[coreboot] DFI Infinity NF570-M2/G motherboard

[Tiago Marques]

1MB = 1 million bytes
1Mb = 1Mbit = 1 million bits
1MiB (mebibyte)  = 1.048.576 bytes, which is what most people call mega
byte(MB), but isn't.
1Mibit = 1 Mib = 1.048.576 bits

Usually when a chip is said to have 1MB it really has 1MiB, not less, and
8Mib, not 8Mb.
