The general concept is described in Xilinx App Note 482:
http://www.xilinx.com/bvdocs/appnotes/xapp482.pdf
If your platform flash has enough room left over after the FPGA config,
then sure, there's no fundamental reason you couldn't put a uClinux
kernel image in there. Compression would help, but that will complicate
your bootloader since it will have to know how to decompress.
I don't know if the XUP board has much headroom in the platform flash
after the FPGA config, so it may not be possible on your specific board.
There may also be some requirements in how the platform flash device is
wired up - I don't know if the XUP board will support this mode of
operation.

The insertion of EDK apps into the bitstream is simply the
initialisation of the on-chip BRAM with the software object code. Linux
is much too big to fit into these BRAMs.

Read the Xilinx app note, it describes the process in detail.
