In linux kernel since version 2.6.12
If you say Y here, your CLPS711x-based kernel will use the bootstrap
mode memory map instead of the normal memory map.
Processors derived from the Cirrus CLPS711X core support two boot
modes. Normal mode boots from the external memory device at CS0.
Bootstrap mode rearranges parts of the memory map, placing an
internal 128 byte bootstrap ROM at CS0. This option performs the
address map changes required to support booting in this mode.
You almost surely want to say N here.
