Can we have a symbolic link which can be hardcoded in intel_csr.c
and option will be given to user during installing the firmware
to create a symbolic link for the firmware wanted to load.
Want to avoid version number mentioned in firmware file name as it
getting change with latest fixes, bot not any API/inteface changes.
Agree as bxt and skl both are gen9 we can name as skl_dmc_gen9.bin
for now and discussion is going to finalize the name. Is it ok?
