This commit fixes#7857 and #7193 by saving Wi-Fi parameters and
set them at once, avoiding unknown behaviors of the Wi-Fi driver.
This commit also enables setting the auth of the STA/softAP modes
while connecting to/providing the wireless network.
RISCV has a modular instruction set. It's hard to define cpu-model to support all toolchain.
For Zig, cpu model is this formal: generic_rv[32|64][i][m][a][f][d][c]
For Rust, cpu model is this formal: riscv[32|64][i][m][a][f][d][c]
So, it's better to map the NuttX config to LLVM builtin cpu model, these models supported by
all LLVM based toolchain.
Refer to : https://github.com/llvm/llvm-project/blob/release/15.x/llvm/lib/Target/RISCV/RISCV.td
These models can't cover all implementation of RISCV, but it's enough for most cases.

This has been a long issue for me as it results in random crashes when
asynchronous events occur when the idle process is active.
The problem is that the kernel cannot access user memory, because the CPU
status prevents it.
Current Toolchain.defs set the compile flags directly, it's OK for
target specified gcc toolchain.
But some LLVM based toolchains (Rust/Zig etc) use single toolchain to handle all supported paltform.
In this patch, arch level Toolchain.defs export standard LLVM style arch flags, and let <Lang>.defs to map them into internal style,
This will simplify the intergration of non-c language.

arm-none-eabi-gcc 12.2.0 gives the following warnings:
error: 'primask' is used uninitialized
error: 'primask' may be used uninitialized
We use Werror and the file is indirectly included in different
places. I suggest telling the compiler to ignore these warnings
since primask is initialized on the first assembly line.
This is the only problem I encountered so far when upgrading the compiler.
SPI transfers are dynamically determined to use DMA or not.

This commit adds support for dead time delay to SAMv7 PWM driver. The
dead time can be used to delay an active PWM output at the begining
of the period. This can be used for H bridge control for example.
The values are to be set from the application level. It is required
to allow config option PWM_DEADTIME in order to support dead time delay.

Hardware flow control for serial requires the usage of DMAC channels
which is not yet supported for SAMv7 MCU. However the same config option
CONFIG_SERIAL_IFLOWCONTROL is also used for USB CDC/ACM flow control which
works well. Therefore the warning message should be raised only if

A list of breaking changes:
- SoftDevice libraries was renamed and libaries are now cmpatible with all platfroms with a given faimily.
- The random number generator was decoupled from the controller and must now be provided by the user.
We use arc4random_buf NuttX API for this.
- sdc_support_ API must be called before sdc_cfg_set()
- update public API terms to Bluetooth Core Specification v5.3 (mainly change slave/master to central/peripheral)
NuttX NRF52 configuration options properly updated.
- BLE features are supported only if the proper BLE role is selected
- sdc_hci_evt_get() and sdc_hci_data_get() have been replaced by sdc_hci_get()
If transfer is restarted in irq handler the interrupts shall be
cleared before the start bit is set in control register. This is
to avoid ints being accidentally cleared before they are handled leading
to timeout error.
In spi_irq handler the data is written into txfifo and transfer
is started before the TXDONE interrupt is cleared. If the bus/memory
access is in some cases delayed, the spi transfer may have been
finished already before the interrupt register is cleaned for the
transfer. This leads the early arrived interrupt to be just removed
and never handled, which would cause a timeout error.
This patch moves the clearing of the interrupt to the place before
the tx is started, so the interrupt is not missed in above cases.

VMPIDR_EL2 holds the value of the Virtualization Multiprocessor ID.
From architecture manual of AArch64, the behave is:
-reading register MPIDR_EL1 in EL2, it's return real MPIDR_EL1
-reading register MPIDR_EL1 in EL1, it's return VMPIDR_EL2
So since NuttX for SMP is running at EL1 to read MPIDR_EL1 for
identify CPU id, it's need to set VMPIDR_EL2 to MPIDR_EL1 for
every CPU at boot EL2 stage.
For some platform, the bootloader or hypervisor will do that at
the EL2 stage, but not all.

Summary:
The aarch64 have EL0~El3 execute level and NS/S (security state),
the NuttX should be execute at EL1 in NS(ARmv8-A) or S(ARmv8-R)
state. but booting NuttX have different ELs and state while with
different platform, if NuttX runing at wrong ELs or state it will
be not normal anymore. So we need to print something in arm64_head.S
to debug this situation.
Enabling this option will need to implement up_earlyserialinit and
up_lowputc functions just you see in qemu, if you not sure,
keeping the option disable.

Summary:
- I noticed that there are two kinds of descriptors for imxrt_enet.c
- The first one is the legacy descriptor and its size is 8bytes.
- The second one is the enhanced descriptor and its size is 32bytes.
- In both cases, we can not use a descriptor chain like stm32.
- Considering cache line alignment, the second one is perfect because
one descriptor fits the Cortex-M7 cache line which would fix networking
stability issues in d-cache write-back mode.

- imxrt ethernet in d-cache write-back mode

In the lower half UART driver for PIC32MZ architecture, adding the
TIOCxBRK ioctl calls, which allow an application to transmit a UART
line BREAK signal.
This architecture does not support BSD-style BREAK in hardware so our
implementation follows the precedent set in STM32, GD32, and Kinetis
architectures: By default, if only PIC32MZ_UART_BREAKS is configured,
we produce the hardware-native BREAK, which lasts for 12 bit lengths;
if, in addition, PIC32MZ_SERIALBRK_BSDCOMPAT is configured, we
generate a BSD-style BREAK by putting the TX pin in GPIO mode and
driving it low "manually" until told to stop.
* arch/mips/src/pic32mz/Kconfig
(config PIC32MZ_UART_BREAKS): New. Appears as
CONFIG_PIC32MZ_UART_BREAKS in code.
(config PIC32MZ_SERIALBRK_BSDCOMPAT): New. Appears as
CONFIG_PIC32MZ_SERIALBRK_BSDCOMPAT in code.
* arch/mips/src/pic32mz/hardware/pic32mz_pps.h
(__PPS_OUTPUT_REGADDR_TO_GPIO, PPS_OUTPUT_REGADDR_TO_GPIO): New
macros to automatically determine the GPIO port and pin from the
corresponding PPS (Peripheral Pin Select) define. Since there is a
one-to-one correspondence between PPS output mappings and a single
port and pin, these macros avoid writing redundant pin mappings. We
use this when switching the TX pin from UART to GPIO to generate
the BREAK and we could use it in other peripheral drivers in the
future to override hardware behavior.
* arch/mips/src/pic32mz/pic32mz_serial.c
(struct up_dev_s): Add new field 'brk' to indicate line break in
progress when built with PIC32MZ_UART_BREAKS. If generating BSD-
compatible BREAKs, also add tx_gpio, tx_pps_reg, and tx_pps_val, to
let us toggle the pin between UART and GPIO modes.
(up_ioctl): Add cases for TIOCSBRK and TIOCCBRK to turn BREAK on and
off, with both hardware-native and BSD-compatible implementations.
This is similar to the STM32F7 implementation.
(up_txint): Block enabling TX interrupt if line break in progress.
This is similar to the STM32F7 implementation.
Updating Simulator for macOS

Updating Changes to streamline with other Hosts
The PIC32MZ architecture provides a Peripheral Pin Select (PPS) which
allows mapping peripherals to different GPIO pins. To map a peripheral
output, a value is programmed to a register called RPnxR, where n is
the GPIO port (A thru K) and x is the GPIO pin (0 thru 15). The names
of these registers in code are PIC32MZ_RPnxR. However, in various
definitions, these were mistakenly written as PI32MZ_RPnxR (missing C
in PIC32). This prevents using any of the affected mappings. This
issue is fixed by repairing the define names.
* arch/mips/src/pic32mz/hardware/pic32mzec_pps.h,
arch/mips/src/pic32mz/hardware/pic32mzef_pps.h:
(): s/PI32MZ/PIC32MZ/g
The defines for Peripheral Pin Select (PPS) register RPE5R were called
RPE4R inadvertently; however, mappings elsewhere in the file used the
correct name of RPE5R, so the build would break if anyone attempted to
map those peripherals to GPIO pin E5. This issue is now fixed.
* arch/mips/src/pic32mz/hardware/pic32mzec_pps.h,
arch/mips/src/pic32mz/hardware/pic32mzef_pps.h:
(PIC32MZ_RPE4R_OFFSET): Rename to PIC32MZ_RPE5R_OFFSET.
(PIC32MZ_RPE4R): Rename to PIC32MZ_RPE5R.
When I checked how this register was set I discovered that 128 was not
accepted by the H7 but 64 was ok. Looking at the STM32Cube's HAL it
seems to be only 64 words long, however, the reference manual claims
otherwise.
I have opened a discussion on the ST community forum
https://community.st.com/s/question/0D73W000001nzqFSAQ
but unfortunately not received an answer yet.
In the meantime, I think, we should update this to what I found to be
working though.
