Benjamin Walsh c4a093a24e arm: rework _ScbSystemReset() into sys_arch_reboot()
Rename the function and allow it to handle the 'type'
argument, which is ignored in this case.

Benjamin Walsh 2ace19ede8 arm: allow accessing GPRs in ESF by their real name
The ESF was built using the 'alias' names of the GPRs (a1, lr, pc, etc)
rather than their 'real' name (rN).

Benjamin Walsh 85138855f0 arm: add macro for defining GPRs with aliases
On ARM, GPRs are often known by two names. E.g. the stack pointer is
both 'sp' and 'r13', the first parameter to a function 'a1' and 'r0',
etc. This macro allows defining them in a data structure, e.g. in the
ESF,  without having to create a union, use the correct type, etc: it is
less error-prone and makes for shorter code.

	sys_define_gpr_with_alias(name1, name2)

Benjamin Walsh 4465cf47e9 arm/reset: relocate the vector table when a non-XIP image
The processor is made aware that the vector table built in the image is
located at the start of SRAM in the case of a non-XIP image, rather than
at 0 in as is the case in XIP images.

Benjamin Walsh 21628d41d0 arm: add support for linking images entirely in SRAM
The image will be linked at a different address and with different
ROM/RAM sizes to allow running a bootloder image that loads a payload
image. The addresses/sizes depend on if it is a XIP image or not
(CONFIG_XIP), and in the case of a XIP image, if it is a bootloader
image (CONFIG_IS_BOOTLOADER) or not.

In the case of a bootloader, it is given the full ROM and
CONFIG_BOOTLOADER_SRAM_SIZE kB of SRAM.  When not a XIP image, it is given
the full SRAM minus CONFIG_BOOTLOADER_SRAM_SIZE kB, and is linked at the
start of SRAM.

Andre Guedes 93831ebcce i2c: Fix i2c_qmsi_configure()
In the initial version of the I2C shim driver, the i2c clock gate was
enabled within i2c_qmsi_configure(). After some review rounds we decided
to move it to i2c_qmsi_init() but missed to remove the clk_periph_disable
call within i2c_qmsi_configure(). So this patch removes it.

Benjamin Walsh 2858cbf829 idle: fix tasks waiting when NANO_TIMEOUTS is enabled
Fix an issue where, if a task is pending on a nano timeout, the duration
it wants to wait is not taken into account by the tickless idle code.
This could cause a system to wait forever, or to the limit of the timer
hardware (which is forever, for all intents and purposes).

This fix is to add one field in the nanokernel data structure for one
task to record the amount of ticks it will wait on a nano timeout. Only
one task has to be able to record this information, since, these waits
being looping busy waits, the task of highest priority is the only task
that can be actively waiting with a nano timeout. If a task of lower
priority was previously waiting, and a new task is now waiting, it means
that the wait of the original task has been interrupted, which will
cause said task to run the busy loop on the object again when it gets
scheduled, and the number of ticks it wants to wait has to be recomputed
and recorded again.

Tomasz Bursztyka 930bb9d3ca cc2520: Make the driver more in line with Zephyr
CC2520 drivers as a singleton:
Current driver can only handle a single instance. This is due to the
gpio callback which cannot provide the concerned device (not the gpio
device, the cc2520 one). Setting a singleton instance for now, as the
network stack cannot handle more net devices anyway. This will be fixed
in the future.
In the mean time: improving a bit the usage of spi and gpio by accessing
the cc2520 instance directly.

Also: simplifying SPI usage, useless internal locking removed, better
debugging routines, better busy wait macro and use Zephyr's BIT() macro
instead of internal one.

Jesus Sanchez-Palencia 6504b7e72a gpio: Add QMSI-based implementation
Introduce the GPIO QMSI-based implementation. This is basically a
shim layer that implement's Zephyr's GPIO APIs on top of QMSI drivers.

This is an alternative driver that conflicts with the previous
GPIO_DW implementation. In order to enable it you must set:
- CONFIG_GPIO=n
- CONFIG_GPIO_QMSI=y
- CONFIG_GPIO_0=y
- CONFIG_QMSI_DRIVERS=y
- CONFIG_QMSI_INTALL_PATH="PATH_TO_QMSI"

Note that this driver currently only supports one controller instance,
GPIO_0. It is implemented this way due to a limitation from the current
version of QMSI. QMSI versions later than 1.0 doesn't have this
limitation.

Missing:
- support multiple controller instances (gpio_0, gpio_1, etc);
- enable level triggered interrupts in sync with system clock,
through setting INT_CLOCK_SYNC properly.

Juan Manuel Cruz 41771e5b1c adc: Repetitive buffer management
This commit changes the behavior of the driver when it reports
buffer results back through the callback.

Originally, the driver reported a callback after each sequence
table round signaled by an interrupt. If in repetitive mode,
each reported result was put in the next buffer element,
which was considered circular, and reported back with callback.

Now the behavior changes. If in repetitive mode, each sequence table
round reported by an interruption puts the data  in next element of
the reception buffer. The callback reports back once the buffer is
fulled and stops the sampling process.
