Merge tag 'arc-last-minute-for-2019.04' of git://git.denx.de/u-boot-arc

This is last minute change which fixes problems in runtime on
AXS10x board caused by some changes in NAND framework and
tiny documentation improvement.

Anyways NAND flash storage was never really used on the board for various
reasons and now we decided to drop it for good.

Note this change only touches 1 ARC board so that should be safe for others.
As usual - build tested in TravisCI, see

ARC: AXS10x: drop NAND support

On AXS10x boards we have non-standard NAND controller
which was never really used a lot as there're other much more
convenient [as they are standard & removable] persistent media
like SD-card and USB mass storage.

Moreover after recent changes we face with some NAND controller
runtime issues. So instead of keeping support of yet another
non-standard peripheral we're dropping its support for good.

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: Rename AXS101 board to more generic AXS10x

As of now we have 2 flavors of ARC SDP boards:
1) AXS101 - with ARC770 in ASIC
2) AXS103 - with ARC HS38 in FPGA

Both options share exactly the same base-board and only differ with
CPU-tiles in use. That means all peripherals are the same (they are
implemented in FPGA on the base-board) and so generic board could be
used for both.

While at it:
* Recreated defconfigs with savedefconfig
* In include/configs/axs10x.h numerical sizes replaced with
defines from linux/sizes.h for better readability.
