George Oikonomou 807ee624e4 Confine CC2538 WDT on/off conf inside the driver
Instead of requiring all calls to `watchdog_start` to be
wrapped inside `#if WATCHDOG_CONF_ENABLE` guards, we control
things from within the WDT driver itself.

This commit also includes some minor documentation and
indentation cleanups

George Oikonomou 08c884afa0 Improve the CC2538 extended RF API implementation
* Decouple 64-bit address from LINKADDR_SIZE
* get and set object from/to the start/end of the src/dest buffer
* We expect size == 8 (rather than size < 8) for both get_ and set_object. Error otherwise
* The RF no longer sets parameters by itself. We let the platform do this, using the extended API.

Brad Campbell af27d2d252 [CC2538-SPI] Implement SPI_FLUSH, spi mode, !CS
Because the CC2538 has a multi-byte SPI RX FIFO, flushing the buffer
requires more than just a single read. This adds a loop that empties the
entire RX buffer on a FLUSH().

Different SPI chips needs different SPI settings. This commit adds a
function that allows chip drivers to configure the SPI peripheral before
using it.

The frame pin the driver was using as a chip select does not work as
most devices expect it to. It toggles after every byte, and most chips
interpret that as end of message. To make drivers more reliable, each
chip driver should setup a GPIO and assert it as needed.

George Oikonomou eed1352282 Fix CC2538 random_init lockup
Contiki sometimes fails to boot correctly and locks up in
random_init()

This problem only manifests itself for specific versions
of the arm-gcc toolchain and then again only for specific
levels of optimisation (-Os vs -O2, depending on the
value of the SMALL make variable)

The lockup is caused when we write an RFCORE XREG before
the RF clock ungating has taken effect, which in turn
only occurs depending on the assembly generated for those
two instructions:

  REG(SYS_CTRL_RCGCRFC) = 1;

  REG(RFCORE_XREG_FRMCTRL0) = 0x00000008;

This commit makes the RNG wait for the ungating to take
effect before attempting to write the register

Brad Campbell d14f0d5eed CC2538: add secondary location to ieee address
The CC2538 currently has two addressing options: a hardcoded address set
at compile time or the address stored in primary address section of the
info page. This commit adds the option to choose the secondary location
of the ieee address from the info page, or any memory address.

To use, define `IEEE_ADDR_CONF_USE_SECONDARY_LOCATION` in `project-conf.h`
or similar.

For example:

    #define IEEE_ADDR_CONF_USE_SECONDARY_LOCATION 1

George Oikonomou 332d56ac11 Make some CC2538 CFLAGS and LDFLAGS common
Some CFLAGS and LDFLAGS previously only enabled with SMALL=1 have
now been enabled for all builds, regardless of the value of SMALL.

Therefore, from now on, SMALL only chooses between -Os and -O2

George Oikonomou a63376f8be Use -Os for CC2538 builds
As discussed in #503, -Os was broken with one of the toolchains
recommended in the platform's README and for that reason we were
using -O2 by default.

This commit sets the default to -Os and updates the README to no
longer recommend the toolchain in question

Benoît Thébaudeau 42c287f363 cc2538: lpm: Fix build for LPM_CONF_ENABLE == 0
lpm.c needs to #include lpm.h in order to get the definition of
lpm_periph_permit_pm1_func_t, which made the replacement macros conflict with
the function definitions for the LPM_CONF_ENABLE == 0 case. This change fixes
this issue by #if-ing out the code in lpm.c in that case. Also, the replacement
macro for lpm_register_peripheral() was missing in that case, which is fixed
here.

Benoît Thébaudeau a562acb160 cc2538: Fix library linkage
If a project needs to use some libraries at link stage, then the corresponding
linker options (e.g. '-lm') have to be passed after any .o file depending on
these libraries. Hence, LDFLAGS cannot be used to add such options when invoking
$(LD) in Makefile.cc2538, or it should be moved to the correct location.
Instead, this change adds TARGET_LIBFILES to the correct location, like most
other Contiki targets.
