The change is not board-specific: every MT7981 board with eMMC or SD currently runs its bus at half the rate its device tree requests and will get the requested rate with this patch, matching MediaTek's SDK kernel and U-Boot. I do not have a GL-XE3000, CMCC RAX3000M or Cudy TR3000 to confirm on; the test scripts are in https://github.com/openwrt/openwrt/issues/25960 for anyone who does.
