The customer wants to verify that a FPGA bitstream can be started properly
before saving the bitstream to the QSPI flash memory.
The customer sends the bitstream via FPGA framework and overlay, the
firmware will authenticate the bitstream but not program the bitstream to
device. If the authentication passes, the bitstream will be programmed into
QSPI flash and will be expected to boot without issues.
So when we have successfully reprogramed region with the
FPGA_MGR_BITSTREM_AUTHENTICATION flag, the bitstream in QSPI flash is
updated but not activated, we need an FPGA reboot to activate it, is it?
Correct. If the authentication passes, the bitstream will be programmed
into QSPI flash and will be expected to boot without issues.
Thanks,

Extend FPGA manager and region drivers to support the bitstream
authentication feature.
