This adds a delayed version of nano_work API which is useful when
handling timeouts since the same stack/workqueue can be shared.

By default, kernel event logger is using the system timer. But on
some platforms where the timer driver maintains the system timer
cycle accumulator in software, such as ones using the LOAPIC timer,
the system timer behavior leads to timestamp errors. For example,
the timer interrupt is logged with a wrong timestamp since the HW
timer value has been reset (periodic mode) but accumulated value not
updated yet (done later in the ISR).
This patch is adding the possibility to register a timer callback
function that will be used by the kernel event logger. For example,
on Quark SE, this allows using RTC or AON counter which accuracy is
sufficient and behavior more straight forward compared to system
timer.

Add a generic API for drivers to start workqueues and submit work

sleep from an ISR to run in fiber context.
Also add the option to start a system-wide workqueue.
Both additions are optional. They can be deactivated for systems that

The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).
It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.

Microkernel timers are defined at compile time as a static list
but they are allocated dynamically in kernel execution.
The object tracing list will only list those timers that are
currently allocated at debug time. For this reason, timers
can be removed from the tracing list at any time.
A very simple double linked list was implemented to reduce the
complexity of the action to remove an item from the list from O(n)
to O(1) and simplify the remove implementation.

a simple single-linked list implementation that allows
to save space and simplifies the access to the data for
debug tools such as gdb.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.
