Subject: [PATCH 3/6] MIPS: Loongson: Use firmware arguments to get board name
Date: Mon, 9 Mar 2020 16:23:23 +0800 [thread overview]
Message-ID: <1583742206-29163-4-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1583742206-29163-1-git-send-email-yangtiezhu@loongson.cn>
In order to distinguish various types of bridge chip such as AMD RS780E
or Loongson 7A1000, we can use firmware arguments to get board name.
