Patch merged into coreboot/master: x86 chipsets: Link non-code flow CHIPSET_BOOTBLOCK_INCLUDE files
by gerrit＠coreboot.org 30 Dec '15

30 Dec '15

the following patch was just integrated into master: commit 8a13743569a8d1ac61b8a52d2dab621ff4041de2 Author: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> Date: Mon Oct 5 08:00:51 2015 -0700 x86 chipsets: Link non-code flow CHIPSET_BOOTBLOCK_INCLUDE files Non-code flow assembly stubs do not have to be included in bootblock.S, now that we have more freedom in bootblock linking. Rather than bringing these stubs to the config system, just link them in the bootblock. Note that we cannot fully remove CHIPSET_BOOTBLOCK_INCLUDE at this point, as some intel SOCs use this stub for code flow. objdump -h build/cbfs/fallback/bootblock.debug on a few random boards confirms that the appropriate sections are still included in the final binary.

Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/11306 -gerrit commit e0883661053a8d764d7d2f005e3c485e0898025d Author: Damien Zammit <damien(a)zamaudio.com> Date: Wed Aug 19 15:23:32 2015 +1000 gigabyte/ga-g41m-es2l: Add mainboard Board uses x4x native raminit Board boots into Debian 8 with full graphics IRQ9: nobody cared, gets disabled (PIC needs IRQ settings?) VGA: - VGA native init works in grub with analog connector - Fails to boot with both channels of ram populated Change-Id: I7417813456817529b8cbaace45cefe47467d0a82 Signed-off-by: Damien Zammit <damien(a)zamaudio.com> --- src/mainboard/gigabyte/ga-g41m-es2l/Kconfig | 43 ++++++ src/mainboard/gigabyte/ga-g41m-es2l/Kconfig.name | 2 + src/mainboard/gigabyte/ga-g41m-es2l/Makefile.inc | 1 + src/mainboard/gigabyte/ga-g41m-es2l/acpi/ec.asl | 1 + .../gigabyte/ga-g41m-es2l/acpi/ich7_pci_irqs.asl | 34 +++++ .../gigabyte/ga-g41m-es2l/acpi/platform.asl | 28 ++++ .../gigabyte/ga-g41m-es2l/acpi/superio.asl | 1 + .../gigabyte/ga-g41m-es2l/acpi/x4x_pci_irqs.asl | 66 +++++++++ src/mainboard/gigabyte/ga-g41m-es2l/acpi_tables.c | 42 ++++++ src/mainboard/gigabyte/ga-g41m-es2l/board_info.txt | 5 + src/mainboard/gigabyte/ga-g41m-es2l/cstates.c | 37 +++++ src/mainboard/gigabyte/ga-g41m-es2l/devicetree.cb | 150 +++++++++++++++++++ src/mainboard/gigabyte/ga-g41m-es2l/dsdt.asl | 43 ++++++ src/mainboard/gigabyte/ga-g41m-es2l/hda_verb.c | 8 + src/mainboard/gigabyte/ga-g41m-es2l/romstage.c | 163 +++++++++++++++++++++ 15 files changed, 624 insertions(+) diff --git a/src/mainboard/gigabyte/ga-g41m-es2l/Kconfig b/src/mainboard/gigabyte/ga-g41m-es2l/Kconfig new file mode 100644 index 0000000..1892b37 --- /dev/null +++ b/src/mainboard/gigabyte/ga-g41m-es2l/Kconfig @@ -0,0 +1,43 @@ +# +# This file is part of the coreboot project. +# +# Copyright (C) 2015 Damien Zammit <damien(a)zamaudio.com> +# +# 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.
