* 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.
If the calculated header_sz is smaller than the value requested via
.config (or via IMAGE_HEADER_SIZE=x when compiling keytools), override
the value calculated with the preset.
Use generic buffer API to ensure that the files are open with the right
flags.
Non-POSIX systems would require `open()` to use an extra O_BINARY flag
to ensure the file is properly processed and sizes calculated
accordingly. As file descriptors are only needed in mmap() mode, the
win32 interface is reworked to use `fopen()` instead.
Thanks to Erik Chang for reporting this issue.
* Update documentation for signing with `--no-sign`, as the key argument should not be supplied.
* Recommend `make keysclean` instead of distclean on keys mismatch.
* Renesas headings/readme link and white-space.
* Fix issues with keygen tool import `-i` feature.
* Fix issue with key import incorrectly assuming key size.
* Add support for importing an ECC key with header.
* Fix for missing ECC key free.
* Refactor keygen tool to use utility function to get key size
* Fix to handle encoded ECC public keys when using `--sha-only` or manual sign
* Expanded the NXP QorIQ T2080 documentation in `docs/Targets.md`.
* T2080 fixes for boot code placement and generation of .bin.
* T2080 UART driver cleanup.
* Improve bin-assemble fill speed and report items added.
* Make portability fixes to enable building in `mingw32-make`.
* Cleanup the `docs/Targets.md` sections and links.
