otherwise, the default values are assigned.

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.

default y

|
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.
