One s5p4418 support SD/TF card offline burning

To support this feature, two tools Sd_fdisk and U-boot-head-tool are required.

The Sd_fdisk function is to partition the TF card, U-boot-head-tool is to modify the compilation generated u-boot to fit the s5p4418 hardware boot requirements.

The download address for the two tools is http://download.csdn.net/detail/u010406724/8362055,

Also requires a script to use the two tools sd_fusing.sh, the specific code is as follows:

In addition, of course, U-boot.bin and 2ndboot Two files are required, and these two files will also be available in the official system files.

Before executing the script, you need to make sure that the file looks like this:

Also pay attention to a variable in the script

Disk_tf_enable=0

It is only set to 1 when using a new card or a card that does not burn 4418 programs, and the other is set to 0, lest the format of the TF card be bad.
