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> 2018-05-07 06:58:06 +09:00			`# SPDX-License-Identifier: GPL-2.0+`

arm: omap3: Compile clock.c with -marm option to unbreak OMAP3530 Boards with OMAP3530 SoC fail to boot since commit bd2c4522c26d5 ("ti: armv7: enable EXT support in SPL (using ti_armv7_common.h)") because it enabled the use of Thumb2 for the SPL. Experiments have shown that the deadlock happens in the prcm_init() function from 'arch/arm/mach-omap2/omap3/clock.c'. This patch enforces the compilation of clock.c source file in ARM mode and makes the deadlock disappear. We are yet to figure out the root cause of the problem. Still this is somewhat better than having non-bootable boards for years.

arm: omap: Unify get_device_type() function Refactor OMAP3/4/5 code so that we have only one get_device_type() function for all platforms. Details: - Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for OMAP4/5), so we can obtain status register in common way - For now ctrl structure for AM33xx/OMAP3 contains only status register address - Run hw_data_init() in order to assign ctrl to proper structure - Remove DEVICE_MASK and DEVICE_GP definitions as they are not used (DEVICE_TYPE_MASK and GP_DEVICE are used instead) - Guard structs in omap_common.h with #ifdefs, because otherwise including omap_common.h on non-omap4/5 board files breaks compilation Buildman script was run for all OMAP boards. Result output: arm: (for 38/616 boards) all +352.5 bss -1.4 data +3.5 rodata +300.0 spl/u-boot-spl:all +284.7 spl/u-boot-spl:data +2.2 spl/u-boot-spl:rodata +252.0 spl/u-boot-spl:text +30.5 text +50.4 (no errors to report) Tested on AM57x EVM and BeagleBoard xM.

OMAP3 SPL: Add identify_nand_chip function A number of boards are populated with a PoP chip for both DDR and NAND memory. Other boards may simply use this as an easy way to identify board revs. So we provide a function that can be called early to reset the NAND chip and return the result of NAND_CMD_READID. All of this code is put into spl_id_nand.c and controlled via CONFIG_SPL_OMAP3_ID_NAND. Signed-off-by: Tom Rini <trini@ti.com> 2011-11-18 21:48:07 +09:00			`ifdef CONFIG_SPL_BUILD`
