compile error for rpi4

PLATFORM=rpi4 DEMO=linux+freertos Use automated make to comolie, meet error as below log:

I have add -Wno-array-bounds to makefile to bypass this issue, but I am not sure is the right solution.

Could you please indicate what is the toolchain you are using. Also, did you make any changes to the code or changed the bao-hypervisor's repo tag?

I did not change the code, and below is my toolchain.

It seems this was an issue triggered by more recent compiler versions. It is fixed by e221a9c.

我已经将 -Wno-array-bounds 添加到 makefile 以绕过这个问题，但我不确定是否是正确的解决方案。
