kernel-yocto/linux-yocto-custom: support low bandwidth options
To support configurations where active development is not being done within the oe/bitbake build environment and restricted bandwidth situations, this commit allows the SRC_URI to point to a kernel tgz instead of a full git repository. Outside of the upstream tgz instead of a kernel git repository, the restrictions, config and patch process is the same as any linux-yocto-custom recipe. An example linux-yocto-custom based recipe would have a configuration like this to build the 3.7 kernel, using an externally supplied config, from the 3.7 tgz: SRC_URI = "http://kernel.org/pub/linux/kernel/v3.0/linux-3.7.tar.bz2" PV = "3.7" S = "${WORKDIR}/linux-3.7" SRC_URI[md5sum] = "5323f3faadd051e83af605a63be5ea2e" SRC_URI[sha256sum] = "dc08d87a579fe2918362e6666e503a95a76296419195cb499aa9dd4dbe171a9e" [YOCTO #2686] (From OE-Core rev: 08b3a282ce75a9972694f0c4379179505b9ec91f) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
