Pull request overview
This PR adds external flash support and dual-bank flash swap functionality for PSoC6 devices, along with enhanced flash programming capabilities using a read-modify-erase-write approach.
Changes:
- Removed NVM_FLASH_WRITEONCE restriction to enable flexible flash programming
- Added external QSPI flash support with SFDP-based configuration and temporary sector management
- Implemented dual-bank flash swap for hardware-assisted firmware updates
- Enhanced internal flash operations with optimized erase size selection (sector/subsector/row)

Thanks for this contribution! A couple of minor things:
- check the return value of
ext_flash_read()as described indocs/HAL.md - it looks like the content of the temp sector is never restored at the end of
ext_flash_write()
