And use these to initialize the LUT table properly for the various flash
types. The different flash types differ by 3 parameters. Thus it is
easier to just keep one copy of the qspiflash_config structure with the LUT
table and update it during flash initialisation as needed.

Allowing to use e.g. the Adafruit bootloaders with MicroPython. The .uf2
file is created in addition to the .bin and .hex files allowing to use the
latter ones without the bootloader for debugging and testing.
Changes:
- Set the location of the ISR Vector and .text segment to 0x6000C000 and
0x6000C400.
- Reserve an area at the start of ITCM for a copy of the interrupt vector
table and copy the table on reset to this place.
- Extend `machine.bootloader()` by setting the magic number to enable the
bootloader on reset.
- Create a .uf2 file which skips the segments below 0x6000C000.
The bootloader has to be installed as a preparation step using the board
specific methods, but then the firmware's .uf2 file version can be
installed using the bootloader. The bootloader can be invoked with:
- double reset
- calling machine.bootloader()
- Using the touch1200 method
Double reset is hard to achieve on MIMXRT boards, since there is no clean
reset pin. Some MIMXRT boards provide it by switching the power.
Some boards are excluded from the .uf2 build:
- MIMXRT1050_EVK: The uf2 bootloader is built for the QSPI version of the
board. MicroPython supports the Hyperflash version.
- MIMXRT1176_EVK: No support for this board yet, but it should be possible.

Supported triggers are: IRQ_RXIDLE and IRQ_TXIDLE.
When IRQ_RXIDLE is set, the handler will be called 3 character times after
the data in burst stopped.
When IRQ_TXIDLE is set, the handler will be called immediately after the
data has been sent.
This commit requires a change to fsl_lpuart.c, because the existing code
does not support under-run appropriately.
The irq.flags() value is cleared only at an expected event. Do not change
it otherwise.

Make can't handle paths with spaces, see https://savannah.gnu.org/bugs/?712
The following workarounds exist:
- When using make's built-in functions:
- Use relative paths wherever possible to avoid spaces in the first
place.
- All spaces in paths can be escaped with backslashes; quotes don't
work.
- Some users use the shell to temporarily rename directories, or to
create symlinks without spaces.
- When using make to pass commands to the system's shell, enclose paths in
quotes. While make will still interpret quoted strings with spaces as
multiple words, the system's shell will correctly parse the resulting
command.
This commit contains the following fixes:
- In ports/stm32/mboot/Makefile: Use relative paths to avoid spaces when
using built-in functions.
- In all other files: Use quotes to enclose paths when make is used to call
shell functions.
All changes have been tested with a directory containing spaces.

This is a code factoring to have the dict for the machine module in one
location, and all the ports use that same dict. The machine.soft_reset()
function implementation is also factored because it's the same for all
ports that did already implement it. Eventually more functions/bindings
can be factored.
All ports remain functionally the same, except:
- cc3200 port: gains soft_reset, mem8, mem16, mem32, Signal; loses POWER_ON
(which was a legacy constant, replaced long ago by PWRON_RESET)
- nrf port: gains Signal
- qemu-arm port: gains soft_reset
- unix port: gains soft_reset
- zephyr port: gains soft_reset, mem8, mem16, mem32

Minor change to remove support for using numeric IDs for machine.Pin. This
was previously based on the index of the pin in the board csv, but this is

All ports now use `--board-csv`, `--prefix`, `--output-souce`,
`--output-header` and no longer write to stdout. This matches the esp32
implementation.
Ports that have an AF input use `--af-csv` (to match `--board-csv`).
Any additional output files are now prefixed with `output-` (e.g.
`--output-af-const`).
Default arguments are removed (all makefiles should always specify all
arguments, using default values is likely an error).
Replaced the `af-defs-cmp-strings` and `hdr-obj-decls` args for stm32 with
just `mboot-mode`. Previously they were set on the regular build, now the
logic is reversed so mboot sets it.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. For all ports except the two listed
below there is no functional change.
The nrf port has UART.sendbreak() removed, but this method previously did
nothing.
The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

There are currently 7 ports that implement machine.WDT and a lot of code is
duplicated across these implementations. This commit factors the common
parts of all these implementations to a single location in
extmod/machine_wdt.c. This common code provides the top-level Python
bindings (class and method wrappers), and then each port implements the
back end specific to that port.
With this refactor the ports remain functionally the same except for:
- The esp8266 WDT constructor now takes keyword arguments, and accepts the
"timeout" argument but raises an exception if it's not the default value
(this port doesn't support changing the timeout).
- The mimxrt and samd ports now interpret the argument to WDT.timeout_ms()
as signed and if it's negative truncate it to the minimum timeout (rather
than it being unsigned and a negative value truncating to the maximum
timeout).

This is a basic SDIO driver for the mimxrt port, that was added mainly to
support the CYW43 WiFi driver, and as such it only supports the commands
required by the CYW43 driver (but more commands can be added easily). The
driver performs non-blocking DMA transfers, and can detect and recover from
errors.
Note: because the mimxrt port is missing static alternate functions, named
pins and other pin related functions, currently the alternate functions for
USDHC 1 and 2 are hard-coded in the driver.

If a board defines a custom bootloader entry function it will be called
first, if not and the ROM API supports RUN bootloader API, then
`machine.bootloader()` will jump to the ROM serial downloader in USB mode.
This allows:
$ make BOARD_DIR=path/to/board
to infer BOARD=board, rather than the previous behavior that required
additionally setting BOARD explicitly.
Also makes the same change for VARIANT_DIR -> VARIANT on Unix.

This drops the `.cpu` directive from the ARM gchelper_*.s files. Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`). The actual target CPU should be
determined by the compiler options.
The exact CPU doesn't actually matter, but rather the supported assembly
instruction set. So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.

The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.
The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
being the 1GB interface.
The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.
This work was done in collaboration with @alphaFred.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.
Make all extmod variables (src, flags, etc) private to extmod.mk.
Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.
Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

The new teensy loader keeps the file system under certain conditions:
- The file size is properly set in the file header.
- The header version is 4.3
These changes are implemented here, requiring a backport of
fsl_flexspi_nor_boot.c. There is still a problem with the command line
version of the teensy loader, which fails on the first attempt. At the
second attempt it works. The GUI version of the teensy loader is fine.
For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size. However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.
Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.
