tools/intel_vbt_decode: Decode block 4 (Mode Support List)
Decode VBT block 4 (Mode Support List). The contents are just
some kind of list of "Intel mode numbers" (whateer those are).
Example output:
BDB block 4 (28 bytes, min 2 bytes) - Mode support list:
0000: 04 1c 00 30 32 34 36 38 3a 3c 40 42 44 46 48 4a
0010: 4c 50 52 54 56 58 5a 5c 80 81 82 83 84 1a 00
Intel mode numbers:
0x30
...
0x84
Mode list length: 26
