This simplifies allocating outside of the VM because the VM doesn't
take up all remaining memory by default.
On ESP we delegate to the IDF for allocations. For all other ports,
we use TLSF to manage an outer "port" heap. The IDF uses TLSF
internally and we use their fork for the other ports.
This also removes the dynamic C stack sizing. It wasn't often used
and is not possible with a fixed outer heap.
Fixes#8512. Fixes#7334.
micropython puts the pointer-ness into the typedef; we can put the
const-ness there too.
this reduces the delta to micropython; for instance, emitinlinextensa
and emitinlinethumb now match upstream.
These are moved:
* Display -> busdisplay.BusDisplay
* FourWire -> fourwire.FourWire
* EPaperDisplay -> epaperdisplay.EPaperDisplay
* I2CDisplay -> i2cdisplaybus.I2CDisplayBus
`paralleldisplay` is now `paralleldisplaybus` (and registered as
`paralleldisplay` too).
Bus related helpers are split out of display_core into bus_core.
It is in still displayio since it is a dependency of both
busdisplay and epaperdisplay.
Fixes#7667
to trade compile speed & flash size
Initially enable the faster mode on rp2040 and espressif, where there's
usually plenty of flash available (these advanced techniques save hundreds
to thousands of bytes, which is important on a lot of old samd21 boards
but is a drop in the lake of a 4MB flash chip)
The error message for creating an I2S object on the rp2040 platform
in CircuitPython can be misleading when the word_select and data pins
are not sequential. This change updates the error message to provide
clearer guidance by specifying "GPIO pins" instead of just "pins".
The revised message now reads:
ValueError: Bit clock and word select must be sequential GPIO pins
Closes#8058

Currently on rp2 the time.time_ns() function has only seconds resolution.
This commit makes it have microsecond resolution, by using the output of
time_us_64() instead of the RTC.
Tested that it does not drift from the RTC over long periods of time.

This removes the duplicate code in cyw43, esp32, esp8266 that implements
the same logic as network.hostname.
Renames the `mod_network_hostname` (where we store the hostname value in
`.data`) to `mod_network_hostname_data` to make way for calling the shared
function `mod_network_hostname`.
And uses memcpy for mod_network_hostname_data, because the length of source
is already known and removes reliance on string data being null-terminated.

This changes from the previous limit of 15 characters. Although DHCP and
mDNS allow for up to 63, ESP32 and ESP8266 only allow 32, so this seems
like a reasonable limit to enforce across all ports (and avoids wasting the
additional memory).
Also clarifies that `MICROPY_PY_NETWORK_HOSTNAME_MAX_LEN` does not include
the null terminator (which was unclear before).

There is a single UART clock for all devices, so switching it for one will
affect all devices used at that time. This commit fixes that issue by
keeping the clock at a fixed value.
This fixed clock still supports the common baud rates between 300 and

support OTA rollback in the bootloader. These images can then be converted

While cyw43 is deinitialized, an interrupt occurs. That is handled with
these lines: ports/rp2/mpnetworkport.c#L59-L61 and as pendsv is disabled
while in network code, the poll function then just waits there.
When deinit has finished, the poll func is executed, but skipped:
src/cyw43_ctrl.c#L222-L225 this skips the `CYW43_POST_POLL_HOOK` which
would re-enable interrupts, but also reset `cyw43_has_pending`.
And in that state, the lightsleep code, will skip sleeping as it thinks
there is a network packet pending to be handled.
With this change applied, lightsleep works as expected when the wifi chip
is enabled, and when it's powered off.
Applies to newly-added ARDUINO_PORTENTA_C33 and UM_NANOS3.
