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> |

sandbox: Add SDL library for LCD, keyboard, audio SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

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> |

sandbox: Add SDL library for LCD, keyboard, audio SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

reset: Remove addr parameter from reset_cpu() Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <hws@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> |

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> |

sandbox: Add SDL library for LCD, keyboard, audio SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.
