Date: Thu, 20 Mar 2014 09:20:43 +0000 From: Lee Jones <lee.jones@...aro.org> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, computersforpeace@...il.com Cc: linux-mtd@...ts.infradead.org, dwmw2@...radead.org, Angus.Clark@...com, Lee Jones <lee.jones@...aro.org> Subject: [PATCH v6 11/36] mtd: st_spi_fsm: Use device size to determine address width Take some known parameters, namely size and number of sectors and use them to determine weather a device can support 32bit addressing or not. If it can, set the associated flash capability flag for latter use.
