Architecture support for STMicroelectronics STM32L552xx and STM32L562xx
MCUs. This is based on corresponding code for STM32L4, but has been
considerably adjusted. Tested with Nucleo-L552ZE-Q and STM32L562E-DK
boards with simple NSH configurations.

Port C was not working because the GPIO pin count was
wrong. The 48 pin packages has 34 GPIO (Not counting PH0 & PH1)
It is GPIOA GPIO B (sans PB11) and GPIOC PC13-PC15
Summary:
- This commit introduces SP_WFE() and SP_SEV() to be used for spinlock
- Also, use wfe/sev instructions for ARMV7-A to reduce power consumption
Impact:
- ARMV7-a SMP only
Testing:
- sabre-6quad:smp (QEMU, dev board)
- maix-bit:smp, esp32-devkitc:smp, spresense:smp sim:smp (compile only)

arch/arm/src/stm32/hardware/stm32_spi.h:
* Avoid numerous ifdef on STM32 part numbers and make the
different variations of SPI peripheral features more
self-documenting: based on STM32_HAVE_IP_SPI_V* defines
from chip.h, define some or all of HAVE_SPI_I2S,
HAVE_SPI_TI_MODE, HAVE_SPI_ARB_DATA_SIZE, HAVE_SPI_FIFOS,
HAVE_SPI_NSSP, HAVE_SPI_I2S_ASTRT, and make decisions on
which registers and bitfields to define based on them.
* Define registers and bitfields for STM32_HAVE_IP_SPI_V4,
currently used only for STM32G47XX family MCUs, including
SPI_CR1_CRCL, SPI_CR2_NSSP, SPI_CR2_FRXTH, SPI_CR2_LDMARX,
SPI_CR2_LDMATX, SPI_CR2_DS_SHIFT/SPI_CR2_DS_MASK,
SPI_SR_FRLVL_SHIFT/SPI_SR_FRLVL_MASK, and
SPI_I2SCFGR_ASTRTEN.
* SPI_I2SCFGR_I2SSTD_PHILLIPS: Was defined incorrectly as
(xx << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to
(0 << SPI_I2SCFGR_I2SSTD_SHIFT).
* SPI_I2SCFGR_I2SSTD_MSB: Was defined incorrectly as
(0 << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to
(1 << SPI_I2SCFGR_I2SSTD_SHIFT).
* Fix nxstyle errors.
arch/arm/include/stm32/chip.h:

STM32F37XX, STM32F4XXX, STM32G47XX, and STM32L15XX.

- Add eMMC device
- Frame buffer support
- Fix SD/GNSS/sensor drivers not worked

The QuickFeather board added as an initial target.
These featrues are minimally implemented:
* Clock Configuration -- All clocking registers are defined and
configuration is used to setup the HSO, M4 Core, and M4 Perif
clocks. Additionally some clock debugging is stubbed for
bringing out clock paths to IO pins.
* UART -- The lowputc as well as the serial driver is implemnted
for the single UART device. Currently the configuration is
hard coded, but uses the proper interfaces to later fill in.
* SysTick -- The system tick timer is implemented and clocking
properly. Tickless mode is not yet implemented.
* Interrupts -- The interrupt system is implemented and verified
using the UART and SysTick systems.
* GPIO -- GPIO and IOMUX systems are defined and implemented.
This is verified using the UART as well as the Arch LED
system. The GPIO interupt system is stubbed out but not
implemented.
* Arch LEDS -- The blue LED as part of the RGB LED is configured
and attached to the Arch LED system. This indicates the device
coming online as well as when a hardfault is triggered.
Applications and Testing:
* There is a nsh configuration implemented that includes debug
features as well as the ostest, getprime, and mem test.
All of these have been run and verified.

Move the logic to get TLS information from an inline function to a normal function. For the unaligned case, it is probably too large to be inlined.
Also fixes some minor things from review of previous commits.
In a fit of confusion, I accidentally committed PR 879 before it passed its nxstyle check (it did pass all of its build tests, but not the style check). It was really my intention to merge PR878, but I screwed that up and merged 879 instead.
This PR makes amends by passing all of the .c and .h files modified by PR879 through nxstyle and correcting all reported style problems.
1. Add dsp extension; float point based on hardware and software.
2. Delete folder "iar"
3. Add tool chain for cortex-M23 and cortex-M35p

All parts in the STM32H7x3xx family have the same pinmap, etc.,
so extending support to all members of the family required only
minimal changes: Adding them to Kconfig, extending some
preprocessor logic, and minor code changes.
arch/arm/src/stm32h7/Kconfig:
* Add explicit support for all microcontrollers in the
STM32H7x3xx family by adding support for:
- STM32H743AG
- STM32H743AI
- STM32H743BG
- STM32H743BI
- STM32H743IG
- STM32H743II

- STM32H753AI
- STM32H753BI
- STM32H753VI
- STM32H753XI
- STM32H753ZI
* Fix TODO items for IO_CONFIG (all STM32H7X3XX).
* Because 100-pin parts lack GPIO ports F and G, but have
port H, create the new hidden configs STM32H7_HAVE_GPIOF
and STM32H7_HAVE_GPIOG.
* STM32H7_STM32H7X3XX:
- Select STM32H7_HAVE_GPIOF and STM32H7_HAVE_GPIOG only
when not STM32H7_IO_CONFIG_V (100-pin part).
- STM32H7_STM32H7X3XX: select STM32H7_HAVE_SPI5 for all
IO configs except V (100-pin part), which doesn't expose
SPI5 due to pin count.
* STM32H7_STM32H7X7XX: Always select STM32H7_HAVE_GPIOF and
STM32H7_HAVE_GPIOG because we aren't adding more part
numbers in this family.
* Remove extraneous (duplicate) "bool" and "default n"
lines.
* config STM32H7_FMC: Fix indent (contents were indented
with spaces while rest of file uses tabs).
arch/arm/include/stm32h7/chip.h:
* Extend preprocessor logic to add support for the new
MCU part numbers.
* Expand table of differences between family members.
* Define STM32H7_NGPIO based on IO_CONFIGs decided in Kconfig.
* If IO config is not known, issue compile-time #error
with grep-friendly "CONFIG_STM32H7_IO_CONFIG_x Not Set."

* Fix nxstyle complains (wrong end of line comment position

* g_gpiobase[]: Init base address for ports F and G according to
CONFIG_STM32H7_HAVE_GPIOF and CONFIG_STM32H7_HAVE_GPIOG.
* stm32_configgpio(): Replace complicated check with g_gpiobase[]
null check. Suggested by davids5.
* stm32_gpiowrite() and stm32_gpioread(): Add previously missing
null check of g_gpiobase[].
arch/arm/src/stm32h7/stm32_gpio.h:
* Wrap the defines GPIO_PORTA, GPIO_PORTB, GPIO_PORTC, GPIO_PORTD,
GPIO_PORTE, GPIO_PORTF, GPIO_PORTG, GPIO_PORTH, GPIO_PORTI,
GPIO_PORTJ, and GPIO_PORTK in conditional logic so that the
compiler will prevent use of ports that do not exist on the
target MCU.
* Fix nxstyle complaints.
Documentation/NuttX.html:
* Remove copy-and-pasted anchor for stm32f76xx77xx.
* Correct link to README.txt for Nucleo-H743ZI board,
formerly on BitBucket, now on GitHub.
* Add list item for STMicro STM32H747I-DISCO board.

This reverts commit f735584514.
These header changes introduce unacceptable errors:
1. The changes alter the width of the initial block comment. That will cause nxstyle failures on most of the files.
2. The third line of the header is an (optional) short description of content of the the file. This change erroneously removes that line.
Automated header file changes can screw up a lot of files, very quickly.
* SAMA5D27 peripheral support - USB Host working
- updated nsh defconfig with vfat for testing USB Host
- sama5d2_xult: USB Host worked.
- ported sam_bringup.c code from sama5d3-xplained
- USB 2.0 HS now working
- other perpherals may work, but haven't been tested
* update license headers to approve NuttX Apache-2.0
To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.

STM32L4_NUSART was set to 4. The spec at
https://www.st.com/resource/en/datasheet/stm32l433cc.pdf states the
following on page 1:
- 4x USARTs (ISO 7816, LIN, IrDA, modem)
- 1x LPUART (Stop 2 wake-up)
However it on page 49, it states:
The STM32L433xx devices have three embedded universal synchronous
receiver transmitters (USART1, USART2 and USART3).
The latter is correct.
This patch sets STM32L4_NUSART to 3.
