Can you elaborate what design aspects in the driver or anywhere else
should impose that limitation?
1. Oulijun resolved the problem, and sent PATCH V6 on 2016-4-28. Thanks for
more comments.
V6 still conditions things on ARM

2. This driver for Hisilicon RoCE Engine run in ARM SoCs.
The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoCs. HNS(Hisilicon Network Subsystem)
has a hardware support of performing RDMA with RoCE engine.
I understand that the HW is targeted just for ARM environments. Is
this the reason
why you want to impose this build limitation or there's something in
the driver design
or code that is not going to work in other environments?

This Kconfig related with this driver as below:

tristate "Hisilicon Hns ROCE Driver"
depends on ARM64 && HNS && HNS_DSAF && HNS_ENET
this is understood, my question came to better understand the limitations
