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>

DA8xx: add generic GPIO driver Add a generic GPIO driver for the DaVinci DA8xx processors. It is turned on by defining CONFIG_DA8XX_GPIO and fulfills the generic GPIO interface specified in <asm/gpio.h> . The driver has support for both manipulating GPIO pins as well as automatically configuring the pin multiplexor registers to set the pin function to GPIO.

dm: core: Create a new header file for 'compat' features At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

common: Drop asm/global_data.h from common header Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

DM: GPIO: Fix da8xx GPIO indexing over GPIO 32 The GPIO banks are broken up into two 16-bit registers for each bank set. Unfortunately, the math that determines how to shift blindly shifted by the number of the gpio. This worked for gpio numbers under 32, but higher gpio's are broken. This fixes the gpio index, so the bank is passed and the shift amount within the register is passed now instead of the gpio number.

dm: gpio: Allow control of GPIO uclass in SPL At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL.

drivers: rename drivers to match compatible string When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.
