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

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48Z

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

clk: add sandbox test for bulk API

2018-04-10T19:18:56Z

This patch adds the bulk clock API tests for the sandbox test suite. It's very similar to the main test but only uses the _bulk() API and checks if the clocks are correctly enabled/disabled. Signed-off-by: Neil Armstrong Reviewed-by: Simon Glass

reset: add sandbox test for bulk API

2018-04-10T15:52:16Z

This patch adds the bulk reset API tests for the sandbox test suite. Unlike the main test, it also check the "other" reset signal using the bulk API and checks if the resets are correctly asserted/deasserted. To allow the bulk API to work, and avoid changing the DT, the number of resets of the sandbox reset controller has been bumped to 101 for the "other" reset line to be valid.

core: ofnode: Fix translation for #size-cells == 0

2018-04-01T14:19:10Z

Commit 286ede6 ("drivers: core: Add translation in live tree case") made dev_get_addr always use proper bus translations for addresses read from the device tree. But this leads to problems with certain busses, e.g. I2C busses, which run into an error during translation, and hence stop working. It turns out that of_translate_address() and fdt_translate_address() stop the address translation with an error when they're asked to translate addresses for busses where #size-cells == 0 (comment from drivers/core/of_addr.c): * Note: We consider that crossing any level with #size-cells == 0 to mean * that translation is impossible (that is we are not dealing with a value * that can be mapped to a cpu physical address). This is not really specified * that way, but this is traditionally the way IBM at least do things To fix this case, we check in both the live-tree and non-live tree-case, whether the bus of the device whose address is about to be translated has size-cell size zero. If this is the case, we just read the address as a plain integer and return it, and only apply bus translations if the size-cell size if greater than zero.

libfdt: move headers to and

2018-03-05T15:16:28Z

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 -> #include #include -> #include Reported-by: Thomas Petazzoni Signed-off-by: Masahiro Yamada

sandbox: Add 64-bit sandbox

2018-02-18T22:53:48Z

To debug device tree issues involving 32- and 64-bit platforms, it is useful to have a generic 64-bit platform available. Add a version of the sandbox that uses 64-bit integers for its physical addresses as well as a modified device tree.

sandbox: Rename 'num-gpios' property to avoid dtc warning

2018-02-18T22:53:32Z

At present dtc produces these warnings when compiling sandbox: arch/sandbox/dts/test.dtb: Warning (gpios_property): Could not get phandle node for /base-gpios:num-gpios(cell 0) arch/sandbox/dts/test.dtb: Warning (gpios_property): Missing property '#gpio-cells' in node /reset-ctl or bad phandle (referred from /extra-gpios:num-gpios[0]) Both are due to it assuming that the 'num-gpios' property holds a phandle pointing to a GPIO node. To avoid these warnings, rename the sandbox property so that it does not include the string 'gpios'. Signed-off-by: Simon Glass

fdt: Implement weak arch_fixup_fdt()

2018-02-18T19:53:38Z

Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.
