SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

ARM: omap5: add platform specific info for GPMC and ELM controllers This patch moves platform specific information for GPMC and ELM controller into separate header files, so that any derivative devices do not mess other header files. Platform specific information added into arch-xx/../hardware.h - CPU related platform specific details like base-address of GPMC and ELM Platform specific information added into arch-xx/../mem.h - Generic configs for GPMC and ELM initialization. - Hardware parameters or constrains specific to GPMC and ELM IP like; number of max number of chip-selects available Signed-off-by: Pekon Gupta <pekon@ti.com>

board/ti/dra7xx: add support for parallel NOR 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:
