RE: Read MCUboot version from main app

Hello,

We use the "Firmware information" library to embed version information into the bootloader image, but this is usually only done when the bootloader is upgradable (i.e., when MCUBoot is used as the second stage bootloader), and the version is then being read by the first stage bootloader, not the application. Accessing the firmware information structure from the application running in the Non-secure Processing Environment may be more involved. Since the bootloader is immutable, I think it may make sense to always use the same bootloader hex when programming the devices in production.
