LPC devices. Among other things, the LPC serial ports now appear as ACPI devices. - Move the info for the top-level PCI bus into the PCI emulation code and add ResourceProducer entries for the memory ranges decoded by the bus for memory BARs. - Add a framework to allow each PCI emulation driver to optionally write an entry into the DSDT under the \_SB_.PCI0 namespace. The LPC driver uses this to write a node for the LPC bus (\_SB_.PCI0.ISA). - Add a linker set to allow any LPC devices to write entries into the DSDT below the LPC node. - Move the existing DSDT block for the RTC to the RTC driver. - Add DSDT nodes for the AT PIC, the 8254 ISA timer, and the LPC UART devices. - Add a "SuperIO" device under the LPC node to claim "system resources" aling with a linker set to allow various drivers to add IO or memory ranges that should be claimed as a system resource. - Add system resource entries for the extended RTC IO range, the registers used for ACPI power management, the ELCR, PCI interrupt routing register, and post data register. - Add various helper routines for generating DSDT entries.
