Subject: [PATCH v4 2/5] drivers: acpi: add dependency of EFI for arm64
Date: Mon, 23 Jul 2018 10:57:29 +0900	[thread overview]
Message-ID: <20180723015732.24252-3-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <20180723015732.24252-1-takahiro.akashi@linaro.org>

As Ard suggested, CONFIG_ACPI && !CONFIG_EFI doesn't make sense on arm64,
while CONFIG_ACPI and CONFIG_CPU_BIG_ENDIAN doesn't make sense either.

As CONFIG_EFI already has a dependency of !CONFIG_CPU_BIG_ENDIAN, it is
good enough to add a dependency of CONFIG_EFI to avoid any useless
combination of configuration.

This bug, reported by Will, will be revealed when my patch series,
"arm64: kexec,kdump: fix boot failures on acpi-only system," is applied
and the kernel is built under allmodconfig.
