Sure, I'll split them into multiple libraries. What's the benefit of
then merging them back into a library of everything?

Fab. I was in general trying to keep the components similar to the
existing gta02 models, to minimise transposition mistakes when we're
re-creating the schematics. That leads me to a question about the CPU -
you mentioned doing that as multi-part, but I wasn't sure how much it
makes sense to break it up. There seems to be potentially 19 discrete
Memory, SDRAM, NAND, DMA
UART, SPI, SDIO, USB, JTAG, EINT, EINT+, IIC, IIS, ADC/TSP
LCD, Camera, Clock, Timer
Does it make more sense to have a 'part' for each of those 19, group
them as I have (mem, IO, peripherals, power), or do something
different? Is there value in re-creating the part exactly as it's drawn
in the current GTA02 schematics to minimise silly copying errors?
