Using `UART_DEV(0)` (UASRT1) for stdio allows to use the same TTL
adapter that is used for programming via `stm32flash` to be used for
serial, without re-wiring after flashing.
To control the compilation of NimBLE modules `nimble_*_ext` that require the Bluetooth 5 Advertising Extension, the `ble_adv_ext` is introduced to indicate that a platform supports this feature.
These BLE_* features are not necessarily nRF5x specific and should be defined as common features. The commit also fixes the alphabetical order for HAS_RUST_TARGET.
As per Section 5.2.1 of the MQTT-SN specification, the MQTT-SN length
header is either 1- or 3-octet long. If it is 3-octet long then the
first octet is 0x01. The asymcute implementation currently only checks
that the incoming packet is at least 2-octet long before attempting to
parse it (MIN_PKT_LEN). However, if the first octet is 0x01 the packet
must be more than 3 octet long in order to be valid. Since asymcute
does not check this it reads one octet beyond the packet data for a
2-octet packet where the first octet has the value 0x01. This commit
fixes this issue by adding an additional sanity check to _len_get.
Currently, asymcute only matches an MQTT-SN request to its
acknowledgement using the MsgId header. However, I strongly believe
this to be insufficient as asymcute would thus also match a SUBACK
to a prior PUBLISH message (for example) as long as the message ID
matches. To address this issue, this commit modifies _req_preprocess
to also compare the request message type in addition to the message id.
A single character type resulted in way fewer TX descriptors being
available than allocated. Not only resulted this in wasting memory,
but also when more iolist chunks than descriptors are send, the
```C
assert(iolist_count(iolist) <= ETH_TX_DESCRIPTOR_COUNT);
```
does not trigger. As a result, old TX descriptors are being overwritten
in this case.
The patches include the following changes:
- define ARRAY_SIZE in `component/spi_flash/spi_flash_timing_tuning.c` only if it is not yet defined by RIOT macros
- add alternative implementations for`spi_flash_disable_interrupts_caches_and_other_cpu` and `spi_flash_enable_interrupts_caches_and_other_cpu` if compiled for RIOT
- fix the undefined reference to `rtc_gpio_force_hold_en_all` in `components/driver/gpio.c`
- rename the bootloader patch to fix the serial number
Add the linker script for ESP32-S3 and modify the ESP32-C3 linker scripts to be compatible with them. The goal is to use a section list of objects that is common for all ESP32x SoCs in future.
