Subject: raw/cnxk_bphy: support reading NPA/SSO PF function
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f1704016db726f2de41a234f2936052b2b6a7637;p=dpdk.git

raw/cnxk_bphy: support reading NPA/SSO PF function

Add support for reading NPA/SSO pf_func which will be used
by a PSM to access NPA/SSO. PSM is a hardware block capable
of dispatching jobs to different blocks within a baseband
module.
