This patch introduces the direct execute-in-place (XIP) mode in addition to the other upgrade modes (swap strategies, overwrite-only). When direct-XIP is enabled with the MCUBOOT_DIRECT_XIP option, mcuboot selects the newest valid image based on the image version numbers from the image header, thereafter the selected image runs directly from its flash partition (slot) instead of moving it. Therefore the images must be linked to be executed from the given image slot. It means that in direct-XIP mode either of the primary and the secondary slots can hold the active image. This patch is based on the NO_SWAP upgrade strategy which was first introduced in the Trusted Firmware-M project. Source TF-M version: TF-Mv1.0.
