Since the recent PS4 Syscon Tools release comes PS4 Wee Tools for NOR and Syscon manipulations by AndyManDev on Twitter for those in the PlayStation 4 Scene working with PS4 NOR and Syscon dumps. 
Download: PS4 Wee Tools (Latest Version) / GIT / Wiki / PS4 EAP EMC Torus GIT / PS4 IC FW GIT (PS4 Southbridge/Torus firmware collection) / UART Pinout for PS4 Motherboard Models
Here's further details from the README.md: PS4 Wee Tools
PS4 wee tools help to work with PS4 nor and syscon dumps.
It is free open source alternative for @BwE's PS4-NOR-Validator & Syscon-Patcher written in Python to keep it simple.
Currently it provides base functional and can not fully replace those tools.
Was tested with Python 3.8
