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