bus system, i.e. the way the CPU talks to the other stuff inside

- bool "Use 64-bit ELF format for building"
- depends on 64BIT
- help
- A 64-bit kernel is usually built using the 64-bit ELF binary object
- format as it's one that allows arbitrary 64-bit constructs. For
- kernels that are loaded within the KSEG compatibility segments the
- 32-bit ELF format can optionally be used resulting in a somewhat
- smaller binary, but this option is not explicitly supported by the
- toolchain and since binutils 2.14 it does not even work at all.
-
- Say Y to use the 64-bit format or N to use the 32-bit one.
-
- If unsure say Y.
