Device Partitioning
The ICH10 SPI Flash controller supports two sets of attributes in SPI flash space. This
allows for supporting an asymmetric flash component that has two separate sets of
attributes in the upper and lower part of the memory array. An example of this is a
flash part that has different erase granularities in two different parts of the memory
array. This allows for the usage of two separate flash vendors if using two different
flash parts.
