So far we didn't allow CPU private 64-bit RTC timer to register in SMP
as the individual counters may not be synchronized across cores.
However there is a situation when we build SMP kernel but want to use
the same image on UP as well as SMP hardware. Here we would certainly
want to use RTC, but c
* Remove support of the second argument in IDU interrupts (it is
deprecated and not used anymore).
* Remove useless declaration of interrupts list in IDU intc because
it is not used anymore and the kernel can obtain information about
supported interrupts from build registers.

No need for specifying a list of interrupts in the declaration
of IDU interrupt controller anymore since the kernel can obtain
a number of supported interrupts from the build register.
Also delete support of the second parameter for devices which
are connected to IDU because it is not used anywher
Hi Vineet,
I have checked reworked patches. I think it is fine.

Hi Noam,
When we started off with NPS support, it seems dcache was not enabled. Thats why
we introduced ARC_HAS_COH_CACHES etc.
But it seems eznps selects this anyways.
There is no other requirement for this toggle - are you OK if I remove it.

ARC VDK for EVSS uses UIO for communication with Embedded Vision
Subsystem.

ARC VDK virtual platform emulates host MMC controller (DW Mobile Storage)
and moreover rootfs is situated on that virtual card.

In recent VDKs ARC cores are configured as "run on reset"
which made existing kernel configuration outdated to effect that
slave cores never start execution of the code keeping only master
online.
With that fix we're again in sync with VDK platform.
And while at it we regenerate defconfig via sav
This series improves ARC VDK support in upstream Linux kernel by:
1) Removal of UP configuration which is no longer supported by ARC VDK.
Instead SMP platform with all but master cores halted is used to mimic
UP system.
2) Adding off-the-tree patches that enable MMC card and UIO
