From 472d5111adc037b8ffeeac9ae9362eaa8ec89e45 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 15 Mar 2017 01:25:49 -0500 Subject: google/slippy: clean up NGI and move to libgfxinit - remove old, buggy NGI code from falco/peppy variants - remove superfluous INTEL_DP/INTEL_DDI configs, since already selected by northbridge/haswell - always use libgfxinit when use native init config selected - enable NGI/libgfxinit for all slippy variants The reset of the old Haswell NGI code will be cleaned up in a subsequent patchset. Test: select MAINBOARD_DO_NATIVE_VGA_INIT, observe panel init using SeaBIOS and Tianocore payloads on peppy, wolf variants Change-Id: Id5727cad7f714ffa57e77e2a25505e3c28f55237 Signed-off-by: Matt DeVillier Reviewed-on: https://review.coreboot.org/18824 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber --- src/mainboard/google/slippy/Kconfig | 6 +- .../google/slippy/variants/falco/Makefile.inc | 2 - src/mainboard/google/slippy/variants/falco/gma.c | 246 ------------------- .../google/slippy/variants/falco/i915io.c | 125 ---------- .../variants/falco/include/variant/mainboard.h | 21 -- .../google/slippy/variants/peppy/Makefile.inc | 2 - src/mainboard/google/slippy/variants/peppy/gma.c | 272 --------------------- .../google/slippy/variants/peppy/i915io.c | 139 ----------- .../variants/peppy/include/variant/mainboard.h | 21 -- 9 files changed, 2 insertions(+), 832 deletions(-) delete mode 100644 src/mainboard/google/slippy/variants/falco/gma.c delete mode 100644 src/mainboard/google/slippy/variants/falco/i915io.c delete mode 100644 src/mainboard/google/slippy/variants/falco/include/variant/mainboard.h delete mode 100644 src/mainboard/google/slippy/variants/peppy/gma.c delete mode 100644 src/mainboard/google/slippy/variants/peppy/i915io.c delete mode 100644 src/mainboard/google/slippy/variants/peppy/include/variant/mainboard.h (limited to 'src/mainboard/google/slippy') diff --git a/src/mainboard/google/slippy/Kconfig b/src/mainboard/google/slippy/Kconfig index 1537ff11ca..cfae4e4733 100644 --- a/src/mainboard/google/slippy/Kconfig +++ b/src/mainboard/google/slippy/Kconfig @@ -13,18 +13,16 @@ config BOARD_GOOGLE_BASEBOARD_SLIPPY select HAVE_SMI_HANDLER select MAINBOARD_HAS_CHROMEOS select MAINBOARD_HAS_LPC_TPM - select MAINBOARD_HAS_NATIVE_VGA_INIT if (BOARD_GOOGLE_FALCO || BOARD_GOOGLE_PEPPY) - select INTEL_DP if (BOARD_GOOGLE_FALCO || BOARD_GOOGLE_PEPPY) - select INTEL_DDI if (BOARD_GOOGLE_FALCO || BOARD_GOOGLE_PEPPY) select INTEL_INT15 select MAINBOARD_HAS_LIBGFXINIT + select MAINBOARD_USE_LIBGFXINIT if MAINBOARD_DO_NATIVE_VGA_INIT if BOARD_GOOGLE_BASEBOARD_SLIPPY config VBOOT select EC_GOOGLE_CHROMEEC_SWITCHES select VBOOT_LID_SWITCH - select MAINBOARD_DO_NATIVE_VGA_INIT if (BOARD_GOOGLE_FALCO || BOARD_GOOGLE_PEPPY) + select MAINBOARD_DO_NATIVE_VGA_INIT select VBOOT_VBNV_CMOS config MAINBOARD_DIR diff --git a/src/mainboard/google/slippy/variants/falco/Makefile.inc b/src/mainboard/google/slippy/variants/falco/Makefile.inc index aee33f9188..38d27a4ceb 100644 --- a/src/mainboard/google/slippy/variants/falco/Makefile.inc +++ b/src/mainboard/google/slippy/variants/falco/Makefile.inc @@ -13,8 +13,6 @@ ## GNU General Public License for more details. ## -ramstage-$(CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT) += gma.c i915io.c - ## DIMM SPD for on-board memory SPD_BIN = $(obj)/spd.bin diff --git a/src/mainboard/google/slippy/variants/falco/gma.c b/src/mainboard/google/slippy/variants/falco/gma.c deleted file mode 100644 index 19f467c8de..0000000000 --- a/src/mainboard/google/slippy/variants/falco/gma.c +++ /dev/null @@ -1,246 +0,0 @@ -/* - * This file is part of the coreboot project. - * - * Copyright 2013 Google Inc. - * - * 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.
