[PATCH v2 11/21] ARM: cpu: remove unnecessary CONFIG_SYS_SUPPORTS_64BIT_KERNEL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For ARM, SYS_SUPPORTS_64BIT_KERNEL is selected exclusively by symbols
that also select CPU_SUPPORTS_64BIT_KERNEL, so we can drop
SYS_SUPPORTS_64BIT_KERNEL safely.
