Message-Id: <1395735604-26706-17-git-send-email-lee.jones@linaro.org> Date: Tue, 25 Mar 2014 08:19:33 +0000 From: Lee Jones <lee.jones@...aro.org> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Cc: lee.jones@...aro.org, kernel@...inux.com, computersforpeace@...il.com, linux-mtd@...ts.infradead.org, dwmw2@...radead.org, angus.clark@...com, pekon@...com Subject: [RFC 16/47] mtd: nand: stm_nand_bch: derive some working variables for latter use A few of the working variables can either be taken or derived from existing knowledge about the connected chip. Rather than attempt to provide each specification manually, here we make assumptions based on information already obtained.
