This adds a script to generate the peripherals files (except clock).
It adds support for the 1015, 1020, 1040, and 1050 EVKs.
Some work was started on 1176 but it isn't working. So, the board
def is in a separate branch.
Fixes#3521. Fixes#2477.
API change: time.time_ns() is added, but it just returns 0.
No API or functional change to existing time functions.

Since c80e7c14e6305e50e3b39f97172d4d8fe1214d3b changed the GC heap to use
all unused RAM, there is no longer any RAM available for the traditional C
heap (which is not used by default in MicroPython but may be used by C
extensions). This commit adds a provision for a board to reserve RAM for
the C heap, by defining MICROPY_C_HEAP_SIZE.

The previous code worked on ESP32 but not ESP32-S3. All the IDF (v4.4.3)
examples call rmt_set_tx_loop_mode before rmt_write_items, so make that
change here.

- Use the same colour formatting.
- Add a tool to convert to .pcap for Wireshark.

This adds a mechanism to track a pending notify/indicate operation that
is deferred due to the send buffer being full. This uses a tracked alloc
that is passed as the content arg to the callback.
This replaces the previous mechanism that did this via the global pending
op queue, shared with client read/write ops.

Makes gatts_notify and gatts_indicate work in the same way: by default they
send the DB value, but you can manually override the payload.
In other words, makes gatts_indicate work the same as gatts_notify.
Note: This removes support for queuing notifications and indications on
btstack when the ACL buffer is full. This functionality will be
reimplemented in a future commit.

Spotted the Cosmo_pico port on circuitpython.org which is the same class of device as the Pimoroni PICO dv so I'm switching the VID/PID to use the Raspberry Pi owned values rather than the Adafruit values just as the Como device uses.
Don't idle from main if we scheduled an interrupt for 0 ticks in
the future.
Have RP2040 detect wakes that happen between setting the timer and
the idle call.
Fixes#7361
The Wio Terminal includes a RealTek RTL8720D as a companion to the main chip to provide WiFi and Bluetooth capabilities via eRPC over a UART connection. The WIO Terminal schematic labels some pins as the RXD/TXD for the UART, and that was captured in the board definition for CircuitPython. However, these pins may be used for logging in another mode, but they are not the main pins used to communicate with the RTL chip. The correct configuration is RX on PC24/pad 2 and TX on PB24/pad 0 of SERCOM 0. The comments on the pin definitions now reflect this situation, for anyone trying to get the WiFi/BLE to work on the Wio Terminal.
This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.
The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.
A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50b085ec83722106609f6fd219faf9f030 which used a timeout of
50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
I2C_POLL_DEFAULT_TIMEOUT_US.
This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.
