Date: Tue, 18 Feb 2014 14:55:38 +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, DCG_UPD_stlinux_kernel@...t.st.com, dwmw2@...radead.org, linux-mtd@...ts.infradead.org, computersforpeace@...il.com, Angus.Clark@...com Subject: [PATCH 11/35] 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.
