
sandybridge: Make inclusion of me.bin optional
Current build configuration always wants to include an Intel Management Engine firmware (me.bin) on Sandy Bridge systems. However, we can have a working coreboot without it, as long as the factory delivered ME firmware is kept untouched in the flash ROM. So let the user decide if a ME firmware will be included in the build.
