Yocto master has introduced GCC5 and this doesn't like to compile
the older linux kernels yet. This year it is time to move to a newer
LTS kernel and this can be Linux-4.1. Make space for the upgrade
by moving the recipe to a new name.
In fido the old autoload feature doesn't work anymore and we
need to remove it. Otherwise our sysmobts.service file will
create the /dev/dspl.. /dev/fpgadl... firmware upload files
and we all think that firmware loading is working.
The reverse dependency appears broken. Add a comment to
the recipes to warn us when updating. The issue does not
appear to exist in master of Yocto.

* Disable ext2/ext3 (as ext4 can be used to mount them).
* Enable AUFS/Squshfs support
* Misc improvements (e.g. ARM optimized AES code, disable
drivers/frameworks unlikely to be used)
Jan prefers to store the fully extended .config file so we will
do it. One advantage is to more easily see what has changed between
two kernel versions.

I think the last device we sold was in 2011 and I am not aware
if anyone has used it for the last couple of years. Remove it
to lower the complexity of the builds.
linux-sysmocom_git.bb is used for the BTS, BSC and IDU. Let's
really use 3.10.76 (from 3.10.50 just rebased and not tested
on the device yet). This should fix the Yocto-Master build
tonight.

It seems like the kernel/package/upgrade/... proceess doesn't deal well
with the fact that some options used to be modules, which are now
built-in. Let's keep it as modules for the time being.
this enables conntrack events, ipset, ebtables, tc
scheduler/classifiers/ematches and much more.
it also disables the ATM code for which I don't think we have any use
case.
I edited the config through make menuconfig and then used
savedefconfig but the diff from our config to a minimal
defconfig is too big. So I enabled the temp sensors and i2c
by hand.
Fixes: SYS#1148
Okay "make modules" will lead to the kernel.release file
being re-created. So kernel.bbclass of Yocto master needs
to be fixed.
This reverts commit 3cdbc49cbb.
Somehow the do_shared_workdir tries to access a file that
should be created by do_configure but isn't present then.
Add these items to see what happens during the build.
We want to use backported modules this means we need to make
some thing a module for it to work. Take Daniel's .config file,
run make savedefconfig and update our defconfig.

Go back to have our own do_configure. The kernel.bbclass would
execute "oldnoconfig" where we simply executed "oldconfig". Keep
on using our old way (for the legacy of it). E.g. with the question
how we ended up having SMP enabled in the BSC build this might
be the answer.
OE-Core seems to unpack the kernel sources into another
directory now (e.g. to share the sources with builds for
modules). Use the kernel.bbclass kernel_do_configure and
copy the .config to the build directory.
The kernel is now built in a dedicated build directory.
We actually only use the PMIC (TPS65910) RTC in the hardware,
and not the AM335x RTC. Having a driver for a hardware that doesn't
receive actual backup voltage doesn't make sense.
* split out rtl-nic firmware from the big
linux-firmware package
[hfreyther: For whatever reasons the NIC works without
additional firmware as well. I couldn't see in the driver
source when that is the case and which features are missing]
We want to enable the watchdog in the bootloader already and
for this to be failsafe we need to have a kernel that can boot
and get ethernet without any additional modules. Now systemd
would not be able to trigger the watchdog and the system would
reboot within 60 seconds. I am not sure how the kernel upgrade
will go and we need to try this.
