Subject: [Buildroot] [PATCH 2/5] arch/Config.in: remove BR2_ARCH_HAS_MMU_MANDATORY from BR2_aarch64*
Date: Tue, 19 Apr 2022 23:34:46 +0200	[thread overview]
Message-ID: <20220419213450.887728-2-thomas.petazzoni@bootlin.com> (raw)
In-Reply-To: <20220419213450.887728-1-thomas.petazzoni@bootlin.com>

Selecting BR2_ARCH_HAS_MMU_MANDATORY from BR2_aarch64 and
BR2_aarch64_be doesn't make much sense, because the actual ARM cores
described in arch/Config.in.arm then all select
BR2_ARCH_HAS_MMU_OPTIONAL. So we end up with both
BR2_ARCH_HAS_MMU_OPTIONAL and BR2_ARCH_HAS_MMU_MANDATORY, which
doesn't make any sense.

To prevent this, we remove the selection of BR2_ARCH_HAS_MMU_MANDATORY
from BR2_aarch64 and BR2_aarch64_be, and let arch/Config.in.arm do its
job. What arch/Config.in.arm does is currently incorrect, but it will
be fixed in a separate commit.
