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].

From: Green Wan @ 2021-03-11 13:49 UTC (permalink / raw)
To: u-boot
Add pcie driver for SiFive fu740, the driver depends on
fu740 gpio, clk and reset driver to do init. Force running at Gen1
for better capatible enumeration.
Several devices are tested:
a) M.2 NVMe SSD
b) USB-to-PCI adapter
c) Ethernet adapter (E1000 compatible)

+HiFive Unmatched
+================
+
+FU740-C000 RISC-V SoC
+---------------------
+The FU740-C000 is a 4+1 64-bit RISC-V core SoC from SiFive.
+
+The HiFive Unmatched development platform is based on FU740-C000 and capable
+of running Linux.
+
+Mainline support
+----------------
+The support for following drivers are already enabled:
+
+1. SiFive UART Driver.
+2. SiFive PRCI Driver for clock.
+3. Cadence MACB ethernet driver for networking support.
+4. SiFive SPI Driver.
+5. MMC SPI Driver for MMC/SD support.
+
+Booting from MMC using u-boot-spl
+---------------------------
+
+Building
+--------
+
+1. Add the RISC-V toolchain to your PATH.
+2. Setup ARCH & cross compilation environment variable:
+
+.. code-block:: none
+
+ export CROSS_COMPILE=<riscv64 toolchain prefix>
+
+3. make sifive_hifive_unmatched_fu740_defconfig
+4. make
+
+Flashing
+--------
+
+The current U-Boot port is supported in S-mode only and loaded from DRAM.
+
+A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
+boot the u-boot.bin in S-mode and provide M-mode runtime services.
+
+Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
+firmware. We need to compile OpenSBI with below command:
+
+.. code-block:: none
+
+ make PLATFORM=generic FW_PAYLOAD_PATH=<path to u-boot-dtb.bin>
+
+More detailed description of steps required to build FW_PAYLOAD firmware
+is beyond the scope of this document. Please refer OpenSBI documenation.
+(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
+
+Once the prior stage firmware/bootloader binary is generated, it should be
+copied to the first partition of the sdcard.

+.. code-block:: none

+
+Booting from MMC using U-Boot SPL
+---------------------------------
+
+Building
+--------
+
+Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be
+cloned and built for FU740 as below:
+
+.. code-block:: console
+
+ git clone https://github.com/riscv/opensbi.git
+ cd opensbi
+ make PLATFORM=generic
+ export OPENSBI=<path to opensbi/build/platform/generic/firmware/fw_dynamic.bin>
+
+Now build the U-Boot SPL and U-Boot proper
+
+.. code-block:: console
+
+ cd <U-Boot-dir>
+ make sifive_hifive_unmatched_fu740_defconfig
+ make
+
+This will generate spl/u-boot-spl.bin and FIT image (u-boot.itb)
+
+
+Flashing
+--------
+
+ZSBL loads the U-Boot SPL (u-boot-spl.bin) from a partition with GUID type
+5B193300-FC78-40CD-8002-E86C45580B47
+
+U-Boot SPL expects a U-Boot FIT image (u-boot.itb) from a partition with GUID
+type 2E54B353-1271-4842-806F-E436D6AF6985
+
+FIT image (u-boot.itb) is a combination of fw_dynamic.bin, u-boot-nodtb.bin and
+device tree blob (hifive-unmatched-a00.dtb)
+
+Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)
+
+.. code-block:: none
+
+ # sudo sgdisk --clear \
+ > --set-alignment=2 \
+ > --new=1:34:2081 --change-name=1:loader1 --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \
+ > --new=2:2082:10273 --change-name=2:loader2 --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \
+ > --new=3:10274: --change-name=3:rootfs --typecode=3:0FC63DAF-8483-4772-8E79-3D69D8477DE4 \
+ > /dev/sda
+
+Program the SD card
+
+.. code-block:: none
+
+ sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=34
+ sudo dd if=u-boot.itb of=/dev/sda seek=2082
+
+Booting
+-------
+Once you plugin the sdcard and power up, you should see the U-Boot prompt.

The driver currently depends on fu740 drivers such as prci, clk, gpio and

driver. What do we think of it?

Is it possible to update the existing dw pcie driver to support fu740?
Depending on prci, clk and reset is not a problem. We can use dm_ APIs
to hide device specific (prci, sifive-gpio) stuff.
Unless SiFive made significant changes to the designware PCIe IP, we
should not create a new driver for it.

It's simply due to the limitation in the PLL cannot generate 125 000 000 Hz
clock precisely. The closet one is 125 125 000 HZ.

So FU540 can but FU740 cannot? I would consider this as a hardware
regression ...

Hi Bin,
So far, we'd like to maintain a sifive driver to handle the different
sequences and changes. For example, we don't have a memory region start for
phy registers but other platforms might have. Those differences and details
might need info from other maintainers.
But I do agree with you that we should have certain level common code cross
designware based drivers. Actually, I did give a try on merging them. But I
lack the detail in the first attempt. Every driver looks has its own
specialty. I wasn't 100% sure what the common we should have at the time.
Maybe we can create a "pcie_dw_common.c" or "pcie_designware.c" for all DWC
IP and try to move common functions into it as a start. We can migrate some
dw_pcie_xxx() and data structure from Linux. Then, I can do it on top of
this patch as a RFC so it doesn't break current implementation. What do you
think of it?

Note that 125.125MHz is out of spec, but that's the closest we can get
and 1Gbps works fine based on the tests I did.
This is hardware quirk, and probably a comment explaining this should
be provided here.

Let me remove the change for fu540 first and check on fu540.

I'd like to rename "board/sifive/hifive_unmatched_fu740" to the shorter
name "board/sifive/unmatched". And
"configs/sifive_hifive_unmatched_fu740_defconfig" to
"configs/sifive_unmatched_defconfig" in v2 patch.

Agree. I sent a patch to rename fu540 to unleashed, so that this is consistent.
http://patchwork.ozlabs.org/project/uboot/patch/20210316030622.40768-1-bmeng.cn at gmail.com/
You may rebase v2 on top of that patch.
