From cee930a39b183260ea83ac72fc9ca59d61353d8d Mon Sep 17 00:00:00 2001 From: Tobias Diedrich Date: Sun, 12 Feb 2017 14:09:06 +0100 Subject: lenovo/s230u: Add Thinkpad Twist (S230U) Created using autoport plus some manual work and copying from G505S to account for the non-H8 EC. This model uses the same ENE KB9012 EC as the G505S. Tested: - Mainboard variant with 8GB Elpida DDR3 - SeaBIOS payload - Booting into Linux 4.9.6 with Debian/unstable installed on the internal HDD/SDD slot - Native raminit - Both native VGA init and option rom VGA init - Basic TPM functionality (auto-detection and RNG) - Battery status readout - Basic ACPI functions (power button event; power-off; reboot) - thinkpad-acpi hotkey functions - thinkpad-acpi LED control (red thinkpad LED) - Suspend to RAM and resume works - Mini displayport output works Known issues: - Patches needed for EC battery support https://review.coreboot.org/#/c/18348/ https://review.coreboot.org/#/c/18349/ - No thermal zone since temperature sensing is not H8-compatible and needs to be reverse engineered. Not tested: - msata/wwan (probably works) Signed-off-by: Tobias Diedrich Change-Id: I52bc4515277e5c18afbb14a80a9ac788049f485c Reviewed-on: https://review.coreboot.org/18351 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Rudolph --- src/mainboard/lenovo/s230u/acpi_tables.c | 33 ++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 src/mainboard/lenovo/s230u/acpi_tables.c (limited to 'src/mainboard/lenovo/s230u/acpi_tables.c') diff --git a/src/mainboard/lenovo/s230u/acpi_tables.c b/src/mainboard/lenovo/s230u/acpi_tables.c new file mode 100644 index 0000000000..21fce85f5a --- /dev/null +++ b/src/mainboard/lenovo/s230u/acpi_tables.c @@ -0,0 +1,33 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2007-2009 coresystems GmbH + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; version 2 of the License. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
