Pull Request Overview
This PR introduces support for ELF scatter-loading on external flash and integrates TC3xx support into the wolfBoot bootloader, while also adding DEBUG_UART functionality and updating related documentation.
- Refactors preprocessor macros for flash scatter-loading and adjusts flash writing logic in the TC3xx HAL.
- Adds buffered flash write and erase improvements along with DEBUG_UART support, including UART initialization and transmission.
- Updates firmware update and IDE documentation to reflect new ELF loading procedures and configuration changes.

@bigbrett please rebase to latest master to resolve conflicts, then assign to @billphipps for a final review on HW-specific components. |
- 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
