mb/dell: Add OptiPlex 7020/9020 port
The OptiPlex 7020 and 9020 use physically identical motherboards. WARNING: PWM fan control doesn't work via the EC and the fan runs at a fixed speed. There is likely more EC init to reverse engineer. Each model comes in the following form factors: - 7020: SFF, MT - 9020: USFF (not currently supported), SFF, MT (7020 SFF) Boots Linux and Windows 10: - Tested with an i3-4160 and i5-4460 - DRAM init works using the MRC (4G, 4G+4G) - iGPU init works using libgfxinit (VGA, 2x DP) - PCIe 16x: tested, ok - PCIe 4x: tested, ok - All USB2 and USB3 ports work - SMSC SCH5555 Super I/O: serial works, PS/2 untested - Audio: back and front output works, internal speaker works, mic inputs untested - Ethernet: tested, works (9020 MT) - Tested by Michael Büchler (thanks for the overridetree) Change-Id: Ie7c7089f443aef9890711c4412209bceb1f1e96a Signed-off-by: Mate Kukri <kukri.mate@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/55232 Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nicholas Chin <nic.c3.14@gmail.com>
