The commit adds new API function flash_map with supporting flash_driver_api callback type. The new function is provided to allow accessing flash devices, in particular internal SoC flash devices, via processor address space. Signed-off-by: Dominik Ermel <dominik.ermel@nordicsemi.no>
Adds implementation for mmap callback for flash_driver_api. Signed-off-by: Dominik Ermel <dominik.ermel@nordicsemi.no>

Gray area, as does not require any work from other developers to existing code, even though changes flash driver api. |

I am marking this as DNM till I get some input from vendors of SoC devices. |
|
@de-nordic is it time to remove DNM? |
No. I will bring this into dev/arch meeting first. |
|
@mmahadevan108 @dleach02 Can you take a look in here? We have now issue in MCUboot mcu-tools/mcuboot#1661, that I have reported because people tried to hook flash_area_device_id and are now confused what that thing should return. |
