Implement support for swupdate, local updates
This commit adds support for updating the system using swupdate, using a dual root filesystem scheme: - genimage.cfg is updated to add another root filesystem partition, to implement the dual copy scheme - sw-description is the swupdate image description file, that will be part of the swupdate update file - postupdate.sh is the shell script that will be executed on the target once the upgrade has completed successfully. - gen-swupdate-image.sh is the shell script executed on the build machine at the end of the Buildroot build to generate the swupdate update file - extlinux.conf is updated so that the root= kernel argument is properly adjusted depending on which partition we are booting on - stm32mp15_dk_defconfig is updated with swupdate, the sgdisk tool from gptfdisk, and to call the gen-swupdate-image.sh script as a post-image script. - the kernel configuration is updated with additional options for USB mass storage support Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
