[OpenWrt-Devel,RFT] arc770: bump kernel to 5.4

Update config with make kernel_oldconfig and copy patch.

Directly switch to kernel 5.4.

I just stupidly copied/refreshed the patch and the config.

Build-tested, run-test required as I have no hardware.

Hi Evgeniy and Alexey,

Could you please test, if this patch works?

We would like to get all targets to kernel 5.4 for the next release and
this is one of the targets still at an older kernel. Adrian and I do not
have any hardware to test this.

You can find this patch also on patchwork:

just looked at this one again. This target appears to be upstream with almost no local adjustments.

I wonder whether I should just push the kernel bump to master if it builds fine, without a device test. (would do a new refresh and build-test beforehand, of course). Nobody seems to care anyway.

Do you have an opinion here?

I am fine with this.

I think we do not have many users on this target anyway.

@Evgeniy and @Alexey: Could you please test if this update to kernel 5.4
for the arc770 works basically.

If someone else has this hardware and can try this out, some feedback
would be nice.

Thank you a lot for updating kernel to 5.4 for arc770! Unfortunately we do not have access to boards with arc770,
so we are not able to test the image right now. By the way we ran Linux kernel v5.4(built by buildroot)
 on arc770 board and it worked well. I guess we can apply this patch and if any issue appears we will fix it.

Thanks and best regards,
Evgeniy Didin

Just tried to build it based on recent master and with buildbot settings, ended with this error, though:

I've found that the root cause is openvswitch selecting libunwind, and due to some mechanism I don't understand openvswitch isn't built anymore for 4.14 on buildbots already (though only for the most recent 4.14.x kernel version).

Since everything else is working, I decided to push 5.4 support now and will be curious whether buildbots run through or not.
