- Add per app flash storage
- Adds four data areas. An app can allocate an area. Once allocated
the area is tied to the CDI of the app and can only be
read/written/deallocated by the same app.
- Add two pre loaded app slots to flash
- Load an app from the first slot at boot. The app digest must match a
specific digest specified in firmware.
- Optionally load an app from the second slot
- Add a resetinfo area in FW_RAM which is used to signal an app's intent
of resetting the system and, optionally, pass data to firmware or the
next app in a bootchain.
