Jim Mussared 24a6e951ec ports: Simplify board feature tags in board.json.
This commit:
- Finds a common set of board feature tags and maps existing features to
  that reduced set.
- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).

This is to make the downloads page show a less intimidating set of filters.

Work done in conjunction with Matt Trentini <matt.trentini@gmail.com>.

Jim Mussared a377302623 extmod/modnetwork: Add network.hostname() and network.country().
This provides a standard interface to setting the global networking config
for all interfaces and interface types.

For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).

For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.

Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).

Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

robert-hh 5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
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.

robert-hh a0432ed9cb mimxrt: Update port to work with new nxp_driver v2.10.
The nxp_driver v2.10 allows for/requires some changes to the code:

- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
  library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI.  It's faster and interferes less with
  other modules.
- Use the clock_config.c files of library v2.8.5.  The mimxrt files keeps
  the clock_config.c files from Verson 2.8.5.  With clock_config.c from
  v2.10, the boards do not work.  Refactoring of the clock set-up is on the
  to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
  code.
- The clock_config.* files are moved from the board-specific directories to
  the boards directory and given a MCU related name.

robert-hh 1866ed7e2e mimxrt/eth: Add LAN support and integrate the network module.
This commit implements 10/100 Mbit Ethernet support in the mimxrt port.

The following boards are configured without ETH network:
- MIMXRT1010_EVK
- Teensy 4.0

The following boards are configured with ETH network:
- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK
- MIMXRT1064_EVK
- Teensy 4.1

Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.

Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works

The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.

Some boards do not wire the RESET and INT pin of the PHY transceiver.  For
operation, these are not required.  If they are defined, they will be used.

Philipp Ebensberger 7e62c9707a mimxrt/sdram: Add SDRAM support.
Adds support for SDRAM via `SEMC` peripheral. SDRAM support can be
enabled in the mpconfigboard.mk file by setting `MICROPY_HW_SDRAM_AVAIL`
to `1` and poviding the size of the RAM via `MICROPY_HW_FLASH_SIZE`.

When SDRAM support is enabled the whole SDRAM is currently used used
for MicroPython heap.

Philipp Ebensberger 0d7366c912 mimxrt: Rework flash configuration.
- Moves definition of BOARD_FLASH_SIZE and other header files related to
	flash configuration into the Makefile.
- Adds board specific clock_config.h.
- Adds board.h, pin_mux.h, and peripherals.h as they are
	required by NXP MCU SDK in order to use our own clock_config.h.
- Renames board specific FlexSPI configuration files.
- Updates flash frequency of MIMXRT1020_EVK
- Creates separated flash_config files for QSPI NOR and
	QSPI Hyper flash.
- Unifies VFS start address to be @ 1M for 1010 and 1020 boards.
- Unifies 1050EVK boards
- Adds support to both NOR and HyperFlash on boards with
	both capabilities.
- Adds automatic FlexRAM initialization to start-up code based on
	linker script and NXP HAL.
- Applies code formatting to all files in mimxrt port.

With this change the flash configuration is restructured and
organized. This simplifies the configuration process and
provides a better overview of each board's settings. With the integration
of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better
control of the settings and clock configurations. Furthermore the
implementation of an explicit FlexRAM setup improves the system
performance and allows for performance tuning.

Philipp Ebensberger 87f97e490c mimxrt/sdcard: Implement SDCard driver.
- Configures `PLL2->PFD0` with **198MHz** as base clock of
	`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
        to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!

SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.

robert-hh 1074c784b0 mimxrt: Add support for Hyperflash chips.
Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and
MIMXRT1064_EVK boards.

This commit includes:
- add support for Hyperflash
- modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to
  hyperflash.
- minor incidental changes to other boards so they still build

Note: Erasing a sector on the hyperflash is slow. It takes about a second,
which seems too long, but matches the data sheet.

robert-hh 98c5703027 mimxrt/machine_i2c: Add hardware-based machine.I2C to machine module.
It uses non-blocking transfer of data.  Advantage over SoftI2C:
- Higher data rate up to ~3 MHZ.
- Full protocol support.

robert-hh f45412793e mimxrt/machine_spi: Add the SPI class to the machine module.
This class supports SPI bus controller mode, with blocking transfers.

SPI device numbers start at 0, to comply with the pinout of the Teensy
boards.  With the configured clock frequency the fastest baud rate is
33MHz.  For messages longer 16 bytes DMA is used.  The class uses the
existing framework with extmod/machine_spi.c.

Extended driver options:

- drive=n with n being between 1 and 6 or PIN.POWER_1 to PIN.POWER_6.
  Since the pins used by the SPI are fixed, no Pin settings can be made.
  Thus the drive option is added allowing to control ringing and crosstalk
  on the connection.

- gap_ns=nnnnn is the time between sent data items in a frame given in ns.
  Default is 2 clock cycles.

robert-hh 689476c576 mimxrt/machine_uart: Add the UART class to the machine module.
The implementation uses the LPUARTx devices.  Up to 8 UARTs can be used,
given that the pins are accessible.  E.g. 8 on Teensy 4.1, 5 on
MIMXRT1020_EVK.

For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N.
The MIMXRT10xx-EVK boards have only one UART named, which gets the number
1.  All other UART are assigned to different Pins:

MIMXRT1010-EVK:
    D0/D1   UART 1
    D6/D7   UART 2
    A0/D4   UART 3

MIMXRT1020-EVK:
    D0/D1   UART 1
    D6/D9   UART 2
    D10/D12 UART 3
    D14/D15 UART 4
    A0/A1   UART 5

MIMXRT1050-EVK, MIMXRT1060-EVK, MIMXRT1064-EVK:
    D0/D1   UART 1
    D7/D6   UART 2
    D8/D9   UART 3
    A1/A0   UART 4

robert-hh dfd4324eb1 mimxrt: Add flash storage support with VFS and littlefs filesystem.
This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.

Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS.  VFS
  will take up most of the available flash. 1M is reserved for code.  9K is
  reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c.  All flashing
  related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
  module.

It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.

Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.
