[PATCH v8 18/21] ARM64 / ACPI: Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64

From: Hanjun Guo
Date: Mon Feb 02 2015 - 07:49:56 EST


From: Al Stone <al.stone@xxxxxxxxxx>

ACPI reduced hardware mode is disabled by default, but ARM64
can only run properly in ACPI hardware reduced mode, so select
ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64.
