superio/common: Add ssdtgen for generic SuperIOs
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>
