Intel Raptor Lake HX, System76 Adder WS 3 Added To Coreboot

System76 has contributed Intel Core Raptor Lake HX support to Coreboot with some minor additions over the existing Raptor Lake "RPL" code as well as adding their new Adder WS 3 laptop to upstream Coreboot.

System76 recently launched the updated Adder WS laptop with a 13th Gen Intel Core i9 13900HX processor, 15 or 17 inch 1080p display, a choice of NVIDIA GeForce RTX 4050 / 4060 / 4070 graphics, up to 64GB of DDR5-4800 memory, dual M.2 PCIe Gen4 SSD slots, Gigabit Ethernet, and a 4-cell 73Wh battery.

From launch the Adder WS 3 has supported Coreboot while now that code has worked its way into the upstream Coreboot repository.
