u-boot.git/drivers/virtio, branch v2020.04 Unnamed repository; edit this file 'description' to name the repository. dm: core: Create a new header file for 'compat' features 2020-02-06T02:33:46+00:00 Simon Glass sjg@chromium.org 2020-02-03T14:36:16+00:00 336d4615f8fa774557d14f9b3245daa9e5fe3dbc 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 header 2020-02-06T02:33:46+00:00 Simon Glass sjg@chromium.org 2020-02-03T14:36:15+00:00 61b29b82683863a970fd4609a7c58512872616bc 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. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de>
