I know, but could I read out how a FPGA is programmed?
So when the hardwareproducer use a programmed FPGA inside a GNU/Linux
phone he has not to publish the VHDL code - right?

Sun published the sparc for free, right?
And on this CPU inside FPGA could run GNU/Linux again.

But when the v1 has a SPI connector, we could solder in a FPGA for
ourself - right? Are there FPGA with power mangement options - internal
timer to let the FPGA sleep for a while? Wake on signal?

Could FPGAs work with analog audio?
