Johan Hedberg 2893def459 drivers/console: shell: Add custom prompt callback support
Shell applications may want to have a dynamic prompt rather than a
fixed string. Add a new API to let the application specify a custom
callback instead of using the fixed string given to shell_init().

Add shell_register_app_cmd_handler for an to app to optionally call so
that it can receive cmdlines not handled by the cmds registered with
shell_init

Benjamin Walsh 760f191b1e debug: add safe memory access routines
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).

Michael LeMay ebba3bf38b eth: dw: Add driver for Synopsys DesignWare Ethernet MAC
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.

Andrew Boie f18f102feb nanokernel: add optional ring buffer data type
This patch is based on some code contributed by Dirk Brandewie.

This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.

Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.

Benjamin Walsh 0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

off to show the minimal footprint. On ARC, printk() is being used
in some core IRQ management code, resulting in a build error.

On other OSes such as Linux, disabling printk() causes any use
of them to compile to nothing rather than generate a build error.
We should do the same here, we shouldn't try to discourage the use
of console logs in the codebase.

Benjamin Walsh ca51a72133 dlist: enhance library and make all functions inline
The old doubly-linked list implementation had only support for very
basic operations, i.e. add at head and remove.

The new implementation is highly enhanced, allowing these operations:

- initialize list
- check if a node is the list's head
- check if a node is the list's tail
- check if the list is empty
- get a reference to the head item in the list
- get a reference to the next item in the list
- add node to tail of list
- add node to head of list
- insert node after a node
- insert node before a node
- insert node at position based on condition
- remove a specific node from a list
- get the first node in a list

The implementation is completely inline, since the operations are rather
simple and do not warrant a function call.
