[Buildroot] [PATCH v2 1/2] cramfs: change to new site location
Chris Brandt
chris.brandt at renesas.com
Sat Apr 7 12:07:00 UTC 2018
As of Linux-4.15, cramfs now has a official maintainer again.
Additionally, that person is hosting and maintaining a new version of
cramfs-tools.
Patches 0001-endian.patch and 0003-fix-missing-types.patch are no longer
needed because they have been upstreamed.
However, since patch 0002-cygwin_IO.patch is so old, it is being
removed until someone that needs it can reapply and test it. At
that point, they should submit the changes to the new cramfs-tools
maintainer instead of adding the patches back here.
