STORE_SECTORS is a hard requirement. If there are fewer than 2 pages
then the kvstore will not work, because the garbage collection process
relies on having at least two sectors to work with.
STORE_PAGES is a heuristic. It is a reasonable default to use if the
application does not specify the amount of flash to use for TDBStore.
But if an application knows that a smaller number of pages will suffice
for its specific needs, then that is valid and should be permitted.
The minimum size required by tdbstore is either 2 sectors or 10 pages,
whichever is larger. Correspondingly, adjust the error checks in
_calculate_blocksize_match_tdbstore to match this requirement.
Default the size to the larger of two sectors or 10 pages, so that the
computation works better on devices with a low sector to page size ratio.
Reduce code duplication.
* Refactor some headers to use relative path from Mbed OS root.
* Refactor some data types to compile on 64bit machines.
* Refactor some debug traces to use mbed_trace.
To compile Mbed Bootloader with bare metal profile certain defines are
not added anymore automatically. Because of this checks for those
defines needed to be introduced.
Thus far the default position has been after the application plus two
spare sectors. For simplicity and to have a predictable location for the
TDBStore with the default configuration the location is now switched to
the end of the flash. Two last sectors to be exact.
To support block device out of mbed-os tree in KVStore, user needs to:
1. Configure blockdevice to "other".
2. Override get_other_blockdevice() to provide block device out of mbed-os tree.
remove of rbp_number_of_entries from the kvstore configuration. Adding default option for storage_type
allowing the system to choose TDB_INTERNAl, TDB_EXTERNAL or FILESYSTEM base on the blockdevice component
set in the target board. Adding remarks to kv_config.cpp and break simplify the _get_blockdevice_FLASHIAP function
- Consider data section in GCC_ARM toolchain
- Consider init_array section in IAR toolchain
- Rename macro to FLASHIAP_APP_ROM_END_ADDR for clarity sake
- Remove require integrity flag (authentication) - always authenticate
- Use RBP KV to store CMAC also in write once case
- Allow removing a key if reading it failed on RBP authentication error
- Disable SecureStore if user disables MBED TLS AES CTR or CMAC
