2017-08-10nb/intel/sandybridge/raminit: Add Kconfig option for fusesPatrick Rudolph
Add a new Kconfig option to ignore memory fuses that limit the maximum DRAM frequency to be used. The option is disabled by default and should only enabled by experienced users as it might decrease system stability or prevent a successful RAM training. Remove conflicting devicetree settings.

2017-01-24mainboard/lenovo: Add new port L520Patrick Rudolph
Add support for Lenovo Thinkpad L520. The files are generated by autoport, and are successfully tested on the board. L520 has got 4MiB flash chip, that contains a "slim" ME with 1.2MiB only. The flash IC has to be desoldered, as it won't be accessible in circuit. It is located on top of the mainboard right under the touchpad. Test-setup: Extract the following blobs from vendor BIOS: * Intel Flash Descriptor * Intel Management Engine * Intel VBios The laptop has been externaly flashed. It was able to turn on the display and load SeaBIOS. Latest debian has been booted from harddisk. Latest fedora has been booted from USB flash drive. The following hardware has been tested and is working: * Display using Option Rom * PCIe wifi * Ethernet * Keyboard, trackpoint and touchpad * Some Fn functions keys * Volume Keys (except mic mute) * Status LEDs * Audio (headphone jack only) * USB ports * Native raminit dual channel (2 DDR3-1333 DIMMs tested) * SATA cdrom * SATA harddrive Broken: * Some Fn functions keys * Microphone mute button * Speakers (but headphone jack gives sound) Untested: * Expansion slot * SD card slot * Docking station * Native gfx init The EHCI debug port is the first one on the right side.
