Allocate a static tmpbuf instead of calling malloc. This is the only direct call to malloc in the code.
Create a small Makefile for the Zephyr build system to use.
Add support for building mcuboot as a Zephyr application. This is copied from the iotboot repo with some minor reorganization to work with the mcuboot directory layout.

MCUBoot multi image support mode requires each image be procedded individually that requires multiple signature check during boot. If there be 4 image it will require 4 times signature validatation. This feature increase boot time and depend on the project long boot time may not be expected. To provide a solution for this case we propose to - Generate each image as regular - Concatanate them and re generate a main mcuboot image. ------------------------- | Header | ------------------------- | SubImage (optional) | | (Header+Data+Footer) | ------------------------- | SubImage (optional) | | (Header+Data+Footer) | ------------------------- | ..... | ------------------------- | Footer | ------------------------- During boot time if top level image be validated sub image can be just copied to the target location without to recheck them. To provide this feature there will be two commit 1- Provide a script that combine images 2- Update mcuboot source code to process subimages This commit is for mcu-tools#1, in this commit we are adding a script which called as combine_images.py. The usage of the script is: python combine_images.py --config combine_images.yaml --imgtool imgtool --output <outfolder> combine_images.yaml file is added as reference file it need to be updated as per of the project need.

MCUBoot multi image support mode requires each image be procedded individually that requires multiple signature check during boot. If there be 4 imageis it requires 4 times signature validatation. This feature increase boot time. Depend on the project requirement long boot time may not be accepted. To provide a solution for this case we propose to - Generate each image as regular mcuboot format - Concatanate them and re generate a main mcuboot image. As below ------------------------- | Header | ------------------------- | Image-1 | | (Header+Data+Footer) | ------------------------- | Image-2 | | (Header+Data+Footer) | ------------------------- | ..... | ------------------------- | Footer | ------------------------- During boot time if top level image be validated sub image can be just copied to the target location without to recheck them. There will be two commit to implement this feature 1- Add a script that combine images 2- Update mcuboot source code to process subimages This commit is for mcu-tools#1, it adds a script which called as combine_images.py. Any imgtool parameters can be passed to the script It will directly pass them to the imgtool. Usage: python combine_images.py --config combine_images.yaml --imgtool imgtool --output <outfolder> combine_images.yaml file is added as reference file it need to be updated as per of the project need.
