From 6308e0e92f624cb18a875ed04e41e1d15fc91054 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Tue, 27 Mar 2018 16:06:34 +0200 Subject: mb/hp: Add new port compaq_8200_elite_sff Add new port based on autoport. The board uses a NPCD378 SuperIO, that is full of custom hardware. The 8MiB flash SOIC-8 can be accessed after cutting of a part of the DIMM slot holder. The flash IC has no diode, powering a part of the board while flashing externaly, including the Standby-LED. The following have been tested and is working: * Native raminit with up to four DIMMs * Libgfxinit on DisplayPort * USB * EHCI debug * Serial on RS232 * Ethernet * PCIe on x4 * PCIe on x16 * SATA * Booting GNU Linux 4.14 using SeaBIOS 1.11.1 as payload * Flashing internaly * PS/2 is working Untested: * PCI slot * LPT port * VBIOS * S3 resume Not working: * PSU fan managment (runs at 100%) * Half of SuperIO functionality is unknown TODO: * Reverse engineer remaining SuperIO registers * Reverse engineer SMM Fixes on follow-up commits: * Added PSU fan control * Reverse engineered some of Super IO's HWM registers * Added SMBIOS tables for IPMI Change-Id: I4ee8da6349222fda8b6c30a7210ffdd65c183439 Signed-off-by: Patrick Rudolph Reviewed-on: https://review.coreboot.org/25385 Reviewed-by: Arthur Heymans Reviewed-by: Paul Menzel Tested-by: build bot (Jenkins) --- src/mainboard/hp/compaq_8200_elite_sff/cmos.default | 6 ++++++ 1 file changed, 6 insertions(+) create mode 100644 src/mainboard/hp/compaq_8200_elite_sff/cmos.default (limited to 'src/mainboard/hp/compaq_8200_elite_sff/cmos.default') diff --git a/src/mainboard/hp/compaq_8200_elite_sff/cmos.default b/src/mainboard/hp/compaq_8200_elite_sff/cmos.default new file mode 100644 index 0000000000..390d231fb1 --- /dev/null +++ b/src/mainboard/hp/compaq_8200_elite_sff/cmos.default @@ -0,0 +1,6 @@ +boot_option=Fallback +debug_level=Spew +power_on_after_fail=Enable +nmi=Enable +sata_mode=AHCI +gfx_uma_size=32M -- cgit v1.2.3
