[PATCH 00/12] Initial support for Nuclei DemoSoC w/ UX600

[Icenowy Zheng]

This patchset adds support for Nuclei DemoSoC (which is an evaluation
platform made with Nuclei CPU cores and mainly peripherals in original
Hummingbird E203 project, running on FPGA) with UX600 CPU cores.

Most patches are for DT bindings, the remaining ones are adding a
Kconfig option and some DTS/DTSI files. The last one is a workaround for
a severe bug in currently released versions of UX600, which is found
in 5.17 kernel, in which Sv48 support is added to Linux.

Two non-technical patches are in this patchset too, for MAINTAINERS
and .mailmap items.

Icenowy Zheng (12):
  dt-bindings: vendor-prefixes: add Nuclei
  RISC-V: add Nuclei SoC Kconfig option
  dt-bindings: riscv: add compatible strings for Nuclei UX600 series
  dt-bindings: timer: add compatible for Nuclei UX600 CLINT-compat timer
  dt-bindings: interrupt-controller: add compatible string for UX600
    PLIC
  dt-bindings: serial: add compatible string for Nuclei DemoSoC UART
  dt-bindings: spi: add compatible string for Nuclei DemoSoC SPI
  dt-bindings: riscv: add binding for Nuclei platform boards
  riscv: dts: add device tree for Nuclei DemoSoC w/ UX600 on DDR200T
  RISC-V: workaround Nuclei UX600 cores with broken SATP CSR
  MAINTAINERS: add myself as Nuclei SoCs/CPUs supporter
  mailmap: add Icenowy Zheng's Nuclei mail addresses
