board/ti/dra7xx: add support for parallel NAND
This patch adds support for x16 NAND device (MT29F2G16AAD) connected to GPMC
chip-select[0] on DRA7xx EVM.
As GPMC pins are shared by multiple devices, so in addition to this patch
following board settings are required for NAND device detection [1]:
SW5.9 (GPMC_WPN) = OFF (logic-1)
SW5.1 (NAND_BOOTn) = ON (logic-0) /* Active-low */
SW5.2 (NOR_BOOTn) = OFF (logic-1)
SW5.3 (eMMC_BOOTn) = OFF (logic-1)
SW5.4 (QSPI_BOOTn) = OFF (logic-1)
And also set appropriate SYSBOOT configurations
SW2.1 (SYSBOOT[0]) = ON (logic-1) /* selects NAND Boot */
SW2.2 (SYSBOOT[1]) = OFF (logic-0) /* selects NAND Boot */
SW2.3 (SYSBOOT[2]) = OFF (logic-0) /* selects NAND Boot */
SW2.4 (SYSBOOT[3]) = OFF (logic-0) /* selects NAND Boot */
SW2.5 (SYSBOOT[4]) = ON (logic-1) /* selects NAND Boot */
SW2.6 (SYSBOOT[5]) = ON (logic-1) /* selects NAND Boot */
SW2.7 (SYSBOOT[6]) = OFF (logic-0) /* reserved */
SW2.8 (SYSBOOT[7]) = OFF (logic-0) /* reserved */
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: Addr/Data Muxed */
SW3.5 (SYSBOOT[12])= ON (logic-1) /* device type: Addr/Data 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 */
Following changes are required in board.cfg to enable NAND on J6-EVM:
