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.

Merge tag 'arc-updates-for-2018.09' of git://git.denx.de/u-boot-arc

Minor changes for ARC

1. Fix CPU clock value in HSDK's .dts so time is counted properly.
2. Enable bootelf command on EMDK

ARC: HSDK: Fix timer frequency value

CPU (and hence cpu timers) on HSDK board runs at 500MHz after
preloader so fix wrong CPU frequency value in hsdk.dts

That's a set of prety minor changes and fixes for ARC.

Among them:
* Improvement in CREG GPIO driver used on ARC dev boards
that allow us to re-use the driver for SPI's chip select

* Enable SPI-flsh on AXS10x boards which allows to update
U-Boot binary that gets loaded by boot-ROM

* Fix accommodating always utilized unaligned access by
GCC for ARC starting from 8.1.0

GPIO: CREG: improve flexibility of hsdk-creg-gpio driver

GPIO: CREG: improve flexibility of hsdk-creg-gpio driver

CREG GPIO is a driver for weird soc-specific output ports, which are
controlled by some fields in memory mapped register.

Example:

31 9 7 5 0 < bit number
| | | | |
[ not used | gpio-1 | gpio-0 | <-shift-> ] < 32 bit register
^ ^
| |
write 0x2 == set output to "1" (activate)
write 0x3 == set output to "0" (deactivate)

As of tooday we only support fixed (hardcoded) bit per gpio line,
activate / deactivatei and shift values. Fix that by read them from
device tree to be able to use this driver for other boards.

Remove "hsdk" prefix from compatible string as this driver can be
used with different boards like HSDK, AXS101, AXS103, etc.

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.

Merge tag 'arc-for-2018.05' of git://git.denx.de/u-boot-arc

More ARC changes and fixes for v2018.05

* Update of ARC tools to the most recent arc-2017.09
* Fix for compile-time warning for AXS10x
* Add support of platform-specific commands for HSDK
* Add support for on-board SPI flash on HSDK
Note though that for write support another series [1]
is required. I hope that Jagan will be able to review and
act on SPI flash improvement series before we get beyond RC1.

Also note that to get clean build for HSDK we need to disable
stack-usage check [2] as our current GCC erroneously tries to calculate
stack-usage on a naked function which leads to warning.

ARC: HSDK: Add platform-specific commands

This patch add support of hsdk platform-specific commands:

hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq
environment variables/command line arguments

hsdk_clock get - save clock frequencies to axi_freq, cpu_freq
and tun_freq environment variables

hsdk_clock print - show CPU, AXI, DDR and TUNNEL current
clock frequencies.

hsdk_clock print_all - show all currently used clock frequencies.

hsdk_init - setup board HW in one of pre-defined configuration
(hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 /
hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4)

hsdk_go - run baremetal application on hsdk configured
by hsdk_init command.

This patch changes default behaviour of 'bootm' command:
now we are able to set number of CPUs to be kicked by setting
'core_mask' environment variable before 'bootm' command run.
