This adds support for flashing to multiple devices, by implementing the
$MOTES option used by the Z1.
This replaces the $PORT interface, as it only allowed flashing to one
device at a time, and the $MOTES interface was still used for other
tasks (such as getting a list of connected devices).
A foreach loop is used to dynamically create an upload rule per device
that needs to be flashed.
The "main" upload rule depends on the device specific ones.
This allows for parallel flashing.
The PORT variable can still be sued for backwards compatibility.
Changed the MOTES variable that makes a $(shell) call to not be
recursively expanded.
According to the CC1310LP design files, the flash on it is the same as the flash on the CC2650 LP (MX25R8035F 8Mbit). However, the flash on some CC1310 LPs reportedly identifies itself as the 16Mbit one (MX25R1635F). Instruction sets are identical, we simply need to tell the driver to recognise this part's Device ID.
The block that controls the `.upload` target is unnecessarily replicated in multiple sub-board Makefiles. This was originally done because the SmartRF and the Launchpad can be programmed with the c2538-bsl script, whereas the sensortag cannot.
This commit moves the `cc2538-bsl` / `.upload` target logic to the top level cpu Makefile (`cpu/cc26xx-cc13xx/Makefile.cc26xx-cc13xx`). Board makefiles simply set the make variable `BOARD_SUPPORTS_BSL` to 1 to signal that they can be programmed by the BSL script. If `BOARD_SUPPORTS_BSL` is not equal to 1, trying to use the `.upload` target will return an error message.
For example:
```
$ make BOARD=sensortag/cc2650 cc26xx-demo.upload
using saved target 'srf06-cc26xx'
This board cannot be programmed with the ROM bootloader and therefore does not support the .upload target.
```
Two errors have been spotted, when IPv6 is enabled in the ravenusb
Project-Makefile:
#CONTIKI_NO_NET=1
CONTIKI_WITH_IPV6=1
The compile error results from a variable name mismatch in cdc_task.c
The variable 'r' is undeclared and should be renamed to 'route'
The linker also fails with 'undefined references'
This has been mediated by adding 'core/net' to Modules in the
Project-Makefile.
This patch adds a simple non-driver protection domain sample to serve
as an example for defining other non-driver protection domains. It
simply performs a ping-pong test of protection domain switching
latency during boot, including optional accesses to a private metadata
region, and prints out the results.
This patch extends the protection domain framework with an additional
plugin to use Task-State Segment (TSS) structures to offload much of
the work of switching protection domains to the CPU. This can save
space compared to paging, since paging requires two 4KiB page tables
and one 32-byte page table plus one whole-system TSS and an additional
32-byte data structure for each protection domain, whereas the
approach implemented by this patch just requires a 128-byte data
structure for each protection domain. Only a small number of
protection domains will typically be used, so
n * 128 < 8328 + (n * 32).

GCC 6 is introducing named address spaces for the FS and GS segments
[1]. LLVM Clang also provides address spaces for the FS and GS
segments [2]. This patch also adds support to the multi-segment X86
memory management subsystem for using these features instead of inline
assembly blocks, which enables type checking to detect some address
space mismatches.
