补丁

1. 制作补丁

diff -urN u-boot-2010.06/ u-boot/ > ../u-boot-just-work.patch

u-boot-2010.06/ 是原始的文件夹

u-boot/是我添加了很多修改后的文件夹

../u-boot-just-work.patch是补丁

2. 打补丁

To revert a previously applied patch, use the -R argument to patch.
So, if you applied a patch like this:

cd xxxxx/
patch -p1 < ../patch-x.y.z


You can revert (undo) it like this:

cd xxxxx/
patch -R -p1 < ../patch-x.y.z

示例

cd /development/mini2440/u-boot-2010.06/

[root@localhost u-boot-2010.06]# patch -p1 < /home/harvis/Desktop/u-boot-just-work.patch
