This patch set is to add SiFive fu740 chip and HiFive Unmatched board support. Patches are split into several parts:
- [PATCH v12 1/8] support for fu740 cpu - [PATCH v12 2/8] support for fu740 clk driver - [PATCH v12 3/8] rename and support for fu740 ram driver - [PATCH v12 4/8] add pcie driver - [PATCH v12 5/8] dts for SiFive fu740 - [PATCH v12 6/8] dts for SiFive Unmatched board - [PATCH v12 7/8] add Unmatched board support - [PATCH v12 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.

Remove unused CLK_SIFIVE_FU540_PRCI from Kconfig [PATCH v8 2/8] and remove CONFIG_CLK_SIFIVE_PRCI=y from unleashed config in [PATCH v8 7/7] . 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 .
