oulijun e92f2c182b RDMA/hns: Configure TRRL field in hip08 RoCE device
The TRRL(Target RDMA Read/aTOMIC List) record the information
of receiving RDMA READ or ATOMIC operation in hip08. It will
be used the hardware. The driver need to assign a continuous
physical address for trrl_ba field of qp context.

Shaobo Xu 9766edc34e RDMA/hns: Split CQE from MTT in hip08
In hip08, the SQWQE/SGE/RQWQE and CQE have different hop num and
page size, so we need to manage the base address table of the
SQWQE/SGE/RQWQE and CQE separately.

This patch is to split CQE from MTT(SQWQE/SGE/RQWQE).

Wei Hu(Xavier) 13ca970e36 RDMA/hns: Modify assignment device variable to support both PCI device and platform device
In order to support the scalability of the hardware version, the
features irrelevant to the hardware will be located in the hns-roce.ko,
and the hardware relevant operations will be located in hns_roce_hw_v1.ko
or hns_roce_hw_v2.ko based on the series chips.

The hip08 RoCE engine is a PCI device, hip06 RoCE engine is a platform
device. In order to support both platform device and PCI device, We
replace &hr_dev->pdev->dev with hr_dev->dev in hns-roce.ko as belows:
	Before modification:
		struct device *dev = hr_dev->dev;
	After modification:
		struct device *dev = &hr_dev->pdev->dev;

	The related structure:
	struct hns_roce_dev {
		...
		struct platform_device  *pdev;
		struct pci_dev		*pci_dev;
		struct device		*dev;
		...
	}

Wei Hu(Xavier) 08805fdbeb RDMA/hns: Split hw v1 driver from hns roce driver
The hardware relevant definitions and operations are implemented
in hns_roce_hw_v* file. According to the diversity chips, the file
is named as hns_roce_hw_v1.c or hns_roce_hw_v2.c etc.

The general software process flow, common structures and allocated
algorithms are implemented in other files located in hns roce driver.

In order to support the scalability of the hardware version, the
common driver features are in the hns-roce.ko, and the hardware
relevant operations are in hns_roce_hw_v1.ko or hns_roce_hw_v2.ko
based on the series chips.

Artemy Kovalyov 3e7e1193e2 IB: Replace ib_umem page_size by page_shift
Size of pages are held by struct ib_umem in page_size field.

It is better to store it as an exponent, because page size by nature
is always power-of-two and used as a factor, divisor or ilog2's argument.

The conversion of page_size to be page_shift allows to have portable
code and avoid following error while compiling on ARM:

  ERROR: "__aeabi_uldivmod" [drivers/infiniband/core/ib_core.ko] undefined!

Wei Hu (Xavier) 5e6ff78a22 IB/hns: Change qpn allocation to round-robin mode.
When using CM to establish connections, qp number that was freed
just now will be rejected by ib core. To fix these problem, We
change qpn allocation to round-robin mode. We added the round-robin
mode for allocating resources using bitmap. We use round-robin mode
for qp number and non round-robing mode for other resources like
cq number, pd number etc.

Lijun Ou 7716809efe IB/hns: Add phy_port for computing GSI/QPN
This patch mainly adds phy_port to HNS RoCE QP. This shall be
used in calculating the GSI QPN for the port.
Initally when RDMA is being established, all IB ports share a
QPN which later needs to be re-assigned to a particular GSI/QPN
and which is per-port.
This also fixes a bug in base driver where iboe port was being
used instead of phy_port at some places. This values might not
be same always.
