* add arc mpu driver
* modify the corresponding kconfig and kbuild
* currently only em_starterkit 2.2's em7d configuration
has mpu feature (mpu version 2)
* as the minimum region size of arc mpu version 2 is 2048 bytes and
region size should be power of 2, the stack size of threads
(including main thread and idle thread) should be at least
2048 bytes and power of 2
* for mpu stack guard feature, a stack guard region of 2048 bytes
is generated. This brings more memory footprint
* For arc mpu version 3, the minimum region size is 32 bytes.
* the codes are tested by the mpu_stack_guard_test and stackprot

Stop using CONFIG_I2C_x_DEFAULT_CFG to get the initial value. Since we
only support master mode we always default to it for initial config and
we get the bitrate from the device tree.

Add cross-referenced information on the 96b_carbon and
96b_carbon_nrf51 pages which disambiguates between the two "boards".
Also describe how to flash 96b_carbon_nrf51 with
samples/bluetooth/hci_spi and 96b_carbon with samples/bluetooth/ipsp
to support a Bluetooth HCI stack on 96Boards Carbon (the physical
board).
While we're here, make the documentation page for 96b_carbon match the
format in doc/templates/board.tmpl.

On 96Boards Carbon, Bluetooth is provided by a secondary nRF51 chip
connected to SPI_1, so enable this peripheral and its driver when BT
is selected.
Similarly, provide BT_SPI_* configs to integrate with the BT HCI SPI
driver. The files these config values apply to only get built when
CONFIG_BT=y, but this configuration can't be handled in the "if BT"
section in 96b_carbon's Kconfig.defconfig. This is because BT_SPI is
a choice value, and thus doesn't support a default setting.

Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."
Effectively, the CC3220 SOC replaces the CC3200.
This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.
Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.

The SimpleLink host driver comes with its own definition of
__errno, which conflicts with Zephyr's definition, but has
a mechanism to enable use of the porting OS's __errno variable.
This patch enables SimpleLink to use Zephyr's __errno
via the DPL porting layer.

The ESP-WROOM-32 board exits the bootloader at 40 MHz, not 160 MHz as
suggested by documentation. The CCOUNT special register works as
advertised, but not at the expected rate. This was verified by
timestamping (at the host) the output of a dependency-free loop that
looks like:
int key = irq_lock();
while(1) {
u32_t i, count;
volatile int dummy;
for(i = 0; i < 5000000; i++) {
dummy++;
}
__asm__ volatile ("rsr.ccount %0" : "=a"(count));
printk("%d\n", count);
}
The SoC has a fairly robust set of possible CPU clocking modes, but we
don't have a driver for that yet. Until we do, set the single
configured CPU frequency to the one we get at runtime.

The Xtensa port was the only one remaining to be converted to the new
way of connecting interrupts in Zephyr. Some things are still
unconverted, mainly the exception table, and this will be performed
another time.
Of note: _irq_priority_set() isn't called on _ARCH_IRQ_CONNECT(), since
IRQs can't change priority on Xtensa: while the architecture has the
concept of interrupt priority levels, each line has a fixed level and
can't be changed.

The random number generator from ESP32 uses noise from Wi-Fi and
Bluetooth radios. If these are off, a pseudo-random number is
generated instead; this is currently the case, but even though it's a
black box, it's arguably better than returning a timestamp as a
pseudo-random number generator.
According to the ESP32 Technical Reference manual, the RNG passed the
Dieharder Random Number Test suite (version 3.31.1)[1], but nothing has
been said about the quality of the PRNG.
The RNG register is read directly; no effort is made to use its
contents to feed an entropy pool in a way that's similar to /dev/random
on POSIX systems, as no such subsystem exists on Zephyr at the moment.

The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

ReST defines interpreted text roles where text enclosed by single quotes
can be "intrepreted", for example :ref:`some name` becomes a link to
a label anywhere in the doc set named "some name", :c:func:`funcname()`
becomes a link to the API documentation for "funcname", and
:option:`CONFIG_NAME` becomes a link to, in our case, the documentation
for the generated Kconfig option.
This patch fixes uses of `some name` (without a role) by either adding
an explicit role, or changing to ``some name``, which indicates inline
code block formatting (most likely what was intended).
This is a precursor to changing the default behavior of interpreted
text to treat `some name` as :any:`some name` (as configured in
doc/conf.py), which would attempt to create a link to any available
definition of "some name".
We may not change this default role behavior, but it becomes an option
after the fixes in this patch. In any case, this patch fixes incorrect
uses of single-quoted text (possibly introduced because GitHub's
markdown language uses single-quoted text for inline code formatting).

This change fixes the prescaler values in the defconfig. The prescaler
values shown in the technical reference manual (STM32F407xx, p.19)
differ from those in the defconfig which results in wrong timer delays.
This patch corrects those values according to the manual. I tested it by
toggling a GPIO pin with different timer frequencies and run the
sanitycheck.
