2020-03-24drivers/intel/gma: Ditch `link_frequency_270_mhz` settingNico Huber
The `link_frequency_270_mhz` setting was originally used by the native graphics init code for Sandy/Ivy Bridge, which is long gone. The value of this information (which board had it set) is questionable. The only board that had an LVDS panel and set it to 0 was the ThinkPad L520, where native graphics init was never reported to work. Also, the native graphics init only used it for calculations, but never confi- gured the hardware to use a specific frequency. A look into the docu- mentation also doesn't reveal any straps that could be used to confi- gure it.

2019-07-19sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supportedPatrick Rudolph
The processor P_BLK doesn't support throttling. This behaviour could be emulated with SMM, but instead just update the FADT to indicate no support for legacy I/O based throttling using P_CNT. We have _PTC defined in SSDT, which should be used in favour of P_CNT by ACPI aware OS, so this change has no effect on modern OS. Drop all occurences of p_cnt_throttling_supported and update autoport to not generate it any more.

2019-01-24cpu/intel/model_206ax: Remove the notion of socketsArthur Heymans
With the memory controller the separate sockets becomes a useless distinction. They all used the same code anyway. UNTESTED: This also updates autoport.

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.
