[U-Boot] ZYNQ, ZC702 getting started

Hi,

i am currently starting development software for a new B&R board based on the ZYNQ7000.

To make live easier i want to try start with the Xilinx Evalboard ZC702, get there some experience to start afterwards with my own board.

I have allready built "zynq_zc702_defconfig" - but have no plan how to bring the build output to my board. Is it necessary to build some FSBL with the Xilinx SDK an merge the output with u-boot's output ? Or is it possible to take some SPL und U-Boot, burn it so SD-Card or QSPI flash and run ?

many thanks for help and best regards, Hannes
