Fabien Chereau 49abcb3fff device: add a new macro to obtain the device object symbol name
The new SYS_GET_DEVICE_NAME macro can be used in combination with
SYS_GET_DEVICE to obtain an external reference to a static device
object, e.g.:

extern struct device SYS_GET_DEVICE_NAME(my_device_name);
struct device* dev = SYS_GET_DEVICE(my_device_name);

dev is here set at compile time.

Juan Manuel Cruz b798c0adad devices: _PASTE macro relocated from init.h to common.h
The _PASTE and _PASTE2 macros are relocated from init.h (device handling) to
toolchain/common.h for better reuse.
_PASTE and PASTE_2 macro are renamed to _CONCAT and _DO_CONCAT.
These names are more descriptive.

Dmitriy Korovkin 57f2741e4f init: Implement fine-grained initialization policy
Put initialization priorities as device driver Kconfig
parameter.

Initialization priority value for each platform is defined
in the platform Kconfig file.

Drivers and platform code use SYS_DEFINE_DEVICE to add
and initialization function.

Dirk Brandewie 7a1e221733 init: add SYS_GET_DEVICE() macro to bury &__initconfig_* names usage.
Add a macro to retrieve the device structure for a config structure by
name.  This avoids the very error prone activity of the developer
having to *know* the way the internal object is named.

Allan Stephens a860cb7bff init: Support fine-grained device initialization priorities
Introduces the SYS_DEFINE_DEVICE() macro, which supports 5 distinct
levels of device initialization and 100 priorities within each level.

Note: The existing init macros (e.g. nano_early_init()) have been
adapted to utilize the enhanced initialization model, but will
eventually be retired.

Allan Stephens 7b006066a4 init: Simplify symbol name generated by DECLARE_DEVICE_INIT_CONFIG()
Gets rid of the trailing initialization level character from the
name of the device variable generated by the macro, since it serves
no useful purpose. (The linker scripts place the various initialization
sections in ascending order based on the name of the section, so there
is no need to embed the initialization level in the variable name itself.)

Dirk Brandewie 92d01351aa init: Add more verbose comment block
There has been some confusion around the usage model of the init
system. Add a comment block to hopefully limit the confusion. This
should not be construed to replace the documentation that has yet to
be written for the init subsystem.

Dirk Brandewie 58a534b929 init: add pure_core_init level
There are devices that need are part of the architecture core the need
to be initialized prior to devices that are integrated around a core
to make up a complete SOC. Namely the interrupt controller in the SOC
must be configured in order to allow the integrated IP blocks drivers
to initialize correctly.

Dirk Brandewie a88cd0fc34 init: Split pure_init into pure_init_{early,late} levels
Split the pure init level into two phases this allows for easier
migration of the nano kernel init process without resorting to naming
or link order to force the ordering of functions at pure init
time. The need for change was discovered while moving the system
timers to be initialized by the init system.  The base timer driver
(eg. HPET) must be initialised prior to the system clock being enabled
both of which need to happen before nano-kernel init.

compiler, trailing semi-colons may result in a warning when a user invokes
those macros AND adds their own trailing semi-colon.
