xr806代码量太大导致编译失败的解决方法

[cx1253176313]

我使用的系统是OpenHarmony-v1.1.2-LTS，device和vendor仓是最近更新的（2022/1/14）。
我移植好最新的固件之后，发现只有hollowword例程可以编译成功，其余的稍微大一点的代码都编译报错（例如wlan_demo）：

发现错误提示里面全是一些关于代码段长度的信息。后来经过调试后发现，只要将控制台移除编译，就可以节省很多代码空间，从而成功通过编译。

只需要将device\xradio\xr806\BUILD.gn文件中44行的"adapter/console:app_console"注释掉就可以将控制台移除编译。

if (IsBootloader == "false") {
    deps += [
      "adapter/hals:adapter",
      #"adapter/console:app_console",
      "ohosdemo:ohosdemo"
    ]
  }

这个错误还可以修改分区信息通过编译，详情：https://bbs.aw-ol.com/topic/775
