[U-Boot] [PATCH 3/5 v3] nios2: add Altera EP3C120 board
Thomas Chou
thomas at wytron.com.tw
Fri Apr 2 03:33:15 CEST 2010
This patch supports the Altera CycloneIII Nios dev board using
the example FPGA design at http://nioswiki.com/Linux.
This board servers as a configuration template for nios2-generic
approach. Since each fpga board can have different designs, we
will refer them as designs rather than boards. All designs can
share the same nios2-generic board directory.
To support a new design,
1. add a configuration file based on EP3C120.h.
2. include the fpga header file
3. add an entry to the NIOS2_GENERIC list in the top Makefile
Signed-off-by: Thomas Chou <thomas at wytron.com.tw>
---
trim down fpga header.
merge timer patch from Scott.
disable altera_tse to cut the dependency.
change mtdparts device name.
After nios2 next merged, this patch is only depended on
1. nios2: Fix outx/writex parameter order in io.h (from Scott)
2. nios2: add nios2-generic board (patch 1/5 in this series)
