* 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.
Sample NXP P1021 Output:

- internal flash now mapped at 0xC0000000 (using `ARCH_FLASH_OFFSET`)
- wolfBoot binary included in internal flash (wolfboot partition is also
now writeable to test self-updates and encryption)
- sim test app supports encryption (sets the key for test)
- added new target to store the update in the external flash
- external flash mapped to 0xD0000000
move pcr reset and extend outside of session
the tpm uses policy checking for modifying PCR's so we need to reset and extend the PCR's with the image hash before the session begins, currently tested unseal, having trouble getting the simulator to run update in order to test reseal
- 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.
* 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.
* Cleanup execute bits on code files.
This commit introduces a simulated target where the internal and optionally the
external flash can be simulated and backed by files. Using this target will
produce an executable wolfBoot ELF image.
