This bl updater can be flashed as app and will update the bootloader and
then
delete itself before resetting the sam3, so the device will end up in
the newly
updated dfu bootloader afterwards, without having to press the
bootloader button
or requring any other manual interaction, ready to receive a new
application image.
Building the blupdater requires a previously built dfu-flash bootloader
bin file that
will then be embedded into the app during building.

The "wait time extension timer" was apparently not being reset during
normal tx operations, which led to occasional NULL (0x60) bytes getting
injected into transfers, which in turn led to more tx bytes than what
the reader side expects...
The odd thing is that this was only noticeable with high baud rates,
probably due to the very long default WT of 9600 ETU, and even then only
because it led to weird ngff modem resets after benign transfers.

Single threaded evaluation is (assumed to be!) left to right, depth
first - but with concurrent make using -j this breaks, because the
actual usb string header is generated after the attempt to concurrently
compile the code that needs it, since there is no explicit order among
the all: dependencies.
This is fixed by properly adding a dependency on that header.

This adds support for the new ngff_cardem board, a board that
basically combines a ngff breakout board with a built-in SIMtrace2.
Cardem works, but depending on the modem it might need a adjusted ATR to
ensure a lower baud rate is used by the modem, high rates might lead
to weird power cycling of the card after a few transfers.
Trace was also tested and appears to work as expected.

The tester has shifters, while the original simtrace relies upon the
reader restarting the powerup attempt with > 1v8 after not respondig due
to a lack of shifters and therefore 1v8 support.

Back in I8c9b0c3d862a967832134b24252577739182da62 we added support

octsimtest has a resistive voltage divider in front of the VCC ADC
in order to also detect 5V. We must make the thresholds board-specific
and adjust them for octsimtest.

Contrary to other hardware designs, octsimtest has a level-shifter in
the I/O line to support testing with 1.8, 3 and 5V. This level shifter
is bi-directional, but the direction needs to be explicitly specified
via the SIM_IO_DIR signal attached to PA26.

As we store the waiting time (WT) in 'etu', we must adjust the formula
from ISO 7816-3. The 'Fi' component in the formula only exists to
compute clock cycles from the etu, which we don't need here.
Without this patch, the waiting time would be way too large (by a factor
of 372 in the default case).

The existing code started the timer once (and expired once) but didn't
properly handle re-starting of the timer. Neither did it handle
the 'half time expiration' case. If we want to call a function after
half the WT expiring, we must of course program the hardware for half
the timeout, and not the full timeout...

Instead of using the timer/counter peripheral to handle the waiting time
and corresponding timeout, the USART peripheral internal timeout
mechanism is used.
This is particularly important for the SIMtrace board since there
(contrary to other boards) the I/O signal is not wired to a TIO pin
of the timer/counter block, and hence Rx/Tx data cannot reset that
timer/counter.
As a result of this migration, cardem is now supported not only on
owhw + qmod, but also on the simtrace board.
The guts of this change have been lifted out of Change-Id
Ibcb2c8cace9137695adf5fb3de43566f7cfb93b5 by Kevin Redon, which was
unfortunately touching various different topics at the same time and
hence was split up. Some improvements are the introduction of the
ENABLE_TX_TIMER_ONLY mode, which avoids the USART interrupt handler
getting hammered with TXRDY between release of RST and start of the ATR.

Fi/Di are not the index into the table, but the contents of the table
as resolved by Fi_index / Di_index. Let's clarify the terminology.
Change-Id: If364e08e7c9a3a9707e6d54b9267c6a7c088e415
The ISO7816 spec terms are well-defined, let's not abuse them. We used
to consider "Fi" as the "index into the table of F values", while the
spec actually considers Fi as the initial value for F.
Let's make sure we use the terms quite clearly:
* Fi and Di are the initial values for F and D
* F*_index and D*_index are the indexes into the ISO7816-3 Tables
Furthermore, let's track Fi separately from F, as e.g. the waiting
time definition only considers Fi as indicated in the ATR, despite
an actually different F value might have been negotiated via PTS
meanwhile.

As we will soon introduce the distinction between Fi and F, we should
use uppercase letters, as lower-case 'f' is defined in ISO7816-3 as
the frequency, which is different from the upper-case 'F'.

The comment didn't reflect the source. I checked all users and

Disable stack protector for all boards/apps by default, not only
qmod-dfu. Use 'make STACK_PROTECTOR=1' to enable.
This was recommened by Eric:
"I'd argue that we do not want this in general, since it adds canaries
to all functions that deal with buffers, and therefore impacts the
overall timing in a non determinstic way depending on inlining and
optimizations, while contributing nothing in non debug builds."

For some reason undefined symbols were downgraded to warnings, which
means building a firmware that calls missing functions (= address zero)
was perfectly fine, which of course made development more exciting....
This applies to builtins, too, printf of one char gets downgraded to
putchar, which we don't have, so disable builtins.
