This is the normal configuration for building METRO M4 code.

---help---
|
|
During early bring-up, it is safer to execute entirely from
|
|
SRAM until you are confident in the initialization logic.
|
|
Then you can safely switch to FLASH.
|
|
|
|
REVISIT: This auto-selects CONFIG_BOOT_RUNFROMISRAM but I have
|
|
found, with some difficulty, that that choice still defaults to
|
|
CONFIG_BOOT_RUNFROMFLASH, causing link-time failures when running
|
|
from SRAM.
