mb/foxconn/g41s-k: add new mainboard
Based on the Intel G41 chipset, ICH7 southbridge, and IT8720F Super I/O. Tested, working: * Booting Linux 4.11.3 and Windows 8.1 from USB and HDD * Resume from S3 (Linux and Windows) * Native raminit (DDR2-800) * Native graphics init (SeaBIOS, Linux) * Graphics init with VGA BIOS (SeaBIOS, Windows) * PCI-E x16 PEG slot, PCI-E x1 slot from southbridge * Realtek ALC888 HD Audio (including front panel and jack detection) * Realtek R8168 Gigabit LAN * Both SATA ports * USB 1.1 and 2.0 devices (keyboard, mass storage) * PC speaker beep * COM header * Super I/O Environment controller (temps, voltage, fans) * PS/2 keyboard and mouse * Flashing with `flashrom -p internal` * 1MiB and 2MiB SPI flash chips * CMOS gfx_uma_size Appears, OS driver loads, but otherwise untested: * IrDA header * CIR header * TPM header Untested: * S/PDIF digital audio Tested, known broken: * CMOS power_on_after_fail * USB keyboard in secondary payloads Change-Id: Ifc4c8935b1a11e55f4bf6cfa484a8a8d09b1adda Signed-off-by: Samuel Holland <samuel@sholland.org> Reviewed-on: https://review.coreboot.org/20027 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
