From: Padmarao Begari <padmarao.begari@microchip.com>
This patch set adds Microchip PolarFire SoC Icicle Kit support
to RISC-V U-Boot.
The patches are based upon latest U-Boot tree
(https://gitlab.denx.de/u-boot/u-boot.git) at commit id
9dc6aef8c963ae17e1263b89c692792fce0c7198
All drivers namely: NS16550 Serial, Microchip clock,
Cadence eMMC and Cadence MACB Ethernet work fine on actual
Microchip PolarFire SoC Icicle Kit.
Padmarao Begari (8):
riscv: Add Microchip MPFS Icicle Kit support
riscv: dts: Add device tree for Microchip Icicle Kit
dt-bindings: clock: Add indexes for reset signals
riscv: Add DMA 64-bit address support
net: macb: Add DMA 64-bit address support for macb
net: macb: Add phy address to read it from device tree
clk: Add Microchip PolarFire SoC clock driver

This patch adds Microchip MPFS Icicle Kit support. For now, only
NS16550 Serial, Microchip clock, Cadence eMMC and MACB drivers are
only enabled. The Microchip MPFS Icicle defconfig by default builds
U-Boot for S-Mode because U-Boot on Microchip PolarFire SoC will run
in S-Mode as payload of HSS + OpenSBI.

+Microchip PolarFire SoC Icicle Kit
+==================================
+
+RISC-V PolarFire SoC
+---------------------
+The PolarFire SoC is the 4+1 64-bit RISC-V SoC from Microchip.
+
+The Icicle Kit development platform is based on PolarFire SoC and capable
+of running Linux.
+
+Mainline support
+----------------
+The support for following drivers are already enabled:
+
+1. NS16550 UART Driver.
+2. Microchip Clock Driver.
+3. Cadence MACB ethernet driver for networking support.
+4. Cadence MMC Driver for eMMC/SD support.
+
+Booting from eMMC using HSS
+---------------------------
+
+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 microchip_mpfs_icicle_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 HSS with OpenSBI) is required to
+boot the u-boot.bin in S-mode.
+
+Currently, the u-boot.bin is used as a payload of the HSS firmware.
+
+You will be creating a payload from `u-boot-dtb.bin`.
+Copy this file to the toplevel HSS (Hart Software Services) directory.
+
+Creating the HSS payload
+------------------------
+
+Please refer to HSS documenation to build the HSS firmware.
+(Note: HSS git repo is at
+https://github.com/polarfire-soc/hart-software-services/blob/master
+/tools/hss-payload-generator/README.md)
+
+Once the payload binary is generated, it should be copied to the eMMC.
+
+FPGA design with HSS programming file
+-------------------------------------
+https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/boards
+/mpfs-icicle-kit-es/updating-icicle-kit/updating-icicle-kit-design-and-linux.md
+
+The HSS firmware runs from the PolarFire SoC eNVM on reset.
+
+eMMC
+----
+Program eMMC with payload binary is explained in the PolarFire SoC documentation.
+
+(Note: PolarFire SoC Documentation git repo is at
+https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/boards
+/mpfs-icicle-kit-es/updating-icicle-kit/updating-icicle-kit-design-and-linux.md#eMMC
+
+Once the payload image is copied to the eMMC, press CTRL+C in the HSS command
+line interface, then type 'boot' and enter to boot the newly copied image.
+
+.. code-block:: none
+
+ sudo dd if=<payload_binary> of=/dev/sdX bs=512
+
+Booting
+-------
+you should see the U-Boot prompt on UART1.

The way patches are organized, it breaks git bisect-ability
because PATCH2 depends on PATCH3. Also, PATCH3 should
be squashed into PATCH7.
Based on dependency, here's better ordering of patches:
PATCH1) riscv: Add DMA 64-bit address support
PATCH2) net: macb: Add DMA 64-bit address support for macb
PATCH3) net: macb: Add phy address to read it from device tree
PATCH4) clk: Add Microchip PolarFire SoC clock driver
(Note: PATCH4 also include "dt-bindings: clock: Add indexes for reset signals")
PATCH5) riscv: dts: Add device tree for Microchip Icicle Kit
PATCH6) riscv: Add Microchip MPFS Icicle Kit support
PATCH7) doc: board: Add Microchip MPFS Icicle Kit doc

Anup

I see that HSS uses uart0 and over here we are assigning uart1. This
forces users to always use two UARTs on the ICICLE board. This is very
inconvenient and not at all consistent with SiFive Unleashed and other
ARM boards.
It should be user's choice to use whether or not to use separate uart for
S-mode software. Please don't force multiple uarts by default.
By default, I suggest to use uart0 for U-Boot S-mode. If users want to
use separate uart for Linux then they can do it using "bootargs" passed
to Linux kernel from U-Boot.
U-Boot being transient in the boot flow should use same uart as
previous booting stage (in this case HSS).

Like I mentioned in another PATCH, all the HSS boot logs are on
UART0 and U-Boot appears on UART1. This is very inconvenient.
Please use UART0 for U-Boot and users can easily use UART1
for Linux (if they want) using bootargs passed to Linux kernel.
This will be consistent with other boards as well.
Regards,
Anup
