repeatable steps so that power failure wont erase the encryption key and wont cause skipping the testing phase of boot. this is done by marking the update partition as final swap when erasing the final sector and backing up the key in boot sector 0 after swaping the real boot sector 0 to swap. then when a power failure occurs the encryption key will be available in either boot sector 0 or the normal location. the intermediate phase also prevents skipping the testing phase since the last sector, which holds the boot state, is erased and then set repeatably, since the final swap state is set on the update partition
* Added DDR4 w/ECC.
* Added L2 and L2 CPC SRAM support
* Added platform SRAM 160KB support
* Added support for core timers (timebase) and platform clock.
* Added IFC driver with erase/write
* Added stage 1 loader to relocate wolfBoot to DDR
* Added CPLD, QUICC, FMAN and MP drivers
* Added eSPI driver for TPM.
* Added hal_early_init instead of calling ddr_init directly.
* Fixes for device tree (DTB) loading with update_ram and PPC boot.
* Fixes for relocating CCSRBAR to upper.
* Fixes for interrupt offsets.
- non-secure flash area increased to cover BOOT+UPDATE partitions
- call unlock/lock functions before accessing pkcs11 store for writing
- Enabled more features in application wolfcrypt front-end
- Fixed compiler w4rnings
- Example with slots allocated at compile time
- Defining/allocating slots, provisioned as well as empty
- Checks for memory usage
- No free function for slots
* Added new `WOLFBOOT_TPM_SEAL` and `WOLFBOOT_TPM_SEAL_NV_BASE` config options.
* Added new `tools/tpm/policy_create` tool for assisting with creation of a policy digest. The sign keytool `--policy=file` signs the policy.
* Added new `WOLFBOOT_TPM_VERIFY` option to enable offloading of the asymmetric verification to the TPM. By default wolfCrypt will be used.
* Added example seal/unseal to update_flash for ARCH_SIM.
* Renamed `WOLFBOOT_TPM_KEYSTORE_NV_INDEX` to `WOLFBOOT_TPM_KEYSTORE_NV_BASE` to support multiple public keys.
* Refactored most TPM code into tpm.c.
* Refactored the keystore ROT to use new `wolfBoot_check_rot` API.
* Refactored the sign keytool to have a sign_digest function to allow signing firmware and policy for sealing/unsealing.
* Fix for make distclean && make using the wrong key tools.
