What is QIXIS in the context of NXP boards?

[pibew84514]

While I was browsing through the u-boot sources and kernel drivers for ls1028ardb board I stumbled upon the term "QIXIS", also in the reference manual there is a chapter called "QIXIS programming model". The problem is that it's extremely difficult to find anything about it.

Correct me if I'm wrong - but is this just a defined set of register offsets shared across multiple NXP's boards equipped with FPGA so that they can just use a single driver to control FPGA available on e.g. ls1028 and e.g. ls21**? https://kodi.software/ https://dltutuapp.com/tutuapp-download/

Hello,

In reference to the LS1028ARDB, QIXIS is the system controller of the CPLD, it contains many registers which may be used to monitor and control both the processor and hardware on the RDB.
