2014-02-28util/ifdtool: cleanup some magic numbersChris Douglass
There are five firmware regions that are (currently) defined. This was assumed throughout the ifdtool code with many literal 4s and 5s. This patch changes them to refer to a new #define NUM_REGIONS.

2014-02-28util/ifdtool: add option to change flash layoutChris Douglass
The new option "--newlayout <file>" will read <file> in flashrom's layout format and copy flash regions from the current flash image file to a new flash image file. If a region grows, the padding is added at the beginning of the target region in the new file so that the data is "right-aligned" to the end of the region. If a region shrinks, a warning is given and the tail end of existing data is copied to the target region in the new file. Regions of zero or negative size are ignored. (In the example below 00fff000:00000fff regions are an artifact of the address encoding in the register fields.) Example Usage: Given a flash image for a board with a Sandy Bridge processor and Intel 6-Series chipset in the file vpx7654.bin ifdtool --layout layout.txt vpx7564.bin will yield the file layout.txt: 00000000:00000fff fd 00180000:003fffff bios 00001000:0017ffff me 00fff000:00000fff gbe 00fff000:00000fff pd Notice that the "bios" portion extends to the end of the 4MB flash. It may be edited to extend the bios portion to consume to the extent of an 8MB flash. like layout2.txt: 00000000:00000fff fd 00180000:007fffff bios 00001000:0017ffff me 00fff000:00000fff gbe 00fff000:00000fff pd ifdtool --newlayout layout.txt vpx7654.bin will create a file vpx7654.bin.new that is 8MB.

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.
