otherwise, the default values are assigned. |

If processor has no CP15 register, this processor ID is |

used instead of the auto-probing which utilizes the register. |

config REMAP_VECTORS_TO_RAM |
|
bool 'Install vectors to the beginning of RAM' |
|
help |
|
The kernel needs to change the hardware exception vectors. |
|
In nommu mode, the hardware exception vectors are normally |
|
placed at address 0x00000000. However, this region may be |
|
occupied by read-only memory depending on H/W design. |
|
|
|
If the region contains read-write memory, say 'n' here. |
|
|
|
If your CPU provides a remap facility which allows the exception |
|
vectors to be mapped to writable memory, say 'n' here. |
|
|
|
Otherwise, say 'y' here. In this case, the kernel will require |
|
external support to redirect the hardware exception vectors to |
|
the writable versions located at DRAM_BASE. |

config ARM_MPU |

bool 'Use the ARM v7 PMSA Compliant MPU' |

depends on CPU_V7 || CPU_V7M |
|
default y if CPU_V7 |
|
help |
|
Some ARM systems without an MMU have instead a Memory Protection |
|
Unit (MPU) that defines the type and permissions for regions of |
|
memory. |
|
|
|
If your CPU has an MPU then you should choose 'y' here unless you |
|
know that you do not want to use the MPU.
