[ Upstream commit 61231eb8113ce47991f35024f9c20810b37996bf ]
"gmac" node stands for just an ordinary Ethernet controller,
which is by no means a provider of interrupts, i.e. it doesn't serve
as an interrupt controller, thus "#interrupt-cells" property doesn't
belong to it and so we remove it.
Fixes:

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:

If you run 'make uImage uImage.gz' with the parallel option, uImage.gz
will be created by two threads simultaneously.
This is because arch/arc/Makefile does not specify the dependency
between uImage and uImage.gz. Hence, GNU Make assumes they can be
built in parallel. One thread descends into arch/arc/boot/ to create
uImage, and another to create uImage.gz.
Please notice the same log is displayed twice in the following steps:
$ export CROSS_COMPILE=<your-arc-compiler-prefix>

This is a race between the two threads trying to write to the same file
arch/arc/boot/uImage.gz. This is a potential problem that can generate
a broken file.
I fixed a similar problem for ARM by commit 3939f33450 ("ARM: 8418/1:
add boot image dependencies to not generate invalid images").
I highly recommend to avoid such build rules that cause a race condition.
Move the uImage rule to arch/arc/Makefile.
Another strangeness is that arch/arc/boot/Makefile compares the
timestamps between $(obj)/uImage and $(obj)/uImage.*:
$(obj)/uImage: $(obj)/uImage.$(suffix-y)
@ln -sf $(notdir $<) $@
@echo ' Image $@ is ready'
This does not work as expected since $(obj)/uImage is a symlink.
The symlink should be created in a phony target rule.
I used $(kecho) instead of echo to suppress the message
'Image arch/arc/boot/uImage is ready' when the -s option is given.

HSDK board has Micrel KSZ9031, recent commit
bcf3440c6d ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY")
caused a breakdown of Ethernet.
Using 'phy-mode = "rgmii"' is not correct because accodring RGMII
specification it is necessary to have delay on RX (PHY to MAX)
which is not generated in case of "rgmii".
Using "rgmii-id" adds necessary delay and solves the issue.

Starting from nSIM 2019.06 is possible to use DW UART
instead of ARC UART. That allows us to merge
"nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp"
with minor changes which were done in previous commits.
We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig
and leave haps_hs_defconfig and haps_hs_smp_defconfig
which can be used on HAPS / nSIM / ZEBU / QEMU platforms
without additional changes in Linux kernel.
For nSIM we should now use UART property values
"-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000"
instead of previously used
"-prop=nsim_mem-dev=uart0,base=0xc0fc1000"

We want to use DW AXI DMAC on HSDK board in our automated verification
to test cache & dma kernel code changes. This is perfect candidate
as we don't depend on any external peripherals like MMC card / USB
storage / etc.
To increase test coverage we want to test both options:
* DW AXI DMAC is connected through IOC port & dma direct ops used
* DW AXI DMAC is connected to DDR port & dma noncoherent ops used
Introduce 'arc_hsdk_axi_dmac_coherent' global variable which can be
modified by debugger (same way as we patch 'ioc_enable') to switch
between these options without recompiling the kernel.
Depend on this value we tweak memory bridge configuration and
"dma-coherent" DTS property of DW AXI DMAC.

As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO
peripherals support for the platform we're going to use.
For now we add 5 Virtio slots in .dts and enable block and network devices
via Virtio-MMIO.
Note even though typically Virtio register set fits in 0x200 bytes
we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size
and so remapping of that area is done clearly.
We also enable DEVTMPFS automount for more convenient use
of external root file-stystem. Before that we used to use built-in
Initramfs which didn't automount DEVTMPFS anyways so we didn't need
that option, while now it starts making sense.

With that change in place use might set desired MAC in U-Boot
with "setenv ethaddr 11:22:33:44:55:66", save environment and
then from boot to boot the same MAC will be used by the kernel.

files but are never automatically deleted.
.PRECIOUS
When make is interrupted during execution, it may delete the target
file it is updating if the file was modified since make started.
If you mark the file as precious, make will never delete the file
if interrupted.
Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.
The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.
Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.
.PRECIOUS: $(obj)/%.lex.c
works, but
.SECONDARY: $(obj)/%.lex.c
has no effect. However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.
The targets specified as .SECONDARY must be explicit. $(targets)
contains all targets that need to include .*.cmd files. So, the
intermediates you want to keep are mostly in there. Therefore, mark
$(targets) as .SECONDARY. It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.
I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

Using compatible strings without the <manufacturer> part for at24 is
deprecated since commit 6da28acf74 ("dt-bindings: at24: consistently
document the compatible property"). Use a correct 'atmel,<model>'
value.

It's very convenient to have fatal signals enabled on developemnt
platform as this allows to catch problems that happen early in
user-space (like crashing init or dynamic loader).
Otherwise we may either enable it later from alive taregt console
by "echo 1 > /proc/sys/kernel/print-fatal-signals" but:
1. We might be unfortunate enough to not reach working console
2. Forget to enable fatal signals and miss something interesting
Given we're talking about development platforms here it shouldn't
be a problem if a bit more data gets printed to debug console.
Moreover this makes behavior of all our dev platforms predictable
as today some platforms already have it enabled and some don't -
which is way too inconvenient.

Set initial core pll output frequency specified in device tree to
100MHz for SMP configuration and 90MHz for UP configuration.
It will be applied at the core pll driver probing.
