Hi Paul,

Add support for building flattened DT files from DT source files under
arch/riscv/boot/dts. Follow existing kernel precedent from other SoC
architectures. Start our board support by adding initial support for
the SiFive FU540 SoC and the first development board that uses it, the
SiFive HiFive Unleashed A00.

This third version of the patch set adds I2C data for the chip,
incorporates all remaining changes that riscv-pk was making
automatically, and addresses a comment from Rob Herring

Boot-tested on v5.2-rc1 on a HiFive Unleashed A00 board, using the
BBL and open-source FSBL, with modifications to pass in the DTB
file generated by these patches.

Tested this series on top of v5.2-rc3 on HiFive Unleashed board using
OpenSBI + mainline u-boot (master branch as of today).

This patch series can be found, along with the PRCI patch set
and the DT macro prerequisite patch, at:

nit: I only see this series in that branch, not any of the prerequisite
patches you mentioned, which made me assume I could this series alone on
top of v5.2-rc3, which worked just fine.

I tried only this series on top of v5.2-rc3. Kernel boots file with DT updated via U-Boot. But networking didn't come up.

Do you have networking up after the boot? If yes, can you please share the config.
