This patch adds working integration of progmem FLASH. User can partition internal FLASH memory to up to 4 partitions and use any combination of raw, nxffs, smartfs and mtd_config filesystems (unless there are other limitations like nxffs supports only single instance). Support for dual CPU is added to Kconfig to not overwrite CPU2 program code. Code guards user to not allocate more memory than there is on FLASH, and warns user if not all FLASH memory is used. Errors will be printed when user tries to initialize two instances of nxffs or mtd_config filesystems. Signed-off-by: Michał Łyszczek <michal.lyszczek@bofc.pl>

All partition sizes are specified in PAGE_SIZE size. On

STM32WL5 page size is always 2048.

On STM32WL55JC there are 128 pages of flash memory. Size of

|
all configured partitions shall not exceed 128. In fact, it
|
|
should be equal to 128 or else you will simply have unused
|
|
space on flash. Even if you want some raw flash access you
|
|
should specify this partition in table and select fs_raw.
|
|
|

By default there are only 4 partitions defined, if you need
|
|
more, you can define more in Kconfig and stm32_flash.c files.

Partition will be used as smartfs. After first flash, you

command. This has to be done only once unless you change

partition table that would affect offsets and/or sizes.

Programmers (like openocd) should not touch this memory

when flashing new software, unless you exceeded reserved

memory for program code.

Smartfs uses quite substential ammount of FLASH data to
