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: add basic support for the Broadcom BCM2835 SoC This SoC is used in the Raspberry Pi, for example. For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

/*
bcm2836 SoC support (used in Raspberry Pi 2 model B) The bcm2835 and bcm2836 are essentially identical, except: - The CPU is an ARM1176 v.s. a quad-core Cortex-A7. - The physical address of many IO controllers has moved. Rather than introducing a whole new bcm2836 value for $(SOC) or $(ARCH), update the existing bcm2835 code to handle the minor differences, and plumb it into the ARMv7 CPU architecture.
