From: Ulf Samuelsson Date: Fri, 24 Aug 2007 05:36:46 +0000 (-0000) Subject: This patch allows each project to have a private linux build. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=60eb97a42fe0cf8ebad55a6213e2399b4201e3ec;p=buildroot.git This patch allows each project to have a private linux build. Split build of kernel headers and kernel image into two source trees. Kernel headers are built in $(TOOL_BUILD_DIR) Kernel build is in $(PROJECT_BUILD_DIR) Make sure that kernel patches are applied to the kernel tree in $(PROJECT_BUILD_DIR) Add board specific patches, if available. --- diff --git a/target/linux/Makefile.in b/target/linux/Makefile.in index e83bfd53ce..948dd3ea26 100644 --- a/target/linux/Makefile.in +++ b/target/linux/Makefile.in @@ -6,48 +6,53 @@ ifneq ($(filter $(TARGETS),linux26),) +ifeq ($(DOWNLOAD_LINUX26_VERSION),) +# User did not define linux version, try using headers ifeq ($(LINUX_HEADERS_VERSION),) -# Version of Linux to download and then apply patches to -# XXX: andersee, i do not understand why we need this (BF) -DOWNLOAD_LINUX26_VERSION=2.6.19.2 +# We did not have headers (this is for real???) +# Version of linuc before patches +DOWNLOAD_LINUX26_VERSION=2.6.22.1 # Version of Linux after applying any patches -LINUX26_VERSION=2.6.19.2 +LINUX26_VERSION=2.6.22.1 else +# OK, we have headers, use them...
