[PATCH v5 0/8] add Voyager board support

[Ben Zong-You Xie]

The Voyager is a 9.6” x 9.6” Micro ATX form factor development board
including Andes QiLai SoC. This patch series adds minimal device tree
files for the QiLai SoC and the Voyager board [1].

Now only support basic uart drivers to boot up into a basic console. Other
features will be added later.

Changelog from v4 to v5:
  - Rebase the series on torvalds/master
  - Clarify the patch dependencies (2 <- 4 <- 5 <- 6) in the patch description

v4: https://lore.kernel.org/all/20250514095350.3765716-1-ben717@andestech.com/

Changelog from v3 to v4:
  - Restore the modification to cache-sets and cache-size in patch 6
  - Do not constrain renesas,r9a07g043f-ax45mp-cache since it's independent to
    this series.
  - Delete the redundant example added by patch 6

v3: https://lore.kernel.org/all/20250513094933.1631493-1-ben717@andestech.com/

Changelog from v2 to v3:
  - Rebase the series on Conor/riscv-soc-for-next
  - Reform patch 6 as suggested by Conor
  - Modify l2_cache's compatible in qilai.dtsi due to patch 6
  - Add Conor's Acked-by tag to patch 4

Changelog from v1 to v2:
  - Add detailed descriptions to PLIC_SW and PLMT0
  - Move the aliases node and memory node from qilai.dtsi to qilai-voyager.dts
  - Drop "status = okay" in each CPU node since the status property is by
    default "okay"
  - Reorder the nodes in qilai.dtsi by unit address in ascending order
  - Add myself as the maintainer of Andes's SoC tree
  - Add Rob's Reviewed-by tag to patch 2
