Hi Andrew,
In Linux we have SMCCC v1.1 compliant HVC call arm_smccc_1_1_hvc(), which i=
s used for SMCCC and HVC call convention.
In FreeBSD do we have something similar?
I can arm_smccc_smc() in sys/dev/psci/smccc.h, but could not find the imple=
mentation details of it. If I need to use SMCCC compliant
HVC call, what API should I use?
Thanks & Regards,
Souradeep
