Subject: [PATCH 1/2] mtd: bcm47xxsflash: implement ChipCommon R/W ops
Date: Sun, 24 Mar 2013 21:51:30 +0100 [thread overview]
Message-ID: <1364158291-22591-1-git-send-email-zajec5@gmail.com> (raw)
They are needed for erasing/writing. Use a magic pointers and small
functions to preapre code for adding other buses suppoer in the future
(like SSB).
