this is so i can track who contributed to this kernel fork
- CustomFirmwareDev - i2c dma fix, Prestigio PAP5500 DUO support
there's no upstream support OR they need some effort to make them working

non existent in the upstream
mostly useless i'd say, they're not full hw engines but rather only parts of the process. not worth the effort
not existent in the upstream
needs afe/i2s/etc drivers
it seems to be clock + reset controller for NAND and USB
EMI has performance monitoring + bw limiter
might be not worth the effort because it's pretty slow compared to software
bus violation monitor? not sure if we really need it, but should be pretty easy to port
downstrema calls it APARM_BASE and maps as infrasys? used for watchpoint and breakpoint
