linux v2.6.31-rc6 can not detect NEC uPD29F064115. uPD29F064115 is a 16 bit device. datasheet: http://www.cn.necel.com/memory/cn/download/M16062EJ2V0DS00.pdf A problem and fix is described as following commit, which in the main kernel tree, uPD29F064115 needs same fix. commit ca6f12c67ed19718cf37d0f531af9438de85b70c Author: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Date: Wed Jul 16 00:09:15 2008 +0900 [MTD] jedec_probe: Fix SST 16-bit chip detection The unlock_addr rework in kernel 2.6.25 breaks 16-bit SST chips. SST 39LF160 and SST 39VF1601 are both 16-bit only chip (do not have BYTE# pin) and new uaddr value is not correct for them. Add MTD_UADDR_0xAAAA_0x5555 for those chips. Tested with SST 39VF1601 chip.
