Subject: [PATCH] mailbox: ARM_MHU_V3 should depend on ARM64
Date: Wed, 29 May 2024 09:30:45 +0200
Message-Id: <e00498fccf6dcbcf63bd24a137bfc7abd1b98345.1716967720.git.geert+renesas@glider.be>

The ARM MHUv3 controller is only present on ARM64 SoCs.  Hence add a
dependency on ARM64, to prevent asking the user about this driver when
configuring a kernel for a different architecture than ARM64.

Fixes: ca1a8680b134b5e6 ("mailbox: arm_mhuv3: Add driver")

The MHUv3 documentation is unclear about whether this can be present
only on ARM64, or also on ARM.
Googling 'site:arm.com MHUv3 "aarch32"' shows no results.
Googling 'site:arm.com MHUv3 "aarch64"' does show results.
