| * sandbox: Complete migration away from os_malloc()Simon Glass2020-02-051-4/+4
| | | | | | | | | | | | | | | | | | | | Now that we can use direct access to the system malloc() in sandbox, drop the remaining uses of os_malloc(). The only one remaining now is for the RAM buffer, which we do want to be at a known address, so this is intended. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: core: Drop the inclusion of linux/compat.h in dm.hSimon Glass2020-02-056-2/+7
| | | | | | | | | | | | | | Most files don't need this header and it pulls in quite of lots of stuff, malloc() in particular. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-05460-77/+593
| | | | | | | | | | | | | | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

| * dm: core: Require users of devres to include the headerSimon Glass2020-02-05242-5/+275
| | | | | | | | | | | | | | | | | | | | At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

| | | | | | | | | | | | | | | | | | | | Sandbox currently uses SDL1.2. SDL2 has been around for quite a while and is widely supported. It has a number of useful features. It seems appropriate to move sandbox over. Update the code to use SDL2 instead of SDL1.2. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | At present there is no positive indication that U-Boot has finished sending sound data. This means that it is not possible to power down an audio codec, for example. Add a new method that is called once all sound data has been sent.

| | | | | | | | | | | | | | | | | | | | | | Some sandbox files are not built with U-Boot headers, so with the renamed malloc functions there is now no need to use the special os_... allocation functions to access the system routines.

| * dtc: add ability to make nodes conditional on them being referencedMaxime Ripard2020-02-055-0/+55

This is just a cherry-pick of the patch introducing this feature. Original commit message from Maxime: ------------------ A number of platforms have a need to reduce the number of DT nodes, mostly because of two similar constraints: the size of the DT blob, and the time it takes to parse it. As the DT is used in more and more SoCs, and by more projects, some constraints start to appear in bootloaders running from SRAM with an order of magnitude of 10kB. A typical DT is in the same order of magnitude, so any effort to reduce the blob size is welcome in such an environment. Some platforms also want to reach very fast boot time, and the time it takes to parse a typical DT starts to be noticeable. Both of these issues can be mitigated by reducing the number of nodes in the DT. The biggest provider of nodes is usually the pin controller and its subnodes, usually one for each valid pin configuration in a given SoC. Obviously, a single, fixed, set of these nodes will be used by a given board, so we can introduce a node property that will tell the DT compiler to drop the nodes when they are not referenced in the tree, and as such wouldn't be useful in the targetted system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command tpm (and tpm2) search the tpm and use it. On sandbox, there are two tpm (tpm 1.x and tpm 2.0). So the command tpm and tpm2 are always executed with the first tpm (tpm 1.x), and the command tpm2 always fails. This add a subcommand device to command tpm and command tpm2. Then the command tpm and tpm2 use the device selected with the subcommand device. To be compatible with previous behaviour, if the subcommand device is not used before a tpm (or tpm2) command, the device 0 is selected.
