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> 2018-05-06 21:58:06 +00:00			`// SPDX-License-Identifier: GPL-2.0+`
rockchip: Add basic support for firefly-rk3288 The Firefly RK3288 is a suitable target board for initial mainline Rockchip support. It includes a good set of peripherals, a recent SoC and it is readily available. This adds only some basic files required to allow the baord to display a serial message in SPL and hang.

common: Move hang() to the same header as panic() At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

rockchip: rk3288: move setup_led() to firefly-rk3288 Only firefly-rk3288 has the dts node "u-boot,boot-led", while CONFIG_SPL_LED is not enable, move code to firefly-rk3288 now in case someone need this code. Signed-off-by: Kever Yang <kever.yang@rock-chips.com> 2019-07-22 11:59:24 +00:00
