2020-04-10Drop unnecessary DEVICE_NOOP entriesNico Huber
Providing an explicit no-op function pointer is only necessary for `.read_resources` and `.set_resources`. All other device-operation pointers are optional and can be NULL.

2020-04-02Trim `.acpi_fill_ssdt_generator` and `.acpi_inject_dsdt_generator`Nico Huber
These two identifiers were always very confusing. We're not filling and injecting generators. We are filling SSDTs and injecting into the DSDT. So drop the `_generator` suffix. Hopefully, this also makes ACPI look a little less scary.

2019-12-22superio/common: Add more ACPI methodsPatrick Rudolph
* Make use of introduced SSDT config mode access * Make use of introduced SSDT mutex * Provide ACPI functions to safely access SIO config space * Implement method to query LDN enable state * Implement method to set LDN enable state * Use introduced functions to implement _DIS and _STA in the device * Update documentation Tested on Aspeed AST2500 and Linux 5.2. Manually verified ACPI code that generates no errors in Linux.

ITR2 is specified twice here, which leads to the following error message in Linux: [ 0.263591] ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.LPCB.SIO0.ITR2], AE_ALREADY_EXISTS (20190509/dsfield-633) Add comments and fix duplicated field.

2019-09-06superio/common: Add ssdtgen for generic SuperIOsPatrick Rudolph
Add a generic SuperIO ACPI generator, dropping the need to include additional code in DSDT for SuperIO. It generates a device HID based on the decoded I/O range. Tested on Supermicro X11SSH-TF using AST2400. The SSDT contains no errors and all devices are present. Possible TODOs: * Add "enter config" and "exit config" bytes * Generate support methods to enter and exit config mode * Generate support methods to query, change or disable current resource settings on specific LDNs Change-Id: I2716ae0580d68e5d4fcc484cb1648a2cdc1f4ca0 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33033 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de>
