Is that your only flash? It needs to be mapped at the top of mem
so it provides the 0xfffffffc address.

If flash is mapped at 0x0300000 then what does it read at 0xfffffffc?
I think the typical ref designs call for using BRAM up there to put your
boot code, but that may just be a waste to have it just jump to flash.
You might at well move flash up to the top of the mem map.
