This patch adds some HW interfaces for bar operatioin interfaces,
including: mapped bar address geeting, HW attributes getting,
msi-x reg operation, function type getting and so on.

Micocode is named ucode in Hi1822. Its main responsibility is data
transmission and reception. But it can also handle some administration
works. It uses cmdq mechanism. This patch introduces data structures,
initialization, interfaces, and commands sending functions of cmdq.

Eqs include aeq and ceq. PMD supports aeq only. Aeq is a kind of
queue for mgmt asynchronous message and mgmt command response message.
This patch introduces data structures, initialization, and related
interfaces about aeq.

Mgmt module is a kinkd of administration module for the chip.
It is responsible for handling administration command from host.
It uses api channel. This patch adds related data structures,
packaged interfaces and function codes.

The items of configurations and queries for nic business include
MAC, VLAN, MTU, RSS and so on. These configurations and queries
are handled by mgmt module. This patch introduces related
data structures and function codes.

Work queue is used for cmdq and tx/rx buff description.
Nic business needs to configure cmdq context and txq/rxq
context. This patch adds data structures and function codes
for work queue and context.

OK for base file headers, but not if adding PMD header files in advance with a
commit is a good idea.
Can you please add those headers when they are used, it looks like
"hinic_pmd_ethdev.h" can be added on patch 11/15
"hinic_pmd_rx.h"/"hinic_pmd_tx.h" can be added on patch 12/15

Add build and doc files along with hinic_pmd_ethdev.c
which just includes PMD register and log initialization
for compilation.

+HINIC Poll Mode Driver
+======================
+
+The hinic PMD (librte_pmd_hinic) provides poll mode driver support
+for 25Gbps Huawei Intelligent PCIE Network Adapters based on the
+Huawei Ethernet Controller Hi1822.
+
+
+Features
+--------
+
+- Multi arch support: x86_64, ARMv8.
+- Multiple queues for TX and RX
+- Receiver Side Scaling (RSS)
+- MAC/VLAN filtering
+- Checksum offload
+- TSO offload
+- Promiscuous mode
+- Port hardware statistics
+- Link state information
+- Link flow control
+- Scattered and gather for TX and RX
+
+Prerequisites
+-------------
+
+- Learning about Huawei Hi1822 IN200 Series Intelligent NICs using
+ `<https://e.huawei.com/en/products/cloud-computing-dc/servers/pcie-ssd/in-card>`_.
+
+- Getting the latest product documents and software supports using
+ `<https://support.huawei.com/enterprise/en/intelligent-accelerator-components/in500-solution-pid-23507369>`_.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_HINIC_PMD`` (default ``y``)
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+Build with ICC is not supported yet.
+X86-32, Power8, ARMv7 and BSD are not supported yet.

+HINIC Poll Mode Driver
+======================
+
+The hinic PMD (librte_pmd_hinic) provides poll mode driver support
+for 25Gbps Huawei Intelligent PCIE Network Adapters based on the
+Huawei Ethernet Controller Hi1822.
+
+
+Features
+--------
+
+- Multi arch support: x86_64, ARMv8.
+- Multiple queues for TX and RX
+- Receiver Side Scaling (RSS)
+- MAC/VLAN filtering
+- Checksum offload
+- TSO offload
+- Promiscuous mode
+- Port hardware statistics
+- Link state information
+- Link flow control
+- Scattered and gather for TX and RX
+
+Prerequisites
+-------------
+
+- Learning about Huawei Hi1822 IN200 Series Intelligent NICs using
+ `<https://e.huawei.com/en/products/cloud-computing-dc/servers/pcie-ssd/in-card>`_.
+
+- Getting the latest product documents and software supports using
+ `<https://support.huawei.com/enterprise/en/intelligent-accelerator-components/in500-solution-pid-23507369>`_.
+
+- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following options can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_HINIC_PMD`` (default ``y``)
+
+Driver compilation and testing
+------------------------------
+
+Refer to the document :ref:`compiling and testing a PMD for a NIC <pmd_build_and_test>`
+for details.
+
+Limitations or Known issues
+---------------------------
+Build with ICC is not supported yet.
+X86-32, Power8, ARMv7 and BSD are not supported yet.

I am aware documentation says only arm64 and x86_64 are supported and default
config files default values implemented that way, still I believe it is safer to
not just assume it is either one or other.
What do you think explicitly check X86_64 too, as done for ARM64?

Hi Ferruh,
As you said, we just support arm64 and x86_64. First we determine arm64 using
"CONFIG_RTE_ARCH_ARM64" to define "__ARM64_NEON__" micro in Makefile.
If it has not defined "__ARM64_NEON__", it must be X86_64. This is our present situation.
I think we can use the same method to determine "X86_64" using "CONFIG_RTE_ARCH_X86_64".
If it is neither "ARM64" nor "X86_64", we can use "rte_be_to_cpu_32" and "rte_cpu_to_be_32".
How do you think about this?
Looking forward to your comments.
Thank you!
Best Regards,
Ziyang Xuan

Hi Ziyang,
I put a few minor comments on patches, other than those looks good.
Also can you please run "./devtools/check-git-log.sh", I think it will give some
warnings on commit log syntax, can you please check them?
Thanks,
ferruh
