[linux-unicore] [PATCH] unicore32: Add bfd configure support
- From: gxt@xxxxxxxxxxxxxxx
- To: linux-unicore@xxxxxxxxxxxxx
- Date: Mon, 24 Dec 2012 16:11:56 +0800
From: Guan Xuetao <gxt@xxxxxxxxxxxxxxx>
This patch adds bfd configure support based on 2.19.1, including empty
elf32-unicore32.c.
Now, configuration step can smoothly work, though only bfd is correctly
configured.
Signed-off-by: Guan Xuetao <gxt@xxxxxxxxxxxxxxx>
