| bool "Set flash/sdram size and base addr" |
| help |
| Say Y to manually set the base addresses and sizes. |
| otherwise, the default values are assigned. |

| config DRAM_BASE |
| hex '(S)DRAM Base Address' if SET_MEM_PARAM |
| default 0x00800000 |

| config DRAM_SIZE |
| hex '(S)DRAM SIZE' if SET_MEM_PARAM |

| depends on !(CPU_CP15 || CPU_V7M) |
| help |
| 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 |
| 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. |
