This patch set is to add SiFive fu740 chip and HiFive Unmatched board
support. Patches are split into several parts:
- [PATCH v9 1/8] support for fu740 cpu
- [PATCH v9 2/8] support for fu740 clk driver
- [PATCH v9 3/8] rename and support for fu740 ram driver
- [PATCH v9 4/8] add pcie driver
- [PATCH v9 5/8] dts for SiFive fu740
- [PATCH v9 6/8] dts for SiFive Unmatched board
- [PATCH v9 7/8] add Unmatched board support
- [PATCH v9 8/8] clear feature disable CSR
Description
- For fu740 cpu support, reuse most of fu540 cpu.
- For prci driver, add one abstract layer to separate fu540 and
fu740. Move orignal fu540 code to separate files.
- For pcie driver, it depends on gpio, prci, clk and reset drivers
to do init&reset works. Also based on pcie_dw_common.c
- Align with Linux DT file.
Tests and patch checks
- Able to boot both unmatched and unleashed boards.
- PCIe tests
. M.2 NVMe SSD
. e1000 compatibale ethernet adapter (ping&tftpboot)
. pci-to-usb adapter(usb mass storage)
- checkpatch is performed. To keep code derived from other boards
the same, ignore some warnings/errors in [PATCH 7/8].

. Remove ECAM compatible string to align with Linux pcie driver
and add Reviewed-by to [PATCH v8 4/7]
. Drop last patch [PATCH v7 8/8] for drivers/net/macb.c and use
the same compatible string, 'sifive,fu540-c000-gem', to align with
Linux driver.
- V7
. Rebase to latest master branch
. Moved dts for fu740 patch [v6 1/7] to [v7 5/8] and seperate dts of
Unmatched board from [v6 6/7] into [v7 6/8]
. Applied PCIe refactoring patch to base on the common code in
pcie_dw_common.c
- V6
. Remove redundant DT string for 1.2GHz CPU clock and squash to
[1/7]
- V5
. Fix unleashed build error in patch [6/8]
. Append one more set for 1.2GHz CPU speed
. Add "#include <asm/global_data.h>" back to sifive_ddr.c
. Add Reviewed-by to [4/8] and [7/8]
- V4
. fixed incorrect file name in ./board/sifive/unmatched/Makefile
. fixed link in doc/board/sifive/index.rst, passed 'make htmldocs'
- V3
. Rebase to unleashed rename v2 patch
. Rename
doc/board/sifive/unmatched.rst
board/sifive/unmatched/unmatched.c
. Fix tail whitespace
. Add 'git mv' info to ram driver and merge patch back to one

. Add reviewed-by to patch [6/7]
. Add 'gpio-poweroff' node for upcoming opensbi integration
- V2
. Rebase to unleashed rename patch
. remove unnessaary fu540 changes
. split ram driver patch into 2 to keep 'git mv' info
. use a shorter name for unmatched support
. Remove redundant&incorrect temperature-sensor in DT
. Remove unnecessary USB EHCI & OHCI from defconfig
. Revised fu740 doc
. Fixed year of copyright
. Add reviewed-by received in v1 patch
