Billy Kozak 324d03b53c CC26xx - fully shutdown the rf-core & abort rx op
Prior to this patch, the ieee radio driver did not explicitly abort
the rx operation or power down the analog components of the radio
prior to shutting down the rf-core.

The result of this was that the rf-core continued to use a lot of
power even while "off".

This patch fixes this problem.

Billy Kozak dfdb0a6487 cc26xx - fixed WDT reloading
According to the TRM, the WDT does not produce a reset until it
expires twice. After expiring the WDT will set the INT flag if it
is unset, and reset the MCU if INT is already set.

Before this patch, watchdog_periodic() only un-sets the INT flag. This
means that the behaviour of watchdog_periodic is underministic in that
the value of the countdown timer will be different depending on
when the function was called.

This patch fixes this behaviour by also reloading the timout value.

Jonas Olsson 01e36532c2 Add support for the CC13xx CPU
This commit:

* Moves all cpu files from cpu/cc26xx to cpu/cc26xx-cc13xx
* Bumps the CC26xxware submodule to the latest TI release
* Adds CC13xxware as a submodule
* Adds support for sub-ghz mode / IEEE 802.15.4g
* Splits the driver into multiple files for clarity. We now have the following structure:
  * A common module that handles access to the RF core, interrupts etc
  * A module that takes care of BLE functionality
  * A netstack radio driver for IEEE mode (2.4GHz)
  * A netstack radio driver for PROP mode (sub-ghz - multiple bands)

This commit also adds tick suppression functionality, applicable to all chips of the CC26xx and CC13xx families. Instead waking up on every clock tick simply to increment our software counter, we now only wake up just in time to service the next scheduled etimer. ContikiMAC-triggered wakeups are unaffected.

Laslty, this commit also applies a number of minor changes:
* Addition of missing includes
* Removal of stub functions
* Removal of a woraround for a CC26xxware bug that has now been fixed

Billy Kozak feec05cdf2 CC26xx - fix misuse of len variable in read_frame
read_frame was misuing the packet length in the following ways:
- returning non-zero even if buf_len is too short for the packet
- truncating the length to buf_len if len is too long then using the
  truncated (i.e. wrong) length to index into the buffer
- memcpying too many bytes (used buf_len instead of real length)

This commit fixes all of this and adds some code to report
on packet length errors (to match with cc2538 driver).

Oliver Schmidt ca2552461e Adjusted retro target clock to "new" DNS resolver.
The DNS resolver requires 1/4 sec clock resolution. The retro targets had a 1/2 sec clock resolution (optimized for the 1/2 sec TCP timer) resulting in DNS resolver timeouts being 0. Therefore the retro target clock resolution is now increased to 1/4 sec.

Oliver Schmidt f348f4feb2 Allow fixup to be repeated.
There are scenarios in which it is beneficial to search for an Etherne chip at several i/o locations. To do so the chip initialization is performed at several i/o locations until it succeeds. In order to allow for that operation model the i/o location fixup needs to be repeatable.

Note: This won't work with the RR-Net because the fixup bits overlap with the chip i/o bits.

George Oikonomou b4ec0c7c1d Remove doxygen explicit links to non-existing symbols
Parts of the stm32w108 doxygen comments have explicit links to symbols that do not exist anywhere in our source base, let alone be documented. This is likely to be caused by a partial import of manufacturer libraries in the Contiki source tree.

These links were previously not generating warnings in the doxygen log because we were not defining `DOXYGEN_SHOULD_SKIP_THIS` and they were thus being skipped altogether by the doxygen pre-processor. Defining `DOXYGEN_SHOULD_SKIP_THIS` causes those doxygen comments to get processed and to thus generate warnings.

This commit removes explicit links to non-existent symbols and updates `doxyerrors.cnt` accordingly.

Benoît Thébaudeau b92a5afcc4 cc2538: ccm: Make it possible to use the interrupt
Using the AES interrupt allows the user process not to waste time
polling for the completion of the operation. This time can be used by
the user process to do something else, or to let the system enter PM0.

Since the system is now free to perform various operations during a
crypto operation, a protection of the crypto resource is added, and PM1+
is prohibited in order not to stall crypto operations.

George Oikonomou d28eb023ef Remove CC2530 and CC2538 dummy watchdog_stop()
The CC2538 the WDT cannot be stopped once it has been started.
The CC2530/1 WDT can be stopped if it is running in timer mode,
but it cannot be stopped once it has been started in watchdog mode.

Both platforms currently provide "dummy" implementations of `watchdog_stop()`,
one does nothing and the other one basically re-maps `_stop()` to
`_periodic()`.

This was originally done in order to provide implementations for all prototypes
declared in `core/dev/watchdog.h`. In hindsight and as per the discussion
in #1088, this is bad practice since, if the build succeeds, the caller will
expect that the WDT has in fact been stopped, when in reality it has not.

Since the feature (stopping the WDT) is unsupported by the hardware, this pull
removes those dummy implementations. Thus, we will now be able to reliably
detect - at build time - attempts at using this unsupported feature.

Benoît Thébaudeau 1cd3c9e7e5 cc2538: Initialize .data/.bss using ROM functions
This is safer because the previous code assumed that the start and end
VMAs of .data and .bss were word-aligned, which is not always the case,
so the initialization code could write data outside these sections. The
ROM functions support any address boundary.

This is faster because the ROM functions are ultra optimized, using
realignment and the LDM/STM instructions, which is much better than the
previous simple loops of single word accesses.

This is smaller because the ROM functions don't require to add any code
to the target device other than simple function calls.

This makes the code simpler and more maintainable because standard
functions are not reimplemented and no assembly is used.

Note that this is also faster and smaller than the corresponding
functions from the standard string library.

Benoît Thébaudeau 0de729572b cc2538: Word-align .data LMA
In order to be fast, the reset_handler() function uses word accesses to
initialize the .data output section. However, most toolchains do not
automatically force the alignment of an output section LMA to use the
maximum alignment of all its input sections. Because of that, assuming
that .data contains some words, the LMA of the .data output section was
not word-aligned in some cases, resulting in an initialization performed
using slow unaligned word accesses.

This commit forces the alignment of the LMA of the .data output section
with a word boundary in order to always use fast aligned word accesses
to read the .data load area.

Note that this solution is better than using ALIGN_WITH_INPUT, both
because the latter is a new feature incompatible with older toolchains,
and because it could create a big gap between _etext and the LMA of
.data if strongly-aligned data were added to .data, although only a word
alignment is required here.

The same considerations apply to the VMA of .data. However, it is
already automatically word-aligned, both because .data contains words,
and because the end VMA of the previous output section (.socdata) is
word-aligned. Moreover, if the VMA of .data were forcibly word-aligned,
then a filled gap could appear at the beginning of this section if
strongly-aligned data were added to it, thus wasting flash memory.
Consequently, it's better not to change anything for the VMA of .data,
all the more it's very unlikely that it does not contain any word and
that the end VMA of .socdata becomes non-word-aligned, and this would
only result in a slower initialization.

Benoît Thébaudeau 0d260f61a0 cc2538: Fix .data LMA/VMA mismatch with some toolchains
Some toolchains, like Sourcery CodeBench Lite 2013.05-23 arm-none-eabi
(http://sourcery.mentor.com/public/gnu_toolchain/arm-none-eabi/)
automatically force the alignment of an output section LMA to use the
maximum alignment of all its input sections. This toolchain uses GNU
binutils 2.23, and this automatic behavior is the same as the manual
behavior of the ALIGN_WITH_INPUT feature of GNU binutils 2.24+.

This behavior is not an issue per se, but it creates a gap between
_etext and the LMA of the .data output section if _etext does not have
the same alignment, while reset_handler() initialized this section by
copying the data from _etext to its VMA, hence an offset in the
addresses of loaded data, and missing data.

This commit fixes this issue by making reset_handler() directly use the
LMA of the .data section using LOADADDR(.data), rather than assuming
that _etext is this LMA.

George Oikonomou 07272b7cd6 Improve UART power-cycling logic:
* Only enable TX by default.
* Add some magic for RX handling. When an input handler is registered:
  * Automatically enable RX-related and interrupts
  * Automatically lock the SERIAL PD on under all power modes
  * Automatically enable the UART clock under sleep and deep sleep
  * Automatically undo all of the above when the input handler becomes NULL
  * As a result, modules / examples that need UART RX no longer need to clock the UART and manipulate the SERIAL PD. They simply have to specify an input handler
* Don't automatically power on the UART whenever the CM3 is active
* Before accessing the UART, make sure it is powered and clocked
* Avoid falling edge glitches
* Fix garbage characters / Explicitly wait for UART TX to complete

George Oikonomou 34f52ed08e Improve the LPM module:
* Implement new style of PD locks
* Use our own shutdown sequence rather than the one provided by cc26xxware
* Shutdown from within the interrupt that requested it. This allows shutdown to take place even if the code is stuck in a loop somewhere else
* Improve DCDC/GLDO/uLDO switching logic
* Explicitly handle oscillators and retentions

George Oikonomou 421fbfae25 Change the LPM locks API:
Instead of using a separate data structure to request that a PD remain powered during deep sleep,
we do the same within the main LPM data structure through an additional field.

This allows us to maintain only one linked list of LPM modules and overall improves code clarity
