- = 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.

- = Unlocking the ME region =
- TODO
