2018-05-11acpi: Add support for writing ACPI _PLD structuresDuncan Laurie
This commit adds support for writing ACPI _PLD structures that describe the physical location of a device to the OS. This can be used by any device with a physical connector, but is required when defining USB ports for the OS. A simple function is provided that generates a generic _PLD structure for USB ports based on the USB port type.

This commit adds support for writing ACPI _UPC structures that help describe USB ports for the OS. This is a simple structure format which indicates what type of port it is and whether it is connectable. It should be paired with an ACPI _PLD structure to define USB ports for the OS.

2018-04-26arch/x86: allow idt to be available to link in all stagesAaron Durbin
Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having the interrupt handling code available to all stages. In order to do this the idt setup is moved to a C module. The vecX entries are made global so that a table of references to all the interrupt vector entry points can be used to dynamically initialize the idt. The ramification for ramstage is that exceptions are initialized later (lib/hardwaremain.c). Not all stages initialize exceptions when this Kconfig variable is selected, but bootblock for the C, stages using assembly_entry.S, and of course ramstage do. Anything left out just needs a call to exception_init() at the right location.

2017-05-30arch: Unify basic cache clearing APIJulius Werner
Caching is a very architecture-specific thing, but most architectures have a cache in general. Therefore it can be useful to have a generic architecture-independent API to perform simple cache management tasks from common code. We have already standardized on the dcache_clean/invalidate naming scheme that originally comes from ARM in libpayload, so let's just do the same for coreboot. Unlike libpayload, there are other things than just DMA coherency we may want to achieve with those functions, so actually implement them for real even on architectures with cache-snooping DMA like x86. (In the future, we may find applications like this in libpayload as well and should probably rethink the API there... maybe move the current functionality to a separate dma_map/unmap API instead. But that's beyond scope of this patch.)

Since reading/toggling of GPIOs is platform-dependent task, provide an interface with common functions to generate ACPI AML code for manipulating GPIOs: 1. acpigen_soc_read_rx_gpio 2. acpigen_soc_get_tx_gpio 3. acpigen_soc_set_tx_gpio 4. acpigen_soc_clear_tx_gpio Provide weak implementations of above functions.

2016-07-08acpi: Change device properties to work as a treeDuncan Laurie
There is a second ACPI _DSD document from the UEFI Forum that details how _DSD style tables can be nested, creating a tree of similarly formatted tables. This document is linked from acpi_device.h. In order to support this the device property interface needs to be more flexible and build up a tree of properties to write all entries at once instead of writing each entry as it is generated. In the end this is a more flexible solution that can support drivers that need child tables like the DA7219 codec, while only requiring minor changes to the existing drivers that use the device property interface. This was tested on reef (apollolake) and chell (skylake) boards to ensure that there was no change in the generated SSDT AML.
