mfg command error

[vikrant-proxy]

I'm trying to use the mfg command with the following newt, and it's running into errors -

$ newt version
Apache Newt 1.10.0-dev / fd9df1e-dirty / 2021-05-17_16:21

I pulled a simple test app with the following details -

targets/nrf52_boot
  app=@mcuboot/boot/mynewt
  bsp=@apache-mynewt-core/hw/bsp/nordic_pca10040
  build_profile=optimized
targets/nrf52_blinky
  app=apps/blinky
  bsp=@apache-mynewt-core/hw/bsp/nordic_pca10040
  build_profile=debug

First complete build step for both targets

$ newt mfg create blinky 1
Error: failed to read manifest file: open <path-to-repo>/bin/targets/nrf52_boot/app/boot/mynewt/manifest.json: no such file or directory

My mfg.yml looks like this -

   mfg.targets:
       -
           name: 'targets/nrf52_boot'
           area: FLASH_AREA_BOOTLOADER
           offset: 0

       -
           name: 'targets/nrf52_blinky'
           area: FLASH_AREA_IMAGE_0
           offset: 0

   mfg.meta:
       area: FLASH_AREA_IMAGE_SCRATCH
       offset: 0

I believe this is because the bootloader binaries have now moved into @mcuboot folder, and newt cannot find them anymore.
