STM32F2 series flash layout is as follows:
{.pages_count = 4, .pages_size = KB(16)},
{.pages_count = 1, .pages_size = KB(64)},
{.pages_count = 7, .pages_size = KB(128)}
Since NVS subsys requires 2 sectors of max 32K in total, provide a
flash partition which respects this constraint using 2 of the 16K sectors
in the beginning of the layout.
Provide a compatible flash partition usable with mcuboot, but keep the
storage partition commented as its usage is not compatible with use w/o
mcuboot enabled (in this case main image starts as offset 0 which conflicts
with storage partition).
Note that it isn't possible either to get main image starting directly
in the 128K sectors w/o bootloader as boot flash address can't be
configured.

flash_copy() is performed on a page.size span but following flash_read() verification step is performed on EXPECTED_SIZE length (512). This doesn't work on devices where page.size is lower than EXPECTED_SIZE, such as STM32L1 where page size is 256. To fix this, perform verification on the smalest value between page.size and EXPECTED_SIZE. Signed-off-by: Erwan Gouriou <erwan.gouriou@st.com>
It's same test as "default", but more restrictive target wise. Signed-off-by: Erwan Gouriou <erwan.gouriou@st.com>

STM32 used to rely overlays in
samples/subsys/nvsto pass test.Now that nvs is used in a variety of tests (
tests/subsys/secure_storagefor instance) a more global approach is required.Draft for now while I'm passing the tests.
