[PATCH v10 00/22] Add HiSilicon RoCE driver

[Lijun Ou]

The HiSilicon Network Substem is a long term evolution IP which is
supposed to be used in HiSilicon ICT SoCs. HNS (HiSilicon Network
Sybsystem) also has a hardware support of performing RDMA with
RoCEE.
The driver for HiSilicon RoCEE(RoCE Engine) is a platform driver and
will support mulitple versions of SOCs in future. This version of driver
is meant to support Hip06 SoC(which confirms to RoCEv1 hardware
specifications).

Changes v9 -> v10:
1. delete redundant lines which it is netdevice.h in hns_roce_main.c
2. adjust the indentation for HNS_ROCE_V1_NUM_ASYNC_EQE
3. simplify the lines in hns_roce_init_qp_table function
4. add static type for hns_roce_unregister_device
5. move the call with hns_roce_unregister_device from the tenth patch to
   the eleventh patch in hns_roce_remove function
6. readjuest the alphabetic order in MAINTAINERS
7. redesigned the way for getting irq names
8. avoid the memory leakage because mr->pbl is not free in
   hns_roce_mr function
9. avoid the memory leakage because not kfree table->icm when exception
10. add the link from LKML as well whose comment in all

Changes v8 -> v9:
1. delete the definition of ADDR_SHIFT_n, use literal 12, 32 and 44 and
   add comments
2. use roce_read/roce_write/readl/write instead of roce_readl/roce_writel
3. delete the print error/debug messages for memory allocation errors
4. use exit instead of uninit, for example hw->uninit -> hw->exit
5. use roce_raw_write instead of _raw_writel in eq_set_cons_index
6. modify the label with underscore
7. adjust the indentation for the macro definitions in hns_roce_hw_v1.c
8. simplify some lines in few functions and structures
9. adjust the alphabetic order in MAINTAINERS

Changes v7 -> v8:
1. add a verbs operation named get_port_immutable. It is an 
   independent patch
2. add a comment for the definition of ADDR_SHIFT_n, n are 12,32
   and 44
3. restructures the code to align with naming convention of the Linux
   according to the review of Doug Ledford
4. modify the state for all .c and .h files

Changes v6 -> v7:
1. modify some type of parameter, use bool replace the original type
2. add the Signed-off-by signatures in the first patch
3. delete the improper print sentence in hns_roce_create_eq.

Changes v5 -> v6:
1. modify the type of obj for unsigned long according the reviews, and
   modify the same questions in RoCE module
2. fix the spelling error
3. fix the Signed-off-by signatures

Changes v4 -> v5:
1. redesign the patchset for RoCE modules in order to split the huge
   patch into small patches
2. fix the directory path for RoCE module. Delete the hisilicon level.
3. modify the name of roce_v1_hw into roce_hw_v1

Changes v3 -> v4:
1. modify roce.o into hns-roce.o in Makefile and Kconfig file

Changes v2 -> v3:
1. modify the formats of RoCE driver code base v2 by the experts 
   reviewing. also, it used kmalloc_array instead of kmalloc, kcalloc
   instead of kzalloc, when refer to memory allocation for array
2. remove some functions without use and unconnected macros
3. modify the binding document with RoCE DT base v2 which added
   interrupt-names
4. redesign the port_map and si_map in hns_dsaf_roce_reset
5. add HiSilicon RoCE driver maintainers introduction in MAINTAINERS
   document

Changes v1 -> v2:
1. modify the formats of roce driver code by the experts reviewing
2. modify the bindings file with roce dts. add the attribute named 
   interrput-names.
3. modify the way of defining port mode in hns_dsaf_main.c
4. move the Kconfig file into the hns directory and send it with roce
