19777: cpu/avr8_common: Prepare for rework ISR r=benpicco a=nandojve
### Contribution description
This prepares for rework how ISR is handled for AVR-8 platform. It is not expected changes on the behavior but tests on other boards were welcome to avoid regressions.
#### Improvements
* Split UART state from ISR states. Now it is necessary two variables and GPIORx registers are automatically selected when available.
* UART states now supports up to 8 UARTs.
* Added AVR8_ISR macro do clean-up and hide internals related to ISR processing. This allows changes on ISR without any other changes on drivers.
### Testing procedure
Tests were conducted using atmega328p-xplained-mini and atxmega-a1u-xpro and the zigduino board was only built. The example thread_duel was used to test regressions.

19804: cpu/nrf{53,9160}: add periph_rtt support r=benpicco a=dylad
### Contribution description
This PR enables support for `periph_rtt` on both nRF9160 and nRF53.
This PR is based on #19803
I was only able to test on nrf5340dk-app as I don't have access to any nrf9160-based board.
Here is `test/periph/rtt` output for reference on `nrf5340dk-app`:
### Testing procedure
flash `tests/periph/rtt` on `nrf9160dk` or `nrf5340dk-app` and check the results.

19807: boards/esp32s2-lilygo-ttgo-t8: fix display configuration r=benpicco a=gschorcht
### Contribution description
This PR fixes the display configuration for the ESP32-S2 LilyGO TTGO T8 (also known as LilyGo T-Display S2) which uses a ST7789 as display driver IC that is compatible with the ST7735.
For that purpose the ST7735 driver is extended by a pseudomodule definition `st7789` for the ST7789 which is enabled by the board and enables automatically the `st7789` (f57b6b70b8). Vise versa, board's `Makefile.dep` enables automatically the `st7789` pseudomodule if the `st7735` is used. The pseudomodule `st7789` is just used to increase the upper limit for supported lines.
### Testing procedure
```
BOARD=esp32s2-lilygo-ttgo-t8 make -C tests/drivers/st7735/ flash
```
should work:

19803: cpu/nrf5x_common: rework LFCLK source selection r=benpicco a=dylad
### Contribution description
This PR changes the source selection of LFCLK for all nRF families.
This idea is to use the values provided by Nordic vendor files to properly populate the source of the LFCLK. Then setup a per CPU check to ensure the value provided at board level is fine. In the end, the LFCLK source selection is a mere assignment.
The selection of the LFCLK source is still done at board level. I also add a bit of documentation to help users to select another value if needed.
I'll provide in a followup PR, `periph_rtt` support for both nRF9160 and nRF53.
### Testing procedure
CI should be enough I think. Otherwise, one can ran tests/periph/rtt on any nRF51-based board and any nRF52-based board.
You can also change the LFCLK source at board level to ensure the guards are doing their jobs.

The current ISR implementation for AVR8 requires use of
avr8_[enter/exit]_isr pair which add some boilerplate on code.
This add AVR8_ISR which clean-up the code and make it simpler
and hides any schedule detail from the user perspective.

Several STM32 families such as C0, G0, H7, L5 and U5 use `SYSTEM_STM32..XX_H` define instead of `__SYSTEM_STM32..XX_H` define to prevent multiple inclusion of `system_stm32xxxx.h`.
19733: cpu/msp430: reorganize code r=maribu a=maribu
### Contribution description
RIOT supports two distinct families of the MSP430: The [MSP430 x1xx] MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible MCU families the code was located in the msp430fxyz folder, resulting in case of the UART driver in particularly bizarre code looking roughly like this:
```C
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
```
This moves peripheral drivers shared between the two families to msp430_common and splits the SPI and UART driver into two MCU families.
In addition, it cleans up the `msp430_regs.h` by dropping most of it and using the macros and symbols provided by the vendor header files. There is little reason for us to maintain constants when TI is already doing that.

19769: cpu/nrf53: add initial support with nRF5340DK-APP board r=maribu a=dylad
### Contribution description
This PR adds support for nRF5340 MCU and its associated Nordic development board, nRF5340DK.
This MCU provides a dual Cortex-M33, one application core running at up to 128MHz, and one network core running at up to 64MHz.
Peripherals are inherited from others Nordic MCUs families so it shouldn't be hard to add more of them in followup PRs.
For now, only the minimal set of peripherals is supported:
- GPIO / GPIO_IRQ
- UART
- TIMER
### Testing procedure
Build the usual test application for the supported peripherals and flash the board.
nRF5340DK provides two serial ports on its embedded debugger. RIOT's shell should be available on the first one (/dev/ttyACM0)

The MSP430 vendor files already provide macros containing register
constants and symbols (provided via linker scripts) containing addresses
of peripheral registers. So lets make use of that rather than
maintaining a long list of constants.
The RNG can use HSI48, HSI48/2 or HSI16. Using MSI as 48 MHz clock source for RNG is not possible. The clock configuration in `stmclk_u5.c` activates anyway only the MSIS but not the MSIK which could be used for certain peripherals.
Therefore, this commit
- removes the configuration of MSI as 48 MHz clock for RNG and its selection in `RCC->CCIPR1.ICLKSEL`
- enables HSI48 and selects it for RNG.
The HSI48 will also be used in future for certain peripherals such as USB OTG FS and SDMMC.
19770: cpu/nrf5x_common: reset all available CC channels r=maribu a=dylad
### Contribution description
Properly reset all CC channels of a given timer at initialization (except the last one which seems to be used for capture only in the driver).
The issue with the previous code was that some CCs were not clear on some nRF52 MCUs.
For instance, nRF52840 has 4 CCs for its two first timers, then 6 CCs for all others.
nRF9160 and nRF5340 also have 6 CCs for all its timer peripherals.
Thus, loop through the reported number of channels and clear the associated register instead of hardcoding the first 3 CC channels.
### Testing procedure
CI should be enough I think.
### Issues/PRs references
None.
19773: cpu/nrf{52,9160}: remove duplicate sevonpend bit r=maribu a=dylad
### Contribution description
This PR removes duplicate calls of `SCB_SCR_SEVONPEND` bit in nRF52 and nRF9160.
This call is already done [here](7c320055a1/cpu/cortexm_common/cortexm_init.c (L60))
### Testing procedure
Flash a nRF52 or nRF9160-based board and check that the board is still alive.
### Issues/PRs references
None. I notice this duplicate call when porting nRF53.

Vera++ doesn't like `#error` preprocessor directives without a quoted
string afterwards (and also my syntax highlighter doesn't like this as
well). So let's add the quotes to have the tools not spooked out.
19712: cpu/riscv: Add PMP driver r=MrKevinWeiss a=Teufelchen1
### Contribution description
Hi! 🐘
this adds a basic RISC-V physical memory protection (PMP) driver to RIOT. Well, 'driver' might be a stretched, feels more like a little utility :)
EDIT: Also added a no-execute RAM option for the hifive & a corresponding test
Since I only have an Hifive rev b, it's only enabled on this board / cpu. I also tested the code on an ESP32-C but the feature can't be enabled there, as `cpu/riscv_common/` is not used by the ESP32...
### Testing procedure
* Grab a hifive rev b
* go to `examples/hello-world`
* Add `USEMODULES += periph_pmp` to the `Makefile`
* Include `pmp.h` in `main.c`
* Add code e.g. `print_pmpcfg(0);`
* compile & flash & term
You should see something like this:
```
# Hello World!
# You are running RIOT on a(n) hifive1b board.
# This board features a(n) fe310 MCU.
# pmp00cfg: - R-X OFF 0x00000000 - 0x00000000
```
