From 461bfab7b7e47fd0a76bf6076a438af1b7e2184a Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Mon, 8 May 2017 19:06:22 +0200 Subject: [PATCH 016/198] coreboot: Split parts that are platform-independent. We currently assume that coreboot is always i386, it's no longer the case, so split i386-coreboot parts from generic coreboot code. --- grub-core/Makefile.am | 2 +- grub-core/Makefile.core.def | 6 +- grub-core/commands/i386/coreboot/cb_timestamps.c | 2 +- grub-core/commands/i386/coreboot/cbls.c | 2 +- grub-core/kern/coreboot/cbtable.c | 70 ++++++++++++++++++++++++ grub-core/kern/{i386 => }/coreboot/mmap.c | 6 +- grub-core/kern/i386/coreboot/cbtable.c | 53 +++--------------- grub-core/term/i386/coreboot/cbmemc.c | 2 +- grub-core/video/{i386 => }/coreboot/cbfb.c | 2 +- include/grub/{i386 => }/coreboot/lbio.h | 9 +++ 10 files changed, 99 insertions(+), 55 deletions(-) create mode 100644 grub-core/kern/coreboot/cbtable.c rename grub-core/kern/{i386 => }/coreboot/mmap.c (97%) rename grub-core/video/{i386 => }/coreboot/cbfb.c (99%) rename include/grub/{i386 => }/coreboot/lbio.h (93%) diff --git a/grub-core/Makefile.am b/grub-core/Makefile.am index 809a8aa26..781d0ffbf 100644 --- a/grub-core/Makefile.am +++ b/grub-core/Makefile.am @@ -112,7 +112,7 @@ endif if COND_i386_coreboot KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/i386/tsc.h -KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/i386/coreboot/lbio.h +KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/coreboot/lbio.h KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/video.h KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/video_fb.h KERNEL_HEADER_FILES += $(top_srcdir)/include/grub/gfxterm.h diff --git a/grub-core/Makefile.core.def b/grub-core/Makefile.core.def index fb59a7b1d..45ed0fa6b 100644 --- a/grub-core/Makefile.core.def +++ b/grub-core/Makefile.core.def @@ -166,7 +166,7 @@ kernel = { i386_multiboot = kern/i386/coreboot/init.c; i386_qemu = kern/i386/qemu/init.c; i386_coreboot_multiboot_qemu = term/i386/pc/vga_text.c; - i386_coreboot = video/i386/coreboot/cbfb.c; + i386_coreboot = video/coreboot/cbfb.c; efi = disk/efi/efidisk.c; efi = kern/efi/efi.c; @@ -227,8 +227,9 @@ kernel = { i386_qemu = kern/vga_init.c; i386_qemu = kern/i386/qemu/mmap.c; - i386_coreboot = kern/i386/coreboot/mmap.c; + i386_coreboot = kern/coreboot/mmap.c; i386_coreboot = kern/i386/coreboot/cbtable.c; + i386_coreboot = kern/coreboot/cbtable.c; i386_multiboot = kern/i386/multiboot_mmap.c; @@ -643,6 +644,7 @@ module = { module = { name = cbtable; common = kern/i386/coreboot/cbtable.c; + common = kern/coreboot/cbtable.c; enable = i386_pc; enable = i386_efi; enable = i386_qemu; diff --git a/grub-core/commands/i386/coreboot/cb_timestamps.c b/grub-core/commands/i386/coreboot/cb_timestamps.c index e72f38d6e..e97ea6bed 100644 --- a/grub-core/commands/i386/coreboot/cb_timestamps.c +++ b/grub-core/commands/i386/coreboot/cb_timestamps.c @@ -20,7 +20,7 @@ #include #include #include -#include +#include #include GRUB_MOD_LICENSE ("GPLv3+"); diff --git a/grub-core/commands/i386/coreboot/cbls.c b/grub-core/commands/i386/coreboot/cbls.c index e0a10596f..102291f42 100644 --- a/grub-core/commands/i386/coreboot/cbls.c +++ b/grub-core/commands/i386/coreboot/cbls.c @@ -20,7 +20,7 @@ #include #include #include -#include +#include #include GRUB_MOD_LICENSE ("GPLv3+"); diff --git a/grub-core/kern/coreboot/cbtable.c b/grub-core/kern/coreboot/cbtable.c new file mode 100644 index 000000000..996d3f407 --- /dev/null +++ b/grub-core/kern/coreboot/cbtable.c @@ -0,0 +1,70 @@ +/* + * GRUB -- GRand Unified Bootloader + * Copyright (C) 2007,2008,2013 Free Software Foundation, Inc. + * + * GRUB 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, either version 3 of the License, or + * (at your option) any later version. + * + * GRUB 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.
