adeos-ipipe-* are the previous generation of adeos I-pipe patches, they
stop around Linux version 3.0/3.1.
ipipe-core-* are a new incarnation of the adeos I-pipe patches, they
start at Linux version 3.2. The idea is to make the patch simpler by
making the assumption that Xenomai is the only user of the patch, so cut
down on things that were a bit more generic. At this chance we also did
some other refactoring, such as putting in a common place things that
were the-same-but-not-really on all architectures. What also changed is
that there is now one git branch for all the architectures.
the branch for-ipipe-3.2-arm is a branch in
git://git.xenomai.org/ipipe-gch.git
which is the git I use for working on the I-pipe patch. This branch is
merged in the core-3.2 branch in the official I-pipe git repository at:
git://git.denx.de/ipipe.git
The branch core-3.2 is the branch from which the ipipe-core-3.2-*
patches are made.
In the ipipe-gch git, you can also find the for-core-3.4 branch which
contains the current status of my work on the Adeos I-pipe core patched
Linux 3.4. There is currently no pending issue on this branch (and I
plan to backport some of the changes in the for-ipipe-3.2-arm branch).
But to use that branch, you will need to use the master branch from the
xenomai git:
git://git.xenomai.org/xenomai-2.6.git
