During fallback operations, use a different encryption IV than the one
used to encrypt the backup during the update. This ensures that the same
IV is never reused to encrypt different sectors.
As reported by @reza-hdd in #589:
> When Firmware is large enough to consume all the allocated boot partition sectors, in the the final swap and erase operations (_wolfBoot_swap_and_final_erase_) the last sector of FW in Boot partition, which is used as a temporary sector for a copy operation, gets corrupted after being copied in external Swap partition and copied back. It looks like the contents are copied to the external Swap partition without being encrypted, but get decrypted when it is read back.
This was due to the function wolfBoot_copy_sector() assuming that all
copies having an external SWAP as destination would not need any
encryption, as the "normal" case during update is to copy already
encrypted sectors from UPDATE->SWAP.
In the final state, after the update is successfully applied, the
mechanism saves a copy of the last sector from BOOT->SWAP. In this case,
if the application is big enough, an extra function is needed to
encrypt the content of this last sector before writing it to SWAP.
Restoring the backup is OK (normal case SWAP->BOOT, decryption was
already there as also noted by the reporter).
- Support ELF scatter-loading on TC3xx
- Modify TC3xx HAL flash erase to support arbitrary offsets and sizes
- Realign partition size and addresses to support more efficient sector mass erase on update
