Subject: [PATCH 12/12] firmware: arm_scpi: improve info message for pre-1.0 firmware
Date: Tue, 5 Dec 2017 23:17:19 +0100	[thread overview]
Message-ID: <587dc762-ab75-e349-87e7-c3ed0c42cd4a@gmail.com> (raw)
In-Reply-To: <99220c79-8b35-2978-11d1-6d101ccb6772@gmail.com>

On legacy pre-1.0 firmware versions so far the following message is
printed which may cause some confusion:
SCP Protocol 0.0 Firmware 0.0.0 version

Therefore replace the message with the following if firmware doesn't
provide usable version information:
SCP Protocol legacy pre-1.0 firmware
