t3 uboot 流程分析
看 t3 的芯片手册,可以看到t3 的启动流程：板卡上有个 36KB的 ROM boot loader，然后进入fast boot， fast boot 启动后加载存储设备中的 BOOT0，启动boot0 ,boot0再引导uboot 启动；

t3 uboot 编译时需要输入 ：make sun8iw11p1_config
通过顶层 Makefile 分析，在执行make sun8iw11p1_config时，调用了：
%_config:: outputmakefile
@$(MKCONFIG) -A $(@:_config=) // mkconfig -A sun8iw11p1
mkconfig:
if [ \( $# -eq 2 \) -a \( "$1" = "-A" \) ] ; then
# Automatic mode
line=`awk '($0 !~ /^#/ && $7 ~ /^'"$2"'$/) { print $1, $2, $3, $4, $5, $6, $7, $8 }' $srctree/boards.cfg`
if [ -z "$line" ] ; then
echo "make: *** No rule to make target \`$2_config'. Stop." >&2
exit 1
fi
set ${line}
# add default board name if needed
[ $# = 3 ] && set ${line} ${1}
fi
将从 boards.cfg 中读取CPU相关配置信息
最终在 u-boot-2014.07/include 目录下生成 config.h文件
建立在 u-boot-2014.07/arch/arm/include/asm 的 arch 链接
lrwxrwxrwx 1 root root 15 Apr 2 16:51 arch -> arch-sun8iw11p1
综上，总结下mkconfig文件（或者叫mkconfig -A sun8iw11p1）的作用：
l 确定ARCH、CPU、BOARD等变量的值，并存到./include/config.mk文件中
l 建立板级相关的 ./include/config.h文件
l 建立指向其他文件的软链接
include/config.mk 中的内容
ARCH = arm
CPU = armv7
BOARD = sun8iw11p1
VENDOR = sunxi
SOC = sun8iw11p1
LDSCRIPT 的路径 即为u-boot-2014.07/arch/arm/cpu/u-boot.lds
CPUDIR=arch/$(ARCH)/cpu$(if $(CPU),/$(CPU),) == u-boot-2014.07/arch/arm/cpu/armv7
