From: Antonio Borneo Date: Fri, 31 Dec 2010 11:46:02 +0000 (+0800) Subject: NAND/AT91SAM9: remove private "target" copy X-Git-Tag: v0.5.0-rc1~244 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2e1f2b50fdac6ece0d9d1cfd99cfedc36615d574;p=openocd NAND/AT91SAM9: remove private "target" copy Remove "target" form private data, and use common one in struct nand_block.
