CM0/CM0+ processors have a maximum of 48 vectors; this allows the AppInfo_t block to reside at byte offset 192.

CM7 processors have a maximum of 256 vectors; STM32H7 processors are limited in practice to fewer than 200. So we need find the AppInfo_t block at various locations, depending on the target:

  • cm0+ at 192
  • stm32h7 at 960
  • generic cm7 (not stm32h7) at 1024

mccibootloader_image should look at various offsets automatically, and use the one that's found (rather than looking at offset 192 as in v0.4.0).
