Align Kconfig and Kbuild logic to Linux 4.19 release with minimal impact
on files outside of this scope.
Our previous Kconfig sync was done by commit 5972ff077e ("kconfig /

In this particular re-sync in order to keep clang support working a
number of related changes needed to be pulled in that had been missed

It's a very rare if at all existing occasion when ARC CPU template
is used as is w/o any changes - in the end it's a beauty and competitive
advantage of ARC cores to be tailored for a particular use-case - and
so it doesn't make a lot of sense to offer template-based "-mcpu" selection.
Given for each and every platform we end-up adding quite a few more flags
it's logical to move "-mcpu" selection to platform's definition as well
which we exactly do here.

All of the include/configs/* and defconfig changes in this patch are

and xtensa have been included since these symbols are found in code
under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined
include/configs/* or defconfigs for these architectures exist which
include these symbols.
These results have been confirmed with tools/moveconfig.py.

The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.
This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).
This commit includes a full migration using moveconfig.py to ensure
that each commit compiles. To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.

By default GCC puts global non-initialized variables in COMMON section.
And we used to ignore existence of COMMON section in our linker
scripts though smart LD silently appended it right after .bss.
And the problem here is variables from COMMON section even though
require zeroing in run-time were not zeroed as they were placed
right after __bss_end symbol.
It was a pure luck we never faced serious problem due to this,
but now it is fixed.
Now as for some other architectures we'll just force GCC to put
those global variables in normal .bss section.
This solution is much nicer than adding COMMON section to each and
every linker script.

The DesignWare ARC IoT Development Kit is a versatile platform
that includes the necessary hardware and software to accelerate
software development and debugging of sensor fusion,
voice recognition and face detection designs.
More information is avaialble here [1] and here [2].
The board is based on real silicon with
ARC EM9D-based Data Fusion IP Subsystem.
It sports a rich set of I/O including
* DW USB OTG
* DW MobileStorage (used for micro SD-card)
* GPIO
* multiple serial interface including DW APB UART
* ADC, PWM and eFlash, SRAM and SPI Flash memory
* Real-Time Clock (RTC)
* Bluetooth module with worldwide regulatory compliance
(FCC, IC, CE, ETSI, TELEC)
* On-board 9-axis sensor (gyro, accelerometer and compass)
Extensible with Arduino, Pmod, mikroBUS connectors and a 2x18
extension header.
One of the most interesting features for developers is built-in
Digilent USB JTAG probe so only micro-USB cable is needed!

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.

We used to have the one and only linker script for all ARC boards
and so we relied on a particular order of symbols there.
Because of that we used __ivt_end as the marker of the end of all the
code which won't be true any longer if we move .ivt section to any other
place. That said we'd better check for each section separately.
A couple of other improvements:
1. There's no point to include the marker of section end in interested
range because its address is beyond the section, i.e. we should
compare with "<" but not "<=".
2. .ivt section for ARCv2 cores is just an array of 32-bit ints and
they are not swapped even on little-endia cores while in case of
ARCompact cores .ivt contains valid code so swapping is required.
3. Just in case add check for ARC600 which is also ARCompact
and its .ivt is normal code.
