2012-11-09Fix Segmentation Fault in ifdtoolStefan Reinauer
If a section is bigger than the FD file it is injected into, and the FD lies about the size of the FD file, ifdtool would crash because reading in the section writes beyound the FD file in memory.

2012-05-24Add EM100 mode to Intel Firmware Descriptor toolStefan Reinauer
To avoid having two copies for every firmware descriptor (one for EM100 use and one for real SPI flash use), add an EM100 mode to ifdtool that allows to "dumb down" a fast image to the settings required for the EM100 to work.

2012-03-30Allow components smaller than declared size.Vadim Bendebury
idftool was failing to add the ME blobs into the output image in case the blob size does not exactly match the size allocated for it in the flashrom structure. It is difficult to set the field in the structure to exactly match the size (for some reason Intel flash tool fails to insert the correct size even when given the exact ME blob). On the other hand there is no harm in using am ME blob smaller than the allocated size, this change modifies the tool building the image to allow for smaller components.
