| tristate "Restricted Access Region Register Driver" |
| depends on PCI |
| default n |
| ---help--- |
| This driver allows other kernel drivers access to the |
| contents of the restricted access region control registers. |
| |
| The restricted access region control registers |
| (rar_registers) are used to pass address and |
| locking information on restricted access regions |
| to other drivers that use restricted access regions. |
| |
| The restricted access regions are regions of memory |
| on the Intel MID Platform that are not accessible to |
| the x86 processor, but are accessible to dedicated |
| processors on board peripheral devices. |
| |
| The purpose of the restricted access regions is to |
| protect sensitive data from compromise by unauthorized |
| programs running on the x86 processor. |
