doc: arch: Convert README.sandbox to reST

2019-07-24T14:10:10Z

Convert plain text documentation to reStructuredText format and add it to Sphinx TOC tree. No essential content change. Signed-off-by: Bin Meng

sandbox: Add documentation on how to run valgrind

2019-07-10T22:52:58Z

U-Boot sandbox can run with valgrind to check memory allocations. Add documentation on how to do this. Signed-off-by: Simon Glass

sandbox: Allo sdl-config to be overridden

2019-07-10T22:52:58Z

When cross-compiling, sometimes sdl-config must come from a different path from the default. Add a way to override it, by adding SDL_CONFIG to the environment before building U-Boot. Signed-off-by: Simon Glass

sandbox: Move pre-console buffer out of the way of tracing

2019-04-24T02:26:43Z

These two buffers currently conflict if tracing is enabled. Move the pre-console buffer and update the documentation. Signed-off-by: Simon Glass

sandbox: Improve debugging in initcall_run_list()

2019-04-24T02:26:43Z

At present if one of the initcalls fails on sandbox the address printing is not help, e.g.: initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96) This is because U-Boot gets relocated high into memory and the relocation offset (gd->reloc_off) does not work correctly for sandbox. Add support for finding the base address of the text region (at least on Linux) and use that to set the relocation offset. This makes the output better: initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96) Then you use can use grep to see which init call failed, e.g.: $ grep 0000000000048134 u-boot.map stdio_add_devices Of course another option is to run it with a debugger such as gdb: $ gdb u-boot ... (gdb) br initcall.h:41 Breakpoint 1 at 0x4db9d: initcall.h:41. (2 locations) Note that two locations are reported, since this function is used in both board_init_f() and board_init_r().

sandbox: Add a memory map to the sandbox README

2018-11-26T13:25:35Z

We have a few things in the memory map now, so add documentation for this to avoid confusion. Also note that it is possible to run all tests now. Signed-off-by: Simon Glass

sandbox: README: use setenv ethrotate no

2018-11-21T02:14:22Z

If we want to control which network interface is actually used, we have to issue 'setenv ethrotate no'. If ethrotate is not set any interface may be used. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

sandbox: README: setting environment variables

2018-11-21T02:14:22Z

The command to set environment variables is setenv. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

sandbox: Add an explanation of the sandbox variants

2018-09-29T17:49:35Z

There are quite a few builds of sandbox now. Add information about these to the README. Signed-off-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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
