the analog and digital 3.3v power have been wired together because it looks like there are components on the example schematic to sort out analog and digital power. however i don't know if that's ok

track down other ldos a SY8021L and also a LDO AP1231. create kicad parts, add them. make separate sheet for them. and it's a SOT-25 (SOT-23-5L) SY8021L isn't clear, datasheet not yet located, this part TD6821 is equivalent

find a good description of how to daisy-chain 4 DDR3 IC clock lines together, and annotate it correctly on the ddr3_flyby.sch page

select the GPIO pins from pinouts most suitable to go onto the PCMCIA interface.
