执行buildman --fetch-arch arm提示\"urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>\"如何处理？

答: 在uboot源码的tools/buildman/toolchain.py中取消证书验证，修改内容如下:

diff --git a/tools/buildman/toolchain.py b/tools/buildman/toolchain.py
index a65737fdf8..94877f1047 100644
