Carles Cufi b6109496ff arm: Cortex-M0: Adapt core register code to M0
The Cortex-M0(+) and in general processors that support only the ARMv6-M
instruction set have a reduced set of registers and fields compared to
the ARMv7-M compliant processors.
This change goes through all core registers and disables or removes
everything that is not part of the ARMv6-M architecture when compiling
for Cortex-M0.

Carles Cufi 41bcac3f1c arm: nvic: Fix exception priority access on Cortex-M0(+)
The Cortex-M0(+) and in general processors that support only the ARMv6-M
instruction set can only access the NVIC_IPRn registers with word
accesses, and not with byte ones like the Cortex-M3 and onwards. This
patch addresses the issue by modifying the way that _NvicIrqPrioSet()
writes to the IPRn register, using a word access for Cortex-M0(+).
A similar issue is addressed for internal exceptions, this time for the
SHPR registers that are accessed differently on ARMv6-M.

Reference code taken from CMSIS.

Tomasz Bursztyka a1aa08c288 net: ip: Improve logging by adding a dedicated sys_log level
Let's make net stack having its own level of debugging through sys_log.
It replaces NET_DEBUG by NET_LOG_ENABLED, which is then semantically
better: someone wanting to log the errors might want that not only for
debugging.

Along with it, CONFIG_NET_LOG_GLOBAL option is added, in order to enable
all available logging in network stack. It is disabled by default but
might be found useful when warning/errors need to be logged, so it is
then unnecessary to selectively enable by hand all CONFIG_NET_DEBUG_*
options.

It is possible, locally, to override CONFIG_SYS_LOG_NET_LEVEL by setting
the level one want to NET_SYS_LOG_LEVEL. This can be useful on samples
or tests.

Tomasz Bursztyka 2e95186eff net: nbuf: Let's remove inner type
It's possible to know from which pool the nbuf comes from so
let's reduce nbuf size by removing its internal type attribute which
becomes then useless.

When a data buffer is not coming from nbuf data buffer pool, let's call
it "EXTERNAL", just to make debugging handling a little simple in the
code.

We retain the sys_rand32_get() interface for now on the assumption it

management system.

The existing TEST_RANDOM_GENERATOR related drivers that do not
generate entropy are not modified to expose this driver API since they
cannot generate entropy.

Benjamin Walsh 6209218f40 kernel: optimize ms-to-ticks for certain tick frequencies
Some tick frequencies lend themselves to optimized conversions from ms
to ticks and vice-versa.

- 1000Hz which does not need any conversion
- 500Hz, 250Hz, 125Hz where the division/multiplication are a straight
  shift since they are power-of-two factors of 1000.

In addition, some more generally used values are made to use optimized
conversion equations rather than the generic one that uses 64-bit math,
and often results in calling compiler intrinsics.

These values are: 100Hz, 50Hz, 25Hz, 20Hz, 10Hz, 1Hz (the last one used
in some testing).

Avoiding the 64-bit math intrisics has the additional benefit, in
addition to increased performance, of using a significant lower amount
of stack space: 52 bytes on ARM Cortex-M and 80 bytes on x86.

Only the main thread is available, so a main() function must be

expected, since the main thread cannot pend, it being the only thread in

timeout parameter, effectively polling on the object.

functions can be useful again.

The kernel internals now make use of these APIs instead of the legacy

Benjamin Walsh a2c58d5b85 kernel: fix mis-use of sys_dlist_t vs sys_dnode_t in _timeout
Not a functional bug per-se since they resolve to the same thing, but a
conceptual error nonetheless.

Benjamin Walsh d211a52fc0 kernel: add defines for delta_ticks_from_prev special values
Use _INACTIVE instead of hardcoding -1.

_EXPIRED is defined as -2 and will be used for an improvement so that
interrupts are not locked for a non-deterministic amount of time while
handling expired timeouts.

_abort_timeout/_abort_thread_timeout return _INACTIVE instead of -1 if
the timeout has already been disabled.
