From 66712b8b460e9ba01374ca0df8aa8bcb3137e4bb Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 4 Feb 2014 12:56:18 +0400 Subject: arc: add Arcangel4 board support Arcangel4 is a FPGA-based development board that is used for prototyping and verificationof of both ARC hardware (CPUs) and software running upon CPU. This board avaialble in 2 flavours: * Little-endian (arcangel4) * Big-endian (arcangel4-be) Signed-off-by: Alexey Brodkin Cc: Vineet Gupta Cc: Francois Bedard Cc: Wolfgang Denk Cc: Heiko Schocher --- include/configs/arcangel4.h | 91 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 91 insertions(+) create mode 100644 include/configs/arcangel4.h (limited to 'include/configs/arcangel4.h') diff --git a/include/configs/arcangel4.h b/include/configs/arcangel4.h new file mode 100644 index 0000000000..4579eb97c2 --- /dev/null +++ b/include/configs/arcangel4.h @@ -0,0 +1,91 @@ +/* + * Copyright (C) 2013-2014 Synopsys, Inc.
