需求：使用intel的8265替换板载的wifi模块，下面是我的操作步骤
先在rk3588上安装

sudo apt-get install firmware-iwlwifi

发现并没有出现wifi图标，于是看到sdk，打开i对应的wifi驱动配置，如下

CONFIG_CFG80211=y
CONFIG_MAC80211=y
CONFIG_WANT_DEV_COREDUMP=y
CONFIG_HAS_IOMEM=y
CONFIG_IWLWIFI=y
CONFIG_IWLDVM=y
CONFIG_IWLMVM=y
CONFIG_EVENT_TRACING=y
CONFIG_ACPI=y
CONFIG_MAC80211_DEBUGFS=y
CONFIG_IWLWIFI_DEBUGFS=y
CONFIG_IWLWIFI_DEVICE_TRACING=y

//查看dmesg发现如下

发现找不到iwlwifi-8265-22.ucode iwlwifi-8265-36.ucode我查找一下是已经安装了的

➜  ~ ls /lib/firmware/iwlwifi-82*
/lib/firmware/iwlwifi-8265-22.ucode  /lib/firmware/iwlwifi-8265-36.ucode

我已经安装了对应的iwlwifi-8265-22.ucode iwlwifi-8265-36.ucode，但是提示找不到，我该如何配置iwlwifi

换个rootfs吧，换了firefly的rootfs 能找到ucode了

目前发现toybrick的rootfs挺多bug，不知道是不是适配了gnome的原因
