In order to prevent keyboard keys pressed at boot from causing issues in the payload remove the PS2 keyboard driver so it does not get initialized until it is needed in libpayload. This was enabled initially because the keyboard controller on this platform does not come up in translated mode, so unless coreboot called keyboard_init() the keyboard would never work properly in the kernel because it would come up as an "AT Raw" device instead of an "AT Translated" device. Instead of initializing the keyboard in coreboot a workaround is added to the payload to put the keyboard into translated mode.

2019-03-01soc/intel/skylake: Unify serial IRQ optionsNico Huber
We had two ways to configure the serial IRQ mode. One time in the devicetree for FSP and one time through Kconfig for coreboot. We'll use `enum serirq_mode` from soc/intel/common/ as a devicetree option instead. As the default is `quiet mode` here and that is the most common mode, this saves us a lot of lines. In four cases kblrvp8, 11 and librem 13v2, 15v3, we had conflicting settings in devicetree and Kconfig. We'll maintain the `continuous` selection, although it might be that coreboot overrode this earlier on the kblrvps. Note: A lot of Google boards have serial IRQ enabled, while the pin seems to be unconnected?

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2019-02-13mb/google/sarien: Support multiple touchscreen at same addressDuncan Laurie
The Sarien board may have different touchscreen devices that use the same I2C slave address but have different requirements such as needing a special driver or ACPI configuration. In order to support this the devicetree may be configured with multiple devices at the same address and at boot time the unused devices will be disabled. Because there is no GPIO for selecting the device that is present it can instead be selected with Kconfig, or by setting a VPD key to the HID of the touchscreen device that is present. The default for Sarien devices is to not enable a touchscreen for the OS. The touchscreen selection is currently limited to the Sarien variant but this also adds the touchscreen HID for Arcada to Kconfig so it would not complain about the key not being set. BUG=b:122019253 TEST=This was tested on a Sarien board by adding a second entry to the devicetree at the same address. Without this change the SSDT is not loaded by the kernel because of the address conflict.

2019-02-08mb/google/hatch: Replace part-specific SPD files with generic onesShelley Chen
Traditionally, we have always allocated 1 DRAM ID per part number. However, on nami, we have run out of DRAM IDs because we have supported so many different parts. We are now adopting the use of generic SPD files that are feature-based rather than specific to each part, allowing us to support multiple parts with a single SPD. The common SPDs were created by taking current SPDs in Nami (which is using the same DDR4 parts as Hatch) and zeroing out all the manufacturer information and part names. Additionally, we zeroed out bytes 128 (raw card extension, module nominal height), 129 (module maximum thickness), and 130 (reference raw card used) after verifying that they are not used in FSP. We verified with these fields zeroed out, all nami devices could boot up without errors. We also verified on the two Hatch skus that we have (4G 2400, 8G 2666) that the generic SPDs boot properly. BUG=b:122959294 BRANCH=None TEST=Make sure that we can boot up on both 4G Samsung and 8G Hynix DDR4 devices that we currently have.
