Subject: [PATCH] ARM: qcom_defconfig: Enable MAILBOX
Date: Thu, 6 Sep 2018 21:44:48 -0700 [thread overview]
Message-ID: <1536295488-12296-1-git-send-email-frowand.list@gmail.com> (raw)
From: Frank Rowand <frank.rowand@sony.com>
Problem:
ab460a2e72da ("rpmsg: qcom_smd: Access APCS through mailbox framework"
added a "depends on MAILBOX") to RPMSG_QCOM_SMD, thus RPMSG_QCOM_SMD
becomes unset since MAILBOX was not enabled in qcom_defconfig and is
not otherwise selected for the dragonboard. When the resulting
kernel is booted the mmc device which contains the root file system
is not available.
Fix:
add CONFIG_MAILBOX to qcom_defconfig
Fixes: ab460a2e72da ("rpmsg: qcom_smd: Access APCS through mailbox framework"
added a "depends on MAILBOX")

Bjorn suggested that multi_v7_defconfig might need this same fix
but I don't have a target to test on so I have not included that
change in this patch
Tested on Qualcomm APQ8074 Dragonboard
