Glenn Ruben Bakke 2489688635 nrf/boards: Update memory.ld to include bootloader offsets.
Adding variables that can be set from other linker scripts:

- _bootloader_head_size:
    Bootloader flash offset in front of the application.

- _bootloader_tail_size:
    Bootloader offset from the tail of the flash.
    In case the bootloader is located at the end.

- _bootloader_head_ram_size:
    Bootloader RAM usage in front of the application.

Updated calculations of application flash and RAM.

Joris Peeraer 5020b14d54 py/mpprint: Fix length calculation for strings with precision-modifier.
Two issues are tackled:

1. The calculation of the correct length to print is fixed to treat the
   precision as a maximum length instead as the exact length.
   This is done for both qstr (%q) and for regular str (%s).

2. Fix the incorrect use of mp_printf("%.*s") to mp_print_strn().

   Because of the fix of above issue, some testcases that would print
   an embedded null-byte (^@ in test-output) would now fail.
   The bug here is that "%s" was used to print null-bytes. Instead,
   mp_print_strn is used to make sure all bytes are outputted and the
   exact length is respected.

Test-cases are added for both %s and %q with a combination of precision
and padding specifiers.

Maureen Helm 92a5ee6ac1 zephyr: Replace broken shell_net_iface() with more general shell_exec().
The zephyr function net_shell_cmd_iface() was removed in zephyr v1.14.0,
therefore the MicroPython zephyr port did not build with newer zephyr
versions when CONFIG_NET_SHELL=y. Replace with a more general
shell_exec() function that can execute any zephyr shell command. For
example:

>>> zephyr.shell_exec("net")

  allocs     :Print network memory allocations.
  arp        :Print information about IPv4 ARP cache.
  conn       :Print information about network connections.

Damien George cb1bb7592e stm32/Makefile: Change -O0 to -Og for DEBUG=1 builds.
The -Og optimisation level produces a more realistic build, gives a better
debugging experience, and generates smaller code than -O0, allowing debug
builds to fit in flash.

This commit also assigns variables in can.c to prevent warnings when -Og is
used, and builds a board in CI with DEBUG=1 enabled.

Jim Mussared c4d08aa4e3 extmod/modbluetooth: Add support for bonding (key persistence).
This adds `_IRQ_GET_SECRET` and `_IRQ_SET_SECRET` events to allow the BT
stack to request the Python code retrive/store/delete secret key data.  The
actual keys and values are opaque to Python and stack-specific.

Only NimBLE is implemented (pending moving btstack to sync events).  The
secret store is designed to be compatible with BlueKitchen's TLV store API.

Damien George ca40eb0fda extmod/uasyncio: Delay calling Loop.call_exception_handler by 1 loop.
When a tasks raises an exception which is uncaught, and no other task
await's on that task, then an error message is printed (or a user function
called) via a call to Loop.call_exception_handler.  In CPython this call is
made when the Task object is freed (eg via reference counting) because it's
at that point that it is known that the exception that was raised will
never be handled.

MicroPython does not have reference counting and the current behaviour is
to deal with uncaught exceptions as early as possible, ie as soon as they
terminate the task.  But this can be undesirable because in certain cases
a task can start and raise an exception immediately (before any await is
executed in that task's coro) and before any other task gets a chance to
await on it to catch the exception.

This commit changes the behaviour so that tasks which end due to an
uncaught exception are scheduled one more time for execution, and if they
are not await'ed on by the next scheduling loop, then the exception handler
is called (eg the exception is printed out).

Damien George bb24c69b90 lib/utils/pyexec: Add stdin-reader on raw REPL with flow control.
Background: the friendly/normal REPL is intended for human use whereas the
raw REPL is for computer use/automation.  Raw REPL is used for things like
pyboard.py script_to_run.py.  The normal REPL has built-in flow control
because it echos back the characters.  That's not so with raw REPL and flow
control is just implemented by rate limiting the amount of data that goes
in.  Currently it's fixed at 256 byte chunks every 10ms.  This is sometimes
too fast for slow MCUs or systems with small stdin buffers.  It's also too
slow for a lot of higher-end MCUs, ie it could be a lot faster.

This commit adds a new raw REPL mode which includes flow control: the
device will echo back a character after a certain number of bytes are sent
to the host, and the host can use this to regulate the data going out to
the device.  The amount of characters is controlled by the device and sent
to the host before communication starts.  This flow control allows getting
the maximum speed out of a serial link, regardless of the link or the
device at the other end.

Also, this new raw REPL mode parses and compiles the incoming data as it
comes in.  It does this by creating a "stdin reader" object which is then
passed to the lexer.  The lexer requests bytes from this "stdin reader"
which retrieves bytes from the host, and does flow control.  What this
means is that no memory is used to store the script (in the existing raw
REPL mode the device needs a big buffer to read in the script before it can
pass it on to the lexer/parser/compiler).  The only memory needed on the
device is enough to parse and compile.

Finally, it would be possible to extend this new raw REPL to allow bytecode
(.mpy files) to be sent as well as text mode scripts (but that's not done
in this commit).

Some results follow. The test was to send a large 33k script that contains
mostly comments and then prints out the heap, run via pyboard.py large.py.

Same but with this PR:

The only thing in RAM is the compiled script (and some other unrelated
items).

Time to download before this PR: 1438ms, data rate: 230,799 bits/sec.

Time to download with this PR: 119ms, data rate: 2,788,991 bits/sec.

So it's more than 10 times faster, and uses significantly less RAM.

Results are similar on other boards. On an stm32 board that connects via
UART only at 115200 baud, the data rate goes from 80kbit/sec to
113kbit/sec, so gets close to saturating the UART link without loss of
data.

The new raw REPL mode also supports a single ctrl-C to break out of this
flow-control mode, so that a ctrl-C can always get back to a known state.
It's also backwards compatible with the original raw REPL mode, which is
still supported with the same sequence of commands.  The new raw REPL
mode is activated by ctrl-E, which gives an error on devices that do not
support the new mode.
