From 78d0256f1d2bb09e4430f2bd56b58df78d54311b Mon Sep 17 00:00:00 2001 From: Marcello Sylvester Bauer Date: Sun, 11 Nov 2018 18:03:26 +0100 Subject: [PATCH] LinuxBoot: refactor payload Clean and refactor the structure of the LinuxBoot payload integration, to make it more modular and readable. The kernel and initramfs should handled in separated makefiles. tested with: - qemu-i440fx (x86, x86_64) - cavium CN8100 (arm64) Change-Id: I41d0275a5f7efb920e881f43b0acda29f41ee221 Signed-off-by: Marcello Sylvester Bauer Reviewed-on: https://review.coreboot.org/c/29581 Tested-by: build bot (Jenkins) Reviewed-by: Philipp Deppenwiese --- payloads/external/LinuxBoot/Kconfig | 55 +++++++++-- payloads/external/LinuxBoot/Makefile | 99 ++++++------------- .../LinuxBoot/arm64/kernel_fdt_lzma.its | 28 +++--- payloads/external/LinuxBoot/targets/linux.mk | 95 ++++++++++++++++++ payloads/external/LinuxBoot/targets/u-root.mk | 19 ++-- payloads/external/Makefile.inc | 22 +++-- 6 files changed, 207 insertions(+), 111 deletions(-) create mode 100644 payloads/external/LinuxBoot/targets/linux.mk diff --git a/payloads/external/LinuxBoot/Kconfig b/payloads/external/LinuxBoot/Kconfig index ba8b5a6d08..046faef287 100644 --- a/payloads/external/LinuxBoot/Kconfig +++ b/payloads/external/LinuxBoot/Kconfig @@ -1,6 +1,7 @@ ## This file is part of the coreboot project. ## ## Copyright (C) 2017 Facebook Inc. +## Copyright (C) 2018 9elements Cyber Security ## ## 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 @@ -16,6 +17,7 @@ if PAYLOAD_LINUXBOOT choice prompt "Architecture" + depends on LINUXBOOT_COMPILE_KERNEL || LINUXBOOT_BUILD_INITRAMFS default LINUXBOOT_X86_64 config LINUXBOOT_X86_64 @@ -42,9 +44,22 @@ endchoice config LINUXBOOT_ARCH string default "amd64" if LINUXBOOT_X86_64 - default "386" if LINUXBOOT_X86 + default "i386" if LINUXBOOT_X86 default "arm64" if LINUXBOOT_ARM64 +comment "Linux kernel" + +config LINUXBOOT_COMPILE_KERNEL + bool "Compile kernel" + default n + +config LINUXBOOT_KERNEL_PATH + string "Path to kernel" + default "Image" + depends on !LINUXBOOT_COMPILE_KERNEL + +if LINUXBOOT_COMPILE_KERNEL + choice prompt "Kernel version" default LINUXBOOT_KERNEL_STABLE @@ -73,19 +88,35 @@ config LINUXBOOT_KERNEL_CONFIGFILE Add your own kernel configuration file.
