Here is output of mcuboot using stm board but I have question related to print starting bootloader, primary image, scratch, boot source, boot swap, where it is coming from means which file  for example king battle is print statement coming from main.c file . same related to above things.

"Starting Bootloader"
"Bootloader chainload" come from `v2.0.2\modules\tee\tfm-mcuboot\boot\zephyr\main.c`

"Primary image"
"Scratch"
"Boot source" come from `v2.0.2\modules\tee\tfm-mcuboot\boot\bootutil\src\swap_move.c`

"Swap type" comes from `v2.0.2\modules\tee\tfm-mcuboot\boot\bootutil\src\bootutil_misc.c`

You can find them easily in VS Code by using the Search tab and setting files to include to the SDK path

I got all except I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
I: Scratch: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3

`2.0.2\modules\tee\tfm-mcuboot\boot\bootutil\src` then depends on if it's a move or scratch
