How to boot Zynq using separate bitstream?

I've always been following the standard petalinux flow to configure, build, package, and boot with BOOT.BIN and image.ub. I want to keep bitstream separate so that it can be easily updated without having to repackage BOOT.BIN, and I guess a good way to go is to download the bitstream in uboot. This doesn't seem to be an officially supported approach in petalinux as I didn't find such information in ug1144. Are there any instructions on how to configure petalinux project and uboot, if it needs to be modified manually, for this purpose?

I'm no expert in this, but I have read about dynamic reconfiguration. There might be a new name for it now. You might be able to boot with a minimal FPGA image and then have the Linux image (or MAYBE uBoot) to load a new image into the FPGA.

Thanks. I saw an instruction on using FPGA manager to download bitstream in Linux, but there are some limitations in my project so I definitely need to do that in u-boot. Haven't found any detailed documentation yet.
