The onboard flash used can contain up to 4 bitstreams for a 512 Mbit flash and up
to 8 for a 1Gbit flash, which is divided into equal 128Mbit regions. As standard a
512Mbit device is fitted. This is sufficient for two bitstreams for any size FPGA.
The SMT6002 software takes care about generating the correct offset/address while
writing bitstreams. The first bitstream should be stored at address 0x0 in the flash
and the second at address 0x200,0000, in order for the biggest/first bitstream to fit
without overlapping on the second bitstream.
