Subject: [PATCH 3/3] ARM: Add CLPS711X architecture
Date: Thu,  4 Oct 2012 16:37:01 +0400	[thread overview]
Message-ID: <1349354221-28409-3-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1349354221-28409-1-git-send-email-shc_work@mail.ru>

This patch adds new architecture (CLPS711X) into barebox.
The core-logic functionality of the device is built around an ARM720T
processor running at clock speeds up to 90 MHz and 74 MHz.
Patch also adds a generic board support (CLEP7212, Linux ARM ID=91) and
serial driver for this CPU.
