Subject: [RFC 4/5] MIPS: qemu-malta: add board label
Date: Thu, 20 Dec 2012 01:29:54 +0400 [thread overview]
Message-ID: <1355952595-1432-5-git-send-email-antonynpavlov@gmail.com> (raw)
In-Reply-To: <1355952595-1432-1-git-send-email-antonynpavlov@gmail.com>
Put special Board ID at the start of bootrom (as qemu does).
The linux kernel use this board ID to determine
the MIPS board family and version, so we need this
Board ID to run linux kernel successfully.
