Upstreaming effort
Bootlin maintains a number of branches reflecting the in-progress upstream work. They are based on 4.14.y. Those branches are available in the public Git repository at https://github.com/MISL-EBU-System-SW/mainline-public. The logic is as follows:
devel-4.14/<topic>
are topic branches for work in progress, not yet merged upstream. Such branches are based onbackport-4.14
(there are exceptions), and are rebased as neededdevel-4.14/all
which is a branch resulting of the merge of all thedevel-4.14/<topic>
branches
These branches are:
backport-4.14
is based on v4.14.22, with patches backported from upstream, i.e patches that had already been accepted. This branch is not rebased.devel-4.14/comphy
contains fixes and improvements for the comphy.devel-4.14/ppv2
contains fixes and improvements in the mvpp2 network driver.devel-4.14/crypto
contains fixes and optimizations for the Inside Secure SafeXel cryptographic engine which can be found on Marvell 7k/8k and 3720 SoCs.devel-4.14/pcie
contains improvements for compatibility with PCI devices with aardvark (PCIE host controller on Armada 3700).devel-4.14/dt64
contains all the ARM64 Device Tree updates. They are regrouped in a single topic branches to avoid conflicts.devel-4.14/defconfig64
contains the ARM64 defconfig specific patches.devel-4.14/custom-defconfig64
contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based ondevel-4.14/defconfig64
.
Commands used to generate the devel-4.14/all
branch (so that topic branches are always merged in the same order) :
git reset --hard backport-4.14 git merge devel-4.14/comphy devel-4.14/ppv2 devel-4.14/crypto devel-4.14/pcie devel-4.14/dt64 devel-4.14/defconfig64 devel-4.14/custom-defconfig64
