| = BBAR on ICH8 = |
| There is no sign of BBAR (BIOS Base Address Configuration Register) in the |
| public datasheet (or specification update) of the ICH8. Also, the offset of |
| that register has changed between ICH7 (SPIBAR + 50h) and ICH9 (SPIBAR + |
| A0h), so we have no clue if or where it is on ICH8. Out current policy is to |
| not touch it at all and assume/hope it is 0. |

| = Accesses beyond region bounds in descriptor mode = |
| Intel's flash image tool will always expand the last region so that it covers |
| the whole flash chip, but some boards ship with a different configuration. |
| It seems that in descriptor mode all addresses outside the used regions can not |
| be accessed whatsoever. This is not specified anywhere publicly as far as we |
| could tell. flashrom does not handle this explicitly yet. It will just fail |
| when trying to touch an address outside of any region. |
