From 3e4f7a39f8cbdfc7cd097b5c57c43f52d9b0fb4c Mon Sep 17 00:00:00 2001 From: "Jonathan A. Kollasch" Date: Fri, 10 Jan 2020 13:23:02 -0600 Subject: mainboard: add Supermicro X9SCL/X9SCM Boots to Linux. Works: - CPU (Core i3-2120 tested) - Memory (one 1GB 1Rx8 PC3-10600E module tested) - Slots 4, 6, 7 To fix/improve: - SuperIO hardware monitor setup for PECI and fan control - SuperIO ASL in DSDT (e.g. UART Devices) - PEG PCIe lanes (should show x8 max width instead of x16 on 0:1.0 for Slot 7) Untested: - IPMI where BMC is fully implemented (X9SC[LM](+)-F variants) - GbE on X9SCL+-F (where there are two 82574L instead of one) - Slot 5 (x4 on 0:06.0) (only applicable to X9SCM variants) Signed-off-by: Jonathan A.
