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"
