utzig opened a new pull request #143: [RFC] Add basic multi-image support
URL: https://github.com/apache/mynewt-newtmgr/pull/143
 
 
   This makes `image list` and `image upload` compatible with MCUBoot's `serial_boot` when working in a multi-image setting.
   
   The image state CBOR packet and image upload were both update to carry an extra field called "image" whose number indicates which image set is being handled. If absent, image 0 is used for compatibility.
   
   The upload command got and extra parameter `-n` (or `--image`) to set which image is being sent, eg, `newtmgr image -n1 upload <fw.img>`.
   
   The image list command now prints "image=X slot=Y", eg:
   
   ```
   Images:
    image=0 slot=0
       version: 1.7.0.0
       bootable: false
       flags:
       hash: Unavailable
    image=0 slot=1
       version: 1.4.0.0
       bootable: false
       flags:
       hash: Unavailable
    image=1 slot=0
       version: 1.8.0.0
       bootable: false
       flags:
       hash: Unavailable
   Split status: N/A (0)
   ```
