Hello Christian,
first of all, thanks for the review!

Will be contained in the v2. In the meantime:
RAM: NANYA NT5CC128M16JR-EK
NAND: Macronix MX30LF1G18AC-XKI

Thanks, will fix that.

It's 3 separate LEDs on the PCB, but they are directed to the same spot
on the case, so technically it works like a RGB LED.

You are right. I will alter this in v2 and prepare a patch to remove
this property from the 7530. Thanks for spotting this!

I can do that. In fact, the BDF from the 7530 is identical with a
reference boardfile (although this one has another chip-id). I only
noticed this while calculating the checksums for submitting.
