This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM. The Flash device is connected to GPMC controller on chip-select[0] and accessed as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and is CFI compatible.
As multiple devices are share GPMC pins on this board, so following board settings are required to detect NOR device: SW5.1 (NAND_BOOTn) = OFF (logic-1) SW5.2 (NOR_BOOTn) = ON (logic-0) /* Active-low */ SW5.3 (eMMC_BOOTn) = OFF (logic-1) SW5.4 (QSPI_BOOTn) = OFF (logic-1)
And also set appropriate SYSBOOT configurations: SW3.1 (SYSBOOT[ 8])= ON (logic-1) /* selects SYS_CLK1 speed */ SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */ SW3.3 (SYSBOOT[10])= ON (logic-1) /* wait-pin monitoring = enabled */ SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */ SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */ SW3.6 (SYSBOOT[13])= ON (logic-1) /* device bus-width: 1(x16) */ SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */ SW3.8 (SYSBOOT[15])= ON (logic-1) /* reserved */
Also, following changes are required to enable NOR Flash support in dra7xx_evm board profile: diff --git a/boards.cfg b/boards.cfg -Active arm armv7 omap5 ti dra7xx dra7xx_evm dra7xx_evm:CONS_INDEX=1 Lokesh Vutla lokeshvutla@ti.com +Active arm armv7 omap5 ti dra7xx dra7xx_evm dra7xx_evm:CONS_INDEX=1,NOR Lokesh Vutla lokeshvutla@ti.com
