I use the zc702 BSP with a 7z045ffg676 part. I have some code from Ric 
at SLAC for networking and the SD card which is working well. The SD 
code currently contains some GPL parts which need to be removed and 
while our use is "in house" this is ok.

Ric's code is based around the Xilinx BSP code from their SDK and I am 
looking to work with Xilinx via our FAE to see what we do. It might be 
we borrow the pieces of the code we need and create a suitable driver.

I use a hacked OpenOCD with the Zynq using a Flyswatter2 pod and this 
works fine. There are times where the JTAG link breaks down and cannot 
be recovered. It is good enough to debug and run the RTEMS testsuite. I 
would like to get a more recent OpenOCD and update but I do not have the 
time.

I do not use uboot, rather we have a taken the Xilinx FSBL and reworked it.

I would like to do a write up of the whole process but it is not a 
priority for my unfunded work.
