based on the work of Matthias 'mazzoo' Wenzel this patch adds... - pretty printing of those ICH/PCH flash descriptors that are cached/mapped by the chipset (and which are therefore reachable via FDOC/FDOD registers) and - a new tool to the util directory that is able to decode all flash descriptors stored in a flash dump file.
