Switches flash_sync to use stream_flash_erase_to_append instead of stream_flash_erase_page in preparation of deprecating the later and reming control on erase from API user. Signed-off-by: Dominik Ermel <dominik.ermel@nordicsemi.no>

|
|
Runs simple check to find whether provided device can be used for
|
|
stream flash by verifying that buffer size will fit into page.
|
|
Once correct configuration has been established and tested it is
|
|
worth to disable the option to cut out some unneeded code.

Enable callback that will be invoked once data is synchronized from
|
|
stream to device. When callback is not used, disabling the option
|
|
allows to save some code storage and RAM.

If disabled an external actor must erase the flash area being written

|
|
This is used in stream flash code to exclude invocation of erase on devices that do not
|
|
have such requirement prior to write nor support rase as a way to increase write speed.
|
|
Option is available only if there is a mix of devices, in a configuration, where some
|
|
support erase and some do not. If user is sure to not use Stream Flash with devices that
|
|
have no support for erase, this option may be disabled to discard small amount of code
|
|
from final application.

Enable API for loading and storing the current write progress to flash
|
|
using the settings subsystem. In case of power failure or device
|
|
reset, the API can be used to resume writing from the latest state.
