* Added initialization of the clocks and UART driver.
- wolfBoot uses on chip high speed oscillator (HOCO) at (120MHz RX65N and 240Mhz for RX72N).
* Added RX RSPI and QSPI driver support with external SPI flash
* Improve documentation and fix spelling errors.
* Added .srec (s-record) format support
* Added RX TSIP support for ECDSA (requires https://github.com/wolfSSL/wolfssl/pull/7685).
* Allow custom implementation of `get_trailer_at`, `set_trailer_at` and `set_partition_magic` using `CUSTOM_PARTITION_TRAILER`
* 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.
* Fixes for e500 L1/L2 cache.
* Fixes for eLBC and DDR3 drivers on P1021.
* Fixes for LAW and TLB for P1021.
* Fix for the e500v2 core peripheral issues with data barrier / coherency safety.
* Support for SP math all (`SPMATHALL=1`).
* Support for stage 1 loader (`make stage1`).
* HiFive1 HAL Support for PLL Clock, UART, RTC and Flash QSPI Erase/Write.
* HiFive1 update demo application for accepting firmware updates over UART.
* Added test-update-server application for pushing firmware image over UART.
* Fixes for building with `make SIGN=ECC256`.
* Improvements to wolfCrypt `user_settings.h`.
* General library cleanup (license headers and formatting)
* Updated the wolfSSL submodule to latest.
* Documentation updates including new `Targets.md` section for hardare instructions.
