Subject: [PATCH v6 5/8] MIPS: Loongson: Add platform devices for Loongson-1A
Date: Thu, 30 Mar 2017 10:44:46 +0800 [thread overview]
Message-ID: <1490841889-13450-6-git-send-email-zhoubb@lemote.com> (raw)
In-Reply-To: <1490841889-13450-1-git-send-email-zhoubb@lemote.com>
Added basic platform devices for Loongson-1A, including serial port,
ethernet, AHCI, USB and so on.
As we known, Most of them are shared with Loongson-1B/1C,
like serial port, ethernet and so on.
But something like AHCI is only supported by Loonson-1A.
