c8f19f1371 stm32/mboot: Make _estack an array to avoid compiler warnings.
The compiler can warn about out-of-bounds array access if _estack is just a
single uint8_t.

d43dd886a5 stm32/boards/NUCLEO_F413ZH: Remove STARTUP_FILE, it's defined globally.
The Makefile now defines this variable to the correct value (but it can
still be overridden by a board if necessary).

5fd62c8992 stm32: Remove SystemInit funcs, use stm32lib versions instead.
stm32lib now provides system_stm32XXxx.c source files for all MCU variants,
which includes SystemInit and prescaler tables.  Since these are quite
standard and don't need to be changed, switch to use them instead of custom
variants, making the start-up code cleaner.

The SystemInit code in stm32lib was checked and is equivalent to what is
removed from the stm32 port in this commit.

fa5c0b819c esp32/network_ppp: Add ppp_set_usepeerdns(pcb, 1) when init'ing iface.
Without this you often don't get any DNS server from your network provider.
Additionally, setting your own DNS _does not work_ without this option set
(which could be a bug in the PPP stack).

6b6403ce76 stm32/Makefile: Use startup_stm32*.s file from stm32lib.
This means that each MCU now gets a unique IRQ table, eg a specific one for
STM32F405, STM32F411, etc rather than just STM32F4xx.

3581deec81 stm32/boards/PYBD_SF2: Put mbedtls library code in external QSPI flash.
mbedtls is large and self contained so is a good candidate to be in
external XIP flash, to keep enough spare ROM in internal flash.

f88cb8a514 stm32/modmachine: Make RTC class available in machine module.
This is a start to make a more consistent machine.RTC class across ports.
The stm32 pyb.RTC class at least has the datetime() method which behaves
the same as esp8266 and esp32, and with this patch the ntptime.py script
now works with stm32.

c60caf1995 extmod/modlwip: Use mp_sched_schedule to schedule socket callbacks.
The helper function exec_user_callback executes within the context of an
lwIP C callback, and the user (Python) callback to be scheduled may want to
perform further TCP/IP actions, so the latter should be scheduled to run
outside the lwIP context (otherwise it's effectively a "hard IRQ" and such
callbacks have lots of restrictions).

1d6cb6357a extmod/modlwip: For TCP send keep trying tcp_write if it returns ERR_MEM
If tcp_write returns ERR_MEM then it's not a fatal error but instead means
the caller should retry the write later on (and this is what lwIP's netconn
API does).

This fixes problems where a TCP send would raise OSError(ENOMEM) in
situations where the TCP/IP stack is under heavy load.  See eg issues #1897
and #1971.

fa2c7ece8f extmod/modwebrepl: Make prompt/ver static arrays const to not use RAM.
The esp8266 lwip_open library is compiled with -mforce-l32 so these arrays

f114ce0a4b stm32/usb: Add "port" keyword argument to pyb.usb_mode, to select FS/HS.
If the board supports it, the USB port can now be explicitly specified, eg:

    pyb.usb_mode('VCP', port=0).

port=0 is USB FS and port=1 is USB HS.

46b3cc4572 stm32/usb: Add support to auto-detect USB interface, either FS or HS.
If both FS and HS USB peripherals are enabled for a board then the active
one used for the REPL will now be auto-detected, by checking to see if both
the DP and DM lines are actively pulled low.  By default the code falls
back to use MICROPY_HW_USB_MAIN_DEV if nothing can be detected.

caabdd99c0 stm32/qspi: Handle bus acquisition.
When going out of memory-mapped mode to do a control transfer to the QSPI
flash, the MPU settings must be changed to forbid access to the memory
mapped region.  And any ongoing transfer (eg memory mapped continuous read)
must be aborted.

8da39fd182 stm32/qspi: Use MPU to allow access to valid memory-mapped QSPI region.
The Cortex-M7 CPU will do speculative loads from any memory location that
is not explicitly forbidden.  This includes the QSPI memory-mapped region
starting at 0x90000000 and with size 256MiB.  Speculative loads to this
QSPI region may 1) interfere with the QSPI peripheral registers (eg the
address register) if the QSPI is not in memory-mapped mode; 2) attempt to
access data outside the configured size of the QSPI flash when it is in
memory-mapped mode.  Both of these scenarios will lead to issues with the
QSPI peripheral (eg Cortex bus lock up in scenario 2).

To prevent such speculative loads from interfering with the peripheral the
MPU is configured in this commit to restrict access to the QSPI mapped
region: when not memory mapped the entire region is forbidden; when memory
mapped only accesses to the valid flash size are permitted.

f3a5b313e5 py/nlrthumb: Check __thumb2__ instead of __ARM_ARCH_6M__.
This fixes compiling for older architectures (e.g. armv5tej).

According to [1], the limit of R0-R7 for the STR and LDR instructions is
tied to the Thumb instruction set and not any specific processor
architectures.
