CONFIG_64BIT

(No prompt – not directly user assignable.)

Type: bool

Help

This option tells the build system that the target system is
using a 64-bit address space, meaning that pointer and long types
are 64 bits wide. This option is selected by arch/$ARCH/Kconfig,
soc/**/Kconfig, or boards/**/Kconfig and the user should generally
avoid modifying it.

Defaults

No defaults. Implicitly defaults to n.
