2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-08-16env: Rename getenv/_f() to env_get()Simon Glass
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

2014-10-29kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj
This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.
