From 2f62a352ea3f62e58c166c430d37ec2d2565eeca Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Tue, 24 Jul 2018 14:06:39 -0700 Subject: mb/51nb: Add support for the 51nb X210 The 51nb X210 is a replacement motherboard for Thinkpad X200/X201 systems, based on a modern Kabylake CPU. It also ships with no firmware protection, (IFD is fully unlocked, no protected regions are set, no Bootguard), making it an ideal coreboot target. This port is based on the support for the Skylake-based Purism Librem 13v3, with the following significant changes: * EC firmware is contained within the system SPI flash, and so a blob of EC firmware must be injected to a defined location during image build. * GPIO layout is different - this is currently just a raw import of the GPIO configuration from the vendor firmware * The system has two DIMMs, so an additional SPD address has been added * The USB port layout is different * The EC must be enabled at boot time through SuperIO-style logical device configuration * EC register layout is different, necessitating changes in the ACPI tables * The HDA pins are different * The genx_dec config is different All hardware appears to work as expected, although the SD reader is untested.
