Problem:
failure occurred when calling autopatch.sh in the kernel directory
Solution:
1. Before applying the patch, confirm that the directory is a Git repository
2. The kernel path and kernel version can be obtained through calculation,
so there is no need to add additional parameters
3. Optimize the maximum number of patches to improve performance
4. Optimize lunch patch
5. Optimize debug logs
6. Refactor into functions

Problem:
TEXTOFFSET was changed from 0x00208000 to 0x02008000, causing some
devices to fail to start.
1. t5d Android U upgrade project, ko becomes build, uImage size
increases to 36MB. It is too big to relocate.
2. There is only 48MB in 0x020080000~0x5000000 area, and cannot
open kasan.
Solution:
1. use new config CONFIG_AMLOGIC_RAMDUMP_TEXTOFFSET instead of
CONFIG_AMLOGIC_RAMDUMP. And TEXTOFFSET is 0x00208000 default.
2. Use a new solution instead of modifying TEXT. Specifically,
during kernel panic, move 0-24MB to a higher address. Reboot to
uboot and then copy back.
