The call made at mp_ops.post_mp_init() generally uses four different names. Unify these with followups. smm_southbridge_enable(SMI_EVENTS) smm_southbridge_enable_smi() hudson_enable_smi_generation() enable_smi_generation() Furthermore, some platforms do not enable power button SMI early. It may be preferred to delay the enablement, but fow now provide global_smi_enable_no_pwrbtn() too.

2020-06-15arch/x86: Remove XIP_ROM_SIZEKyösti Mälkki
When adding XIP stages on x86, the -P parameter was used to pass a page size that covers the entire file to add. The same can now be achieved with --pow2page and we no longer need to define a static Konfig for the purpose. TEST: Build asus/p2b and lenovo/x60 with "--pow2page -v -v" and inspect the generated make.log files. The effective pagesize is reduced from 64kB to 16kB for asus/p2b giving more freedom for the stage placement inside CBFS. Pagesize remained at 64kB for lenovo/x60.

The changes include: 1. combine the microcode_xxx.c and update_microcode.c into one source. 2. Redefine the microcode updating function to eliminate the parameter. Get the revision ID in the black box. Reduce the depth of function calls. 3. Get the revision ID by bitwise calculation instead of lookup table. 4. Reduce the confusing type casts. 5. Squash some lines. We do not change the way it used to be. The code assume only one microcode is integrated in CBFS. If needed in future, 41719 is the example of integrating multiple binaries.

2020-06-04acpi: Accomodate non-standard UUIDs in device propertiesDuncan Laurie
There have been changes to the way device properties are supported in Linux[1] and Windows[2] which add flexibilty: - non-standard UUIDs can be used instead of only ACPI_DP_UUID - support for multiple different packages within the _DSD that associate different properties with unique UUIDs. To handle this I extracted the part that does the write of UUID and properties to a separate function and defined a new PACKAGE type which has the custom UUID as a name and can be used the same way that child properties are today. For example a PCIe root port for a USB4 port has a standard property indicating the USB4 reference, and then two custom properties which are defined for different attributes. Example code: /* Create property table */ acpi_dp *dsd = acpi_dp_new_table("_DSD"); acpi_dp_add_reference(dsd, "usb4-port", usb4_path); /* Add package for hotplug */ acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"); acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1); acpi_dp_add_package(dsd, pkg); /* Add package for external port info */ pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389"); acpi_dp_add_integer(pkg, "ExternalFacingPort", 1); acpi_dp_add_package(dsd, pkg); /* Write all properties */ acpi_dp_write(dsd); Resulting ACPI: Scope (\_SB.PCI0.TRP0) { Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") Package () { Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA } }, ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"), Package () { Package () { "HotPlugSupportInD3", One } }, ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"), Package () { Package () { "ExternalFacingPort", One }, } }) } [1] https://patchwork.kernel.org/patch/10599675/ [2] https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports Change-Id: I75f47825bf4ffc5e9e92af2c45790d1b5945576e Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42047 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2020-06-02fw_config: Add firmware configuration interfaceDuncan Laurie
This change introduces a new top-level interface for interacting with a bitmask providing firmware configuration information. This is motivated by Chromebook mainboards that need to support multiple different configurations at runtime with the same BIOS. In these devices the Embedded Controller provides a bitmask that can be broken down into different fields and each field can then be broken down into different options. The firmware configuration value could also be stored in CBFS and this interface will look in CBFS first to allow the Embedded Controller value to be overridden. The firmware configuration interface is intended to easily integrate into devicetree.cb and lead to less code duplication for new mainboards that make use of this feature.

2020-05-28device: Enable resource allocation above 4G boundary with allocator v4Furquan Shaikh
This change adds back CB:39487 which was reverted as part of CB:41412. Now that the resource allocator is split into old(v3) and new(v4), this change adds support for allocating resources above 4G boundary with the new allocator v4. Original commit message: This change adds support for allocating resources above the 4G boundary by making use of memranges for resource windows enabled in the previous CL. It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the following ways: a) Downstream device resources can set this flag to indicate that they would like to have their resource allocation above the 4G boundary. These semantics will have to be enabled in the drivers managing the devices. It can also be extended to be enabled via devicetree. This flag is automatically propagated by the resource allocator from downstream devices to the upstream bridges in pass 1. It is done to ensure that the resource allocator has a global view of downstream requirements during pass 2 at domain level. b) Bridges have a single resource window for each of mem and prefmem resource types. Thus, if any downstream resource of the bridge requests allocation above 4G boundary, all the other downstream resources of the same type under the bridge will be allocated above 4G boundary. c) During pass 2, resource allocator at domain level splits IORESOURCE_MEM into two different memory ranges -- one for the window below 4G and other above 4G. Resource allocation happens separately for each of these windows. d) At the bridge level, there is no extra logic required since the resource will live entirely above or below the 4G boundary. Hence, all downstream devices of any bridge will fall within the window allocated to the bridge resource. To handle this case separately from that of domain, initializing of memranges for a bridge is done differently than the domain. Limitation: Resources of a given type at the bridge or downstream devices cannot live both above and below 4G boundary. Thus, if a bridge has some downstream resources requesting allocation for a given type above 4G boundary and other resources of the same type requesting allocation below 4G boundary, then all these resources of the same type get allocated above 4G boundary.

2020-05-26device: Move resource allocation into a separate compilation unitFurquan Shaikh
This change moves the resource allocator functions out of device.c and into two separate files: 1. resource_allocator_v3.c: This is the old implementation of resource allocator that uses a single window for resource allocation. It is required to support some AMD chipsets that do not provide an accurate map of allocated resources by the time the allocator runs. They work fine with the old allocator since it restricts itself to allocations in a single window at the top of the 4G space. 2. resource_allocator_common.c: This file contains the functions that can be shared by the old and new resource allocator. Entry point into the resource allocation is allocate_resources() which can be implemented by both old and new allocators. This change also adds a Kconfig option RESOURCE_ALLOCATOR_V3 which enables the old resource allocator. This config option is enabled by default currently, but in the following CLs this will be enabled only for the broken boards. Reason for this split: Both the old and new resource allocators need to be retained in the tree until the broken chipsets are fixed.

2020-05-21acpi/soundwire: Add functions to generate SoundWire propertiesDuncan Laurie
This change uses the previously added SoundWire definitions to provide functions that generate ACPI Device Properties for SoundWire controllers and codecs. A SoundWire controller driver should populate `struct soundwire_controller` and pass it to soundwire_gen_controller(). This will add all of the defined master links provided by the controller. A SoundWire codec driver should populate the necessary members in struct soundwire_codec and pass it to soundwire_gen_codec(). Several properties are optional and depend on whether the codec itself supports certain features and behaviors. The goal of this interface is to handle all of the properties defined in the SoundWire Discovery and Configuration Specification Version 1.0 so that controller and codec drivers do not need to all have code for writing standard properties. Both of these functions also provide a callback method for adding custom properties that are not defined by the SoundWire DisCo Specification. These properties may be required by OS drivers but are outside of the scope of the SoundWire specification itself. This code is tested with controller, codec, and mainboard implementations in subsequent commits.
