Merge tag 'arc-updates-for-2018.11-rc2' of git://git.denx.de/u-boot-arc

Here we do a couple of impovements for all ARC boards
as well as introduce yet another developemnt board.

1. Now for ARC boards we print CPU and board info
which is useful for users and helps with
analysis of logs "post-mortem".

2. Synopsys IoT development kit support is added
This one might bw a bit too late as we're past RC1
but:
1) This doesn't affect any other arches etc
as we change purely ARC code.
2) I've got a chance to talk about U-Boot on
IoT platforms during ELCE (my proposal was on
a wait list and only this week I've got
an update and invitation to talk) so it would
be good to have this board as a primer in upstream
code-base by the time of ELCE 2018.
3) For complete support of IoT devkit I'm yet to
significantly rework regmap subsystem in U-Boot
but that's a different topic and hopefully it will
be done sometime soon... though not this release
cycle for sure.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

arc: dts: separate single axs10x.dts file

We want to use the same device tree blobs in both Linux and U-Boot for
ARC boards.

Earlier device tree sources in U-Boot were very simplified and hadn't been
updated for quite a long period of time.

So this commit is the first step on the road to unified device tree blobs.

First of all we re-organize device tree sources for AXS10X boards.
As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and
AXC003 cpu tiles respectively we add corresponding device tree source
files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for
cpu tiles and axs101.dts and axs103.dts to represent actual boards.

Also we delete axs10x.dts as it is no longer used.

One more important change - we add timer device to ARC skeleton device
tree sources as both ARC700 and ARCHS cores contain such timer.
We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree
sources as it is referenced via phandle from timer node in common
skeleton.dtsi file.

This replaces legacy arch/arc/lib/timer.c implementation and allows us

may properly inherit Timer's clock from CPU's clock s they really run
synchronously.
