e43a74a4db drivers/memory/spiflash: Add MICROPY_HW_SPIFLASH_ENABLE_CACHE option.
This only needs to be enabled if a board uses FAT FS on external SPI flash.
When disabled (and using external SPI flash) 4k of RAM can be saved.

2b9900380a stm32/boards/STM32F769DISC: Use macro instead of const for flash size.
So that the flash size can be changed in just one place.  Also remove the
duplicate cache entry.

96a4435be1 stm32/boards/STM32F769DISC: Add config to use external SPI as filesys.
This board now has the following 3 build configurations:
- mboot + external QSPI in XIP mode + internal filesystem
- mboot + external QSPI with filesystem (the default)
- no mboot + external QSPI with filesystem

c8c37ca407 stm32/boards/STM32F769DISC: Fix number of SDRAM row bits.
According to the schematic, the SDRAM part on this board is a
MT48LC4M32B2B5-6A, with "Row addressing 4K A[11:0]" (per datasheet).  This
commit updates mpconfigboard.h from 13 to 12 to match.

9670b26526 stm32: Rename MICROPY_HW_HAS_SDCARD to MICROPY_HW_ENABLE_SDCARD.
For consistency with the majority of other MICROPY_HW_ENABLE_xxx macros.

84479569de stm32/boards/STM32F769DISC: Use external QSPI flash to store some code.
This demonstrates how to use external QSPI flash in XIP (execute in place)
mode.  The default configuration has all extmod/ code placed into external
QSPI flash, but other code can easily be put there by modifying the custom
f769_qspi.ld script.

338635ccc6 stm32/main: Add configuration macros for board to set heap start/end.
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).

As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot.  On boards with SDRAM enabled the heap
has been set to use that.

a7ebac2eae stm32/can: Allow CAN pins to be configured per board.
This patch allows a given board to configure which pins are used for the
CAN peripherals, in a similar way to all the other bus peripherals (I2C,
UART, SPI).  To enable CAN on a board the mpconfigboard.h file should
define (for example):

    #define MICROPY_HW_CAN1_TX (pin_B9)
    #define MICROPY_HW_CAN1_RX (pin_B8)
    #define MICROPY_HW_CAN2_TX (pin_B13)
    #define MICROPY_HW_CAN2_RX (pin_B12)

And the board config file should no longer define MICROPY_HW_ENABLE_CAN.

02f88cb2df stm32/boards: Remove all config options that are set to defaults.
mpconfigboard_common.h now sets the defaults so there is no longer a need
to explicitly list all configuration options in a board's mpconfigboard.h
file.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
