Benoît Thébaudeau bd961d1cd3 cc2538: Fix possible linker script breakage
The conditional definitions in project-conf.h depending on
CONTIKI_TARGET_<TARGET_NAME> were ignored at link time, which broke the
linker script if it used these definitions, so the flashed applications
could crash or malfunction.

Add generic AES functions that should be able to support all the modes
of operation of the hardware AES crypto engine, i.e. ECB, CBC, CTR,
CBC-MAC, GCM, and CCM.

This makes it possible to easily implement these modes of operation
without duplicating code.

Benoît Thébaudeau 4a6e19ed38 cc2538: pwm: Automatically disable PM1+ if running
The peripheral core clocks of the PWM timers are gated in PM1+, so these
power modes must be disabled if a PWM timer is running. Use
lpm_register_peripheral() to handle this automatically and dynamically.

Benoît Thébaudeau 5b1457e4ab cc2538: Fix stack alignment
According to the Procedure Call Standard for the ARM Architecture
(AAPCS) - ABI r2.09 [1], §5.2.1.2, the stack pointer must be
double-word-aligned at a public interface. The stack implementation
being full-descending, this requires that the top of stack be
double-word-aligned too.

Benoît Thébaudeau 5d98cb71e2 cc2538: Add support for Coffee
Coffee is placed by default at the beginning of the flash memory, right
before the firmware. This avoids the memory gaps that there could be
before and after Coffee if it were placed after the firmware, because it
is unlikely that the end of the firmware is aligned with a flash page
boundary, and the CCA is not flash-page-aligned. Thanks to that, Coffee
is also always in the same flash area if its size remains unchanged,
even if the firmware changes, which makes it possible to keep the Coffee
files when reprogramming the firmware after a partial flash erase
command.

The default configuration of Coffee is set to use sensible values for a
typical usage on this SoC, i.e. for sensor data logging.

The default size of Coffee is set to 0 in order not to waste flash if
Coffee is unused.

COFFEE_CONF_CUSTOM_PORT can be defined to a header file to be used with
"#include" in order to override the default CC2538 port of Coffee. This
makes it possible to use Coffee with an external memory device rather
than with the internal flash memory, without having to alter the Contiki
files.

Benoît Thébaudeau ee3ee049e4 cc2538: Set the entry point to the CCA
No entry point was defined, so it defaulted to the beginning of the
.text output section where the vector table is located by default in
Contiki. Actually, the vector table may be located elsewhere, and the
ROM-based boot loader first reads the CCA to find the vector table.

Consequently, this commit sets the entry point to the CCA, which fixes
both the entry point and the initial symbol reference, so this commit
also removes the now-unneeded "__used__" and "KEEP" keywords from the
CCA.

Benoît Thébaudeau 96dd24836c cc2538: Use &vectors instead of flash/.text start address
The current CC2538 linker script in Contiki places the vector table at
the beginning of the flash memory / .text output section. However, this
location is arbitrary (the only requirement is that the vector table is
512-byte aligned), and custom linker scripts may be used with Contiki,
which means that Contiki may be used with a vector table placed
elsewhere. Thus, using the flash/.text start address in the CCA and as
the default NVIC VTABLE value was wrong.

This commit rather uses the address of the vectors[] array from
startup-gcc.c, which makes it possible to freely move around the vector
table without breaking anything or having to use a custom startup-gcc.c
and to configure the NVIC driver for that. Moreover, referencing the
vectors[] array naturally prevents it and its input section from being
garbage-collected by the linker, so this commit also removes the
now-unneeded "used" and "KEEP" keywords from the vector table.

Benoît Thébaudeau a191fcdb84 cc2538: nvic: Simplify VTABLE configuration
The only thing needed for VTABLE is the absolute address of the vector
table. Splitting it between code/SRAM base and offset complicates things
and brings nothing.

Consequently, this commit merges the NVIC VTABLE configurations into a
single one giving the vector table absolute address.

Benoît Thébaudeau 790c253d6d cc2538: Define and use device features
Define the available CC2538 devices and their features, and use them to
define the linker script memory regions. The .nrdata output section is
now always defined in order to trigger an error if it is used but no
memory is available for it. The CC2538 device used by Contiki is made a
configuration option, the CC2538SF53 device being the default.

This makes more sense than defining the flash memory address and size as
configuration options like previously, all the more not all values are
possible and all the features are linked by each device.

This change also makes it possible to:
 - use the correct SRAM parameters for the CC2538NF11,
 - know at build time if the AES, SHA, ECC and RSA hardware features are
   available on the selected CC2538 device.
