There are some sparse warnings in the HNS drivers:
warning: incorrect type in assignment (different address spaces)
expected void [noderef] <asn:2> *io_base
got void *vaddr
warning: cast removes address space '<asn:2>' of expression
[...]
Add __iomem and change all the u8 __iomem to void __iomem to
fix these kind of warnings.
warning: incorrect type in argument 1 (different address spaces)
expected void [noderef] <asn:2> *base
got unsigned char [usertype] *base_addr
warning: cast to restricted __le16
warning: incorrect type in assignment (different base types)
expected unsigned int [usertype] tbl_tcam_data_high

These variables used u32/u16 as their type, and finally as a
parameter of writel(), writel() will do the cpu_to_le32 coversion
so remove the little endian covert code to fix these kind of warnings.

According to the hip06 datasheet:
1.Six registers use wrong address:
RCB_COM_SF_CFG_INTMASK_RING
RCB_COM_SF_CFG_RING_STS
RCB_COM_SF_CFG_RING
RCB_COM_SF_CFG_INTMASK_BD
RCB_COM_SF_CFG_BD_RINT_STS
DSAF_INODE_VC1_IN_PKT_NUM_0_REG
2.The offset of DSAF_INODE_VC1_IN_PKT_NUM_0_REG should be
0x103C + 0x80 * all_chn_num
3.The offset to show the value of DSAF_INODE_IN_DATA_STP_DISC_0_REG
is wrong, so the value of DSAF_INODE_SW_VLAN_TAG_DISC_0_REG will be
overwrite
These registers are only used in "ethtool -d", so that did not cause ndev
to misfunction.

If there are packets in hardware when changing the speed
or duplex, it may cause hardware hang up.
This patch adds the code for waiting chip to clean the all
pkts(TX & RX) in chip when the driver uses the function named
"adjust link".
This patch cleans the pkts as follows:
1) close rx of chip, close tx of protocol stack.
2) wait rcb, ppe, mac to clean.
3) adjust link
4) open rx of chip, open tx of protocol stack.

There is a bug on Hip06 that tx ring interrupts packets count will be
clear when drivers send data to tx ring, so that the tx packets count
will never upgrade to packets line, and cause the interrupts engendered
was delayed.
Sometimes, it will cause sending performance lower than expected.
To fix this bug, we set tx ring interrupts packets line to 1 forever,
to avoid count clear. And set the gap time to 20us, to solve the problem
that too many interrupts engendered when packets line is 1.
This patch could advance the send performance on ARM from 6.6G to 9.37G
when an iperf send thread on ARM and an iperf send thread on X86 for XGE.

The use of ACCESS_ONCE() looks like a micro-optimization to force gcc to use
an indexed load for the register address, but it has an absolutely detrimental

This does not seem to happen any more with gcc-7, but removing the ACCESS_ONCE
seems safe anyway and it avoids a serious issue for some people. I have verified
that with gcc-5.3.1, the object code we get is better in the new version
both with and without CONFIG_KASAN, as we no longer allocate a 1344 byte
stack frame for hns_dsaf_get_regs() but otherwise have practically identical
object code.
With gcc-7.0.0, removing ACCESS_ONCE has no effect, the object code is already
good either way.
This patch is probably not urgent to get into 4.11 as only KASAN=y builds
with certain compilers are affected, but I still think it makes sense to
backport into older kernels.

In current scenario, when the interface is disabled we reset the XGMAC
RX/TX functionality. This operation does not affects the PHY layer/SFP
and which appears UP to the remote end(this behaviour is unlike GMAC).
The result is remote end keeps on sending the packets which gets partly
processed by XMAC and dropped. Since these are partly processed these
appears as errored packets in the packet counter statistics.
This patch fixes this behaviour and adds local-fault and remote-fault
functionality which can be used to intimate the remote peer whenever
the state of the interface changes. This patch also removes the
existing hns_dsaf_xge_core_srst_by_port function which was being used
to reset the RX/TX functionality at XGE Core.

In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network
Subsystem and is dependent upon DSAF module. Therefore, certain
functions like RESET are exposed through the common registers of
HNS DSAF module which are memory-mapped by the HNS driver and
currently can only be accessed through DT/syscon interface.
This patch adds the support of ACPI to the existing RoCE reset
function in the HNS driver(please refer NOTE 2). Hisilicon RoCE
driver (please refer NOTE 1) shall call this reset function during
probe time to reset the RoCE Engine.
The HNS Reset function indirectly ends up in calling the _DSM()
function part of the DSDT ACPI Table. Actual reset functionality
for ACPI is implemented within the ACPI DSDT Table which also has
been enhanced to support this change.
Support of ACPI in the HNS RoCE driver shall be pushed through a
different accompanying below patch:
"IB/hns: Add support of ACPI to the Hisilicon RoCE Driver"
NOTE 1: HNS RoCE driver has already been accepted by its maintainer
Doug Ledford<dledford@redhat.com>. Please refer below link:

This patchset adds support of Hisilicon Hip06 SoC to the existing HNS
ethernet driver.
The changes in the driver are mainly due to changes in the DMA
descriptor provided by the Hip06 ethernet hardware. These changes
need to co-exist with already present Hip05 DMA descriptor and its
operating functions. The decision to choose the correct type of DMA
descriptor is taken dynamically depending upon the version of the
hardware (i.e. V1/hip05 or V2/hip06, see already existing
hisilicon-hns-nic.txt binding file for detailed description). other
changes includes in SBM, DSAF and PPE modules as well. Changes
affecting the driver related to the newly added ethernet hardware
features in Hip06 would be added as separate patch over this and
subsequent patches.
