trusted_domain load error about quard_star_tutorial HOT 2 CLOSED

Hi @zhutang, I tried using your toolchain. When I enter ./riscv64-unknown-elf-gcc -v to see the result.

Using built-in specs.
COLLECT_GCC=./riscv64-unknown-elf-gcc

-mcmodel=medlow is not an option we need. Because trusted_fw.bin need to link to high addresses above 0x80000000.You can refer to the instructions here for the correct toolchain compilation options(sorry only in chinese).

	2021.07.28(晚上):trusted_domain裸机程序可以使用newlib了，因此修改了一下启动脚本并做了相关newlib桩函数的移植，然后编译发现出错，原来是因为我们使用编译选项-mcmodel=medany来保证程序可以链接到0x80000000以上的高地址，但是默认编译的带newlib的编译器使用了-mcmodel=medlow来编译c库，因此无法链接，又踩到一个坑，只好重新编译了。最终总结编译命令如下:
	```shell
	# 用于裸机带newlib的gcc
	./configure --prefix=/opt/gcc-riscv64-unknown-elf --with-cmodel=medany
	make -j16
	# 用于linux带glibc的gcc
	./configure --prefix=/opt/gcc-riscv64-unknown-linux-gnu
	make linux -j16
	```
	到这里我们的编译器基本更换完成，后面如果遇到问题终于不用担心别人提供的二进制开发工具是否存在问题了，我们拥有全部的源码可以自行编译、debug、fix问题，O(∩_∩)O哈哈~

谢谢！我用你发的这个编译器

成功完成了trusted_domain的编译，但用这个

编译器编译busybox的时候有些问题：

Note: if build needs additional libraries, put them in CONFIG_EXTRA_LDLIBS.
Example: CONFIG_EXTRA_LDLIBS="pthread dl tirpc audit pam"
make: *** [Makefile:718：busybox_unstripped] 错误 1

然后切换到这个

编译器编译busybox和rootfs之后，就成功运行了。
