* 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:

* 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`).
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.
