x86: Correct Minnowboard instructions to use the right descriptor

Browse source 
The descriptor provided with the FSP does not seem to work. Update the
instructions to use the descriptor from the original Intel firmware.

Obtain the VGA RAM (Vga.dat at the time of writing) and put it into the same
directory: board/intel/minnowmax/vga.bin
You still need two more binary blobs. These come from the sample SPI image
provided in the FSP (SPI.bin at the time of writing).
You still need two more binary blobs. The first comes from the original
firmware image available from:
http://firmware.intel.com/sites/default/files/2014-WW42.4-MinnowBoardMax.73-64-bit.bin_Release.zip
Unzip it:
$ unzip 2014-WW42.4-MinnowBoardMax.73-64-bit.bin_Release.zip
Use ifdtool in the U-Boot tools directory to extract the images from that
file, for example:
$ ./tools/ifdtool -x MNW2MAX1.X64.0073.R02.1409160934.bin
This will provide the descriptor file - copy this into the correct place:
$ cp flashregion_0_flashdescriptor.bin board/intel/minnowmax/descriptor.bin
Then do the same with the sample SPI image provided in the FSP (SPI.bin at
the time of writing) to obtain the last image. Note that this will also
produce a flash descriptor file, but it does not seem to work, probably
because it is not designed for the Minnowmax. That is why you need to get
the flash descriptor from the original firmware as above.
$ ./tools/ifdtool -x BayleyBay/SPI.bin
$ cp flashregion_2_intel_me.bin board/intel/minnowmax/me.bin
$ cp flashregion_0_flashdescriptor.bin board/intel/minnowmax/descriptor.bin
Now you can build U-Boot and obtain u-boot.rom
