SplitFspBin.py is a python script to support some operations on Intel FSP 2.0 image.

It supports:

• Split Intel FSP 2.0 image into individual FSP-T/M/S/O component

• Rebase Intel FSP 2.0 components to different base addresses

• Generate Intel FSP 2.0 C header file

• Display Intel FSP 2.0 information header for each FSP component

Split Intel FSP 2.0 image

To split individual FSP component in Intel FSP 2.0 image, the following command can be used:

python SplitFspBin.py split [-h] -f FSPBINARY [-o OUTPUTDIR] [-n NAMETEMPLATE]

For example:

python SplitFspBin.py split -f FSP.bin

It will create FSP_T.bin, FSP_M.bin and FSP_S.bin in current directory.

Rebase Intel FSP 2.0 components

To rebase one or multiple FSP components in Intel FSP 2.0 image, the following command can be used:

python SplitFspBin.py rebase [-h] -f FSPBINARY -c {t,m,s,o} [{t,m,s,o} ...] -b FSPBASE [FSPBASE ...] [-o OUTPUTDIR] [-n OUTPUTFILE]

For example:

python SplitFspBin.py rebase -f FSP.bin –c t –b 0xFFF00000 –n FSP_new.bin

It will rebase FSP-T component inside FSP.bin to new base 0xFFF00000 and save the rebased Intel FSP 2.0 image into file FSP_new.bin.

python SplitFspBin.py rebase -f FSP.bin –c t m –b 0xFFF00000 0xFEF80000 –n FSP_new.bin

It will rebase FSP-T and FSP-M components inside FSP.bin to new base 0xFFF00000 and 0xFEF80000 respectively, and save the rebased Intel FSP 2.0 image into file FSP_new.bin file.

Generate Intel FSP 2.0 C header file

To generate Intel FSP 2.0 C header file, the following command can be used:

Python SplitFspBin.py genhdr [-h] -f FSPBINARY [-o OUTPUTDIR] [-n HFILENAME]

For example:

python SplitFspBin.py genhdr -f FSP.bin –n FSP.h

It will create the C header file FSP.h containing the image ID, revision, offset and size for each individual FSP component.

Display Intel FSP 2.0 information header

To display Intel FSP 2.0 information headers, the following command can be used:

Python SplitFspBin.py info [-h] -f FSPBINARY

For example:

python SplitFspBin.py info -f FSP.bin

It will print out the FSP information header for each FSP component.
