[meta-swupdate-boards][PATCH 0/1] Add support for STM32MP257F-EV1

[Dario Binacchi]

This patch adds support for the STM32MP257F-EV1 evaluation board.

Please note that this requires the recent changes submitted to both
SWUpdate core and meta-swupdate, which provide the handler and the
libfwumdata integration.

[Dario Binacchi]

The STM32MP257F-EV1 is an evaluation board based on the STM32MP25
microprocessor. More information can be found at:
https://www.st.com/en/evaluation-tools/stm32mp257f-ev1.html

Unlike other boards that typically rely on the U-Boot environment to
select the correct boot bank after an update, this board manages the
boot selection process through the Firmware Update (FWU) metadata
stored in dedicated partitions. This is achieved via the new fwumdata
script handler (CONFIG_FWUMDATA_HANDLER). Therefore, a version of
swupdate and meta-swupdate including this feature is required.

instead boots straight to Linux. U-boot is required to do the "swapping"
of partitions in the "dual-copy" layout.

+For usage with STMicroelectronics STM32MP one must add the following to
+`local.conf`:
+
+ SWUPDATE_IMAGES_NOAPPEND_MACHINE[core-image-full-cmdline]="0"
+ SWUPDATE_IMAGES_NOAPPEND_DISTRO[core-image-full-cmdline]="0"

+names to the image files.
