To understand this correctly: Further up you have a way to determine the
state you're in, but then you only use that for debug printout, while
here where you should provide the status you say FPGA_MGR_STATE_UNKNOWN?

Am I missing something here?

This is more of a generic function ('What's the state of the FPGA now?') while
dump_status_reg() is invoked after a specific SPI command is sent to the FPGA to
keep track of the status of the chip and check that it adhere to the state
machine.

I'll send a v7.
