ifdfake - Create an IFD with just a section layout
This new tool called `ifdfake` just creates an empty Intel Firmware Descriptor (IFD) and writes the IFD signature plus the section layout given on the command line. usage: ifdfake [(-b|-m|-g|-p) <start>:<end>]... <output file> -b | --bios <start>:<end> BIOS region -m | --me <start>:<end> Intel ME region -g | --gbe <start>:<end> Gigabit Ethernet region -p | --platform <start>:<end> Platform Data region -h | --help print this help <start> and <end> bounds are given in Bytes, the <end> bound is inclusive. All regions must be multiples of 4K in size and 4K aligned. The descriptor region always resides in the first 4K. An IFD created with ifdfake won't work as a replacement for a real IFD. Never try to flash such an IFD to your board! The output of ifdfake can be utilized to build an image with just the later added sections (like coreboot itself) being valid. The resulting image can then be partially written to a machines flash ROM to just update coreboot (i.e. the BIOS section).
