A lot of u-boots I've found point to a ramdisk filesystem instead of a partition.

That option should be pulled in from the devicetree, at least for sane u-boots! The one I linked appears to be a sane u-boot.

Hey, if it loads the kernel and FPGA it does everything I need it to do. The linked one is used in ADI's FMCOMMS distro and loads an FPGA image before the kernel boots, if you put the bitfile into the compiled boot.bin created by the Xilinx SDK.

Is there anything a newer u-boot buys me? If so I'll go through the legwork of rebuilding from recent sources. If not I'll keep on keepin' on. ;)

Not trying to do anything fancy; just trying to reproduce Jonathan Pendlum's FFT filter example, which was written back when that ancient stuff was current. I think it'd be good for that to be updated for people who want to run GNU Radio on Zynq. I know RFNoC will change how that's done with E310, but we don't need RFNoC for MicroZed/ZedBoard/ZC70x. I'm happy to help with the writeup if/when I figure all this out.

I'll try your newer image.
