[yocto] downloads.yoctoproject.org/mirror out of date

[Georg Lutz]

Hi,

yesterday I had a build error in the unpack step. git couldn't find a 
reference.

It turned out that because of a temporary firewall issue bitbake took 
the http mirror downloads.yoctoproject.org for yocto-kernel-cache.

It looks like the mirror hasn't been updated since a while (Nov last 
year):

$ git ls-remote https://git.yoctoproject.org/git/yocto-kernel-cache 
master
789605826bbbdd4d0762d9e4262d0ef28663770d	refs/heads/master

$ wget -q 
http://downloads.yoctoproject.org/mirror/sources/git2_git.yoctoproject.org.yocto-kernel-cache.tar.gz
$ tar -xzf git2_git.yoctoproject.org.yocto-kernel-cache.tar.gz
$ git log -1
