Benoît Thébaudeau a52a3d94d3 cc2538: uart: Fix garbled output occurring upon lpm_enter()
lpm_enter() must not enter PM1+ if the UART is transmitting. Otherwise,
the UART clock gets disabled, and its TX is broken.

The commit b8b54a033c had already
partially fixed this issue, but it could still occur while transmitting
stop bits because, contrary to UART_FR.BUSY, UART_FR.TXFE takes only the
data bits into account, not the stop bits.

George Oikonomou 568973f6ec Don't flush the CC2538 RF RX FIFO unconditionally
After reading a frame, `read()` checks the status of the RX FIFO:

* If an overflow is detected, the FIFO gets flushed
* If there are more frames in the FIFO, the `cc2538_rf_process` will get polled again in order to read out the next frame.

#1550 changed `read()`, which now performs the above check for non-poll mode, but it then flushes the FIFO unconditionally. Therefore, if there are two or more frames in the FIFO, they will get flushed before the `cc2538_rf_process` has had a chance to read them out. This results in missed frames.

Reproducing this is trivial: Build a CC2538 sniffer and see how it will never show you .15.4 ACK frames. ACK reception completes while `read()` is still streaming the previous captured frame to the host. Upon completion, the FIFO will get flushed and the ACK will get lost.

This pull proposes removing the unconditional flush and reverting to the original logic for non-TSCH operation.

Pinging @thomas-ha here for input regarding poll mode.

This pull sits on top of #1778

Benoît Thébaudeau 1da00a482f cc2538: aes: Fix possibly missing result available status
Depending on the use case and on the timings,
aes_auth_crypt_check_status() sometimes never reported an available
result, leading to a deadlock of any protothread waiting for this event,
and to a WDT reset if a protothread was polling it.

This was caused by aes_auth_crypt_start() clearing the result available
interrupt after operations that may rightfully trigger it, leading to a
missed interrupt.

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.
