[FEATURE] Allow building nxboot, miniboot or NuttX mcuboot on esp32 #17641
Description
Is your feature request related to a problem? Please describe.
Building nxboot, miniboot or the NuttX port of mcuboot fails on esp32 because int board_boot_image(const char *path, uint32_t hdr_size) is not implemented for esp32.
Describe the solution you'd like
Provide a int board_boot_image(const char *path, uint32_t hdr_size) for the different types of images that are supported by esp32 NuttX. This could be limited to the simpleboot and mcuboot image formats, and return -ENOTSUP for the legacy format.
When this functionality is provided it would remove the need to build the espressif port of mcuboot. It would also allow building miniboot, nxboot or other future bootloaders that are NuttX based. I have tried to distill such a functionality from the espressif port of mcuboot but I think that the there used solution is having some intrinsic limitations introduced by the hardware setup.
