From 27807c66ee5d73c54de942b56359e447d27b1477 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 22 Dec 2015 17:27:02 -0800 Subject: purism/librem13: Add support for Purism Librem 13 mainboard This adds support for booting the Purism Librem 13 mainboard with coreboot, using binaries extracted from the original BIOS and from a Broadwell Chromebook. The following features have been tested on Ubuntu 15.10: - Input: Keyboard and Trackpad - SATA: Internal HDD and M.2 NGFF - Network: WiFi and Ethernet - USB: Bluetooth, Camera, SD Card, Ports (1xUSB2 and 1xUSB3) - Video: Internal panel and HDMI port - Internal speakers and microphone (headphones do not work) - EC handling for battery, AC, lid, special keys These binaries are extracted from the original BIOS: - VGA BIOS - Management Engine - Intel Firmware Descriptor These binaries are extracted from a Broadwell Chromebook BIOS: - MemoryInit reference code binary - SiliconInit reference code binary This was developed and tested on an Librem 13 device. For those who may want to do more development you can use EHCI debug and the right USB port to get coreboot output.
