Subject: NAND/TCL: prepare for common "target" reference
X-Git-Tag: v0.5.0-rc1~245
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5f3603b8ef732311516dcdad43261ca668e20626;p=openocd

NAND/TCL: prepare for common "target" reference

Every NAND driver keeps private copy of "target"
structure.
Prepare infostructure to move private "target"
copy in common/shared struct nand_device.
