试图解决 seewo-sv21 开发板dts设备树cpu频率不正常的问题，为编译方便（我菜），将所有ophub和unifreq都替换为了danteliu119 需fork以下repo unifreq/linux-5.10.y-rk35xx ophub/kernel ophub/amlogic-s9xxx-armbian ophub/firmware 替换所有danteliu119为你的用户名 dts瞎改的 来源参照： rk3568-seewo-rubin rk3568-seewo-new rk3568-seewo-sv21_factory 以及 liwei19920307/armbian coolsnowwolf/lede

修改 linux-5.10.y/arch/arm64/boot/dts/rockchip/rk3568-seewo-sv21.dts amlogic-s9xxx-armbian/build-armbian/armbian-files/common-files/etc/model_database.conf 中的 stable/6.6.y 为 rk35xx/5.10.y 可使用5.10.160内核

编译使用kernel中的compile-release-rk35xx-kernel，编译rk内核5.160 或者amlogic-s9xxx-armbian中的compile-kernel5.yml编译内核，Build armbian5编译armbian，Rebuild armbian5更新内核

比黑豹x2稍微高一点点 符合频率

网卡有一个，其它能力不足不看了。
