查看bootm.c:代码，发现里面明明存在get_sp（）函数，支持在一些宏定义条件下。可能是这些宏未定义导致该函数未编译。查到网上一个patch：

[PATCH] arm: get_sp() should always be compiled

From: Po-Yu Chuang faraday-tech.com>

get_sp() was incorrectly excluded if none of

CONFIG_SETUP_MEMORY_TAGS

CONFIG_CMDLINE_TAG

CONFIG_INITRD_TAG

CONFIG_SERIAL_TAG

CONFIG_REVISION_TAG

were defined.

修改完毕后，再次编译通过（从编译过程来看，新版本的BUG还不少）。
