Description

TypeExtField

Type extension field, allows you to configure memory access type, for example strongly ordered, peripheral.

IsShareable

Region is shareable between multiple bus masters.

IsCacheable

Region is cacheable, i.e. its value may be kept in cache.

IsBufferable

Region is bufferable, i.e. using write-back caching. Cacheable but non-bufferable regions use write-through policy.
