This patch replaces the pinmux APIs that require users to look up an arbitrary
function number for the desired function of each pin. The replacement API
functions have intuitive names and permit users to pass board-level IO port
numbers. The API functions internally convert those to CPU-level port numbers
when necessary. Furthermore, when configuring a pin to be a digital input or
output, those API functions also perform the corresponding configuration
operation on the CPU-level GPIO port. The revised APIs halt when users attempt
to configure a currently-unsupported GPIO, specifically those in the GPIO_SUS
port range and those implemented on the expander chip EXP2. This also means
that such ports are left unconfigured during initialization, whereas the
pinmuxing for them was setup by the old implementation.
This patch refactors the pinmux configuration code for Intel Galileo to simplify
it. This patch also corrects an off-by-one error in how the pin number is
checked in galileo_pinmux_set_pin.
Enable the 32.768-kHz crystal on all the CC2538 platforms where it is
present in order to get a better time accuracy.

This patch fixes UART system call authorization initialization (when
protection domain support is enabled) to only initialize the system call
entrypoint and authorization data structures once, prior to per-port
setup. Previously, if two UARTs were configured, the setup procedure for
the second UART would erase the system call authorization for the
first (console) UART, resulting in a crash upon the next attempt to
perform console output.
This patch adds a Dockerfile for building a container configured as a
build environment for Intel Galileo boards. This patch also provides
documentation for using the containerized build environment. Finally, it
streamlines the instructions for booting Contiki on Galileo and includes
other documentation refinements.
#1684 slightly varied RF startup time and, as a result, threw ContikiMAC timing configuration off. This manifests itself with very poor CC13xx PROP mode radio performance, as documented in #1747.
This pull fixes this bug by slightly increasing ContikiMAC's inter-packet interval. This gives the receiver a little more time to respond with an ACK to unicast frames.
Fixes#1747
