Add support for ESWIN EIC7700 SoC consisting of SiFive Quad-Core
P550 CPU cluster and the first development board that uses it, the
SiFive HiFive Premier P550.

This patch series adds initial device tree and also adds ESWIN
architecture support.

Boot-tested using intiramfs with Linux 6.14.0-rc2 on HiFive Premier
P550 board using U-Boot 2024.01 and OpenSBI 1.4.

Darshan Prajapati (3):
  dt-bindings: riscv: Add SiFive P550 CPU compatible
  dt-bindings: interrupt-controller: Add ESWIN EIC7700 PLIC
  dt-bindings: timer: Add ESWIN EIC7700 CLINT

Min Lin (2):
  riscv: dts: add initial support for EIC7700 SoC
  riscv: dts: eswin: add HiFive Premier P550 board device tree

Pinkesh Vaghela (2):
  riscv: Add Kconfig option for ESWIN platforms
  cache: sifive_ccache: Add ESWIN EIC7700 support

Pritesh Patel (3):
  dt-bindings: vendor-prefixes: add eswin
  dt-bindings: riscv: Add SiFive HiFive Premier P550 board
  dt-bindings: cache: sifive,ccache0: Add ESWIN EIC7700 SoC
    compatibility

There's no git tree in your MAINTAINERS entry, nor mention here of what
the story is going to be in terms of sending patches to Arnd. Who is
going to be doing that?

Cheers,
