- img_size: use 32-bit variable
- remove '+1' from pa_start calculation
- fix broken delta.c wb_diff check for distance between matching
patterns (root cause for the delta+encrypt bug)
leave the encryption key for wolfBoot_success to erase.
FINAL_SWAP was also stopping the case where the partition was put into testing before the update sector status flags could be erased. now, don't erase the update sector flags. instead put the update partition in IMG_STATE_FINAL_FLAGS state before putting the boot partition in IMG_STATE_TESTING. Then only erase the update sector flags on wolfBoot_update_trigger. under this scheme, the sector flags are intact if the power failed before we could set IMG_STATE_TESTING but are wiped if we do need to swap over after after wolfBoot_success fails to be called
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

* 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.
* Added TPM SPI wait state support and debug logging.
* Added platform auth ownership (change platform password to random value before boot). Can be disabled using `WOLFBOOT_TPM_NO_CHG_PLAT_AUTH`.
* Added parameter encryption support.
* Added TPM based root of trust based on https://github.com/wolfSSL/wolfTPM/pull/276
* Removed the TPM hashing feature (not practical).
* Fixed RSA with wolfTPM build.
* Fixed cleanup wolfTPM objects on make clean.
* Added simulator support for Mac.
* Fix for simulator to properly assemble wolfboot.bin + signedtestapp + update + swap.
* Fixes for handling 64-bit assigned mmap virtual addresses. Added hal_flash_write and hal_flash_erase support for 64-bit address using uintptr_t. Enabled if platform is 64-bit and `FORCE_32BIT` is not defined
* Fix simulator conflict with src/libwolfboot.o object in test-app.
* Cleanup test-app linker flags.
* Fix and refactor the L2SRAM support and use it for stage 1 loader stack.
* Fix NXP eSPI driver to support all sizes and properly handle keeping CS active.
* 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.
* Added ELF32 and ELF64 loader support (config `ELF=1` or build option `WOLFBOOT_ELF`).
* Add ELF support to `update_ram.c` loader.
* Add support for loading entire flash image to RAM when `EXT_FLASH=1` and `NO_XIP=1` (or `WOLFBOOT_USE_RAMBOOT`).
* Added QUICC Engine support to load microcode and enable.
* Add multiple core support for NXP P1021.
* Fixes to resolve first stage boot ROM relocation.
- Implemented temporary workaround to resolve stack traps.
* Added PPC GOT relocation support.
* Fix for the PPC `isr_empty` handler address.
* Fix to allow stack to use DDR by having assembly setup DDR TLB. After relocating wolfBoot use stack on DDR.
* Cleanup wolfBoot output.
- Only remove extra .bin/.elf created unless `make distclean` is used.
- Don't output the key grep test (only check result).
- Adjust build order (first stage, wolfboot, test app, key, sign test app and factory).
- Fix to make sure linker script is rebuilt before objects.

this update uses the tpm to retreive the public key used to validate the image that will boot and restricts access to that key by tpm policy. when the image is updated it's signature is used to extend the PCR and when the image is loaded it's signature must match what was sealed in order to get the public key from the tpm. enabling this option is done by setting WOLFBOOT_TPM_KEYSTORE in .config
- Using two sectors to keep partition/sector flags
- Keep two redundant set of flags, update one at a time
- Erase is done when the sector is old
- Flags update is faster because Erase is done in advance
- Accessing trailer information (including encryption keys) is done by
selecting the newest information
Tested via renode, using nrf52 with NVM_FLASH_WRITEONCE flag on.
