There are two aspects to this: CPU registers are twice as big, and the
load and store instructions must use the 'd' suffix instead of the 'w'
one. To abstract register differences, we simply use a ulong_t instead
of u32_t given that RISC-V is either ILP32 or LP64. And the relevant
lw/sw instructions are replaced by LR/SR (load/store register) that get
defined as either lw/sw or ld/sd. Finally a few constants to deal with
register offsets are also provided.

With the upcoming riscv64 support, it is best to use "riscv" as the
subdirectory name and common symbols as riscv32 and riscv64 support
code is almost identical. Then later decide whether 32-bit or 64-bit
compilation is wanted.
Redirects for the web documentation are also included.
Then zephyrbot complained about this:
"
New files added that are not covered in CODEOWNERS:
dts/riscv/microsemi-miv.dtsi
dts/riscv/riscv32-fe310.dtsi
Please add one or more entries in the CODEOWNERS file to cover
those files
"
So I assigned them to those who created them. Feel free to readjust
as necessary.

Add a new sifive,plic-1.0.0 binding that inherits from the riscv,plic0
binding. The new binding adds a required riscv,ndev property, which
gives the number of external interrupts supported.
Use the new binding for microsemi-miv.dtsi (with a value of 31 for
riscv,ndev, from http://www.actel.com/ipdocs/MiV_RV32IMAF_L1_AHB_HB.pdf)
and riscv32-fe310.dtsi (which already assigns riscv,ndev).
Also remove a spurious riscv,ndev assignment from
riscv32-litex-vexriscv.dtsi.
Also make edtlib and the old scripts/dts/ scripts replace '.' in
compatible strings with '_' when generating identifiers.

ARC nSIM simulates pretty much any modern ARC core,
moreover it emulates a lot of different core features so
it is possible to play with them even wo real hardware.
Thus we add yet another ARC core family to be used on simulated
nSIM board.
For now it's just a basic configuration with ARC UART for
smoke-testing of Zephyr on ARC HS CPUs.

The ARC HS is a family of high performance CPUs from Synopsys
capable of running wide range of applications from heavy DPS
calculation to full-scale OS.
Still as with other ARC cores ARC HS might be tailored to
a particular application.
As opposed to EM cores ARC HS cores always have support of unaligned
data access and by default GCC generates such a data layout with
so we have to always enable unaligned data access in runtime otherwise
on attempt to access such data we'd see "Unaligned memory exception".
Note we had to explicitly mention CONFIG_CPU_ARCEM=y in
all current defconfigs as CPU_ARC{EM|HS} are now parts of a
choice so we cannot simply select ether option in board's Kconfig.
And while at it change "-mmpy-option" of ARC EM to "wlh1"
which is the same as previously used "6" but matches
Programmer's Reference Manual (PRM) and is more human-friendly.

Add a kernel timer driver for the MEC1501 32KHz RTOS timer.
This timer is a count down 32-bit counter clocked at a fixed
32768 Hz. It features one-shot, auto-reload, and halt count down
while the Cortex-M is halted by JTAG/SWD. This driver is based
on the new Intel local APIC driver. The driver was tuned for
accuracy at small sleep values. Added a work-around for RTOS
timer restart issue. RTOS timer driver requires board ticks per
second to be 32768 if tickless operation is configured.
