Note: u-boot-spl is able to load the bitstream during boot. This is
very very similar functionally to FSBL.

AFAIK there is no support for this in meta-xilinx, since it brings in a huge dependency on Xilinx SDK which is not easy to package (nor possible due to licenses I think).

FSBL requires a newlib baremetal toolchain. So its technically
possible to build FSBL without the need for XSDK, however there would
be a large amount of work to get this working. Secondly the bootgen
tool is not available outside of XSDK so even if FSBL could be built
the other problem would be generating a BOOT.BIN image which has the
FSBL image tables and content. Since there is an (in my opinion,
superior) open source solution to this problem (u-boot-spl) there is
significantly less interest in having this support in meta-xilinx.

For reference the existence of the fsbl codebase which is grabbed as
part of the fsbl-platform-init recipe is how the ps7_init_gpl.[ch] is
grabbed for the zc702, zc706, etc. machines. This recipe will likely
disappear in the future as u-boot upstream now contains a version of
these ps7_init_gpl.[ch] files.
e.g. http://git.denx.de/?p=u-boot.git;a=tree;f=board/xilinx/zynq/ZC702_hw_platform;h=fde2238e18a5e8bf99d5eea0fbed5fa01399febd;hb=HEAD
