u-boot.git/include/event.h, branch v2022.10 Unnamed repository; edit this file 'description' to name the repository. event: Add an event for device tree fixups 2022-08-12T12:17:11+00:00 Simon Glass sjg@chromium.org 2022-07-30T21:52:31+00:00 98887ab802e4118e7c813e5e052678772fa1b3a8 At present there is a confusing array of functions that handle the device tree fix-ups needed for booting an OS. We should be able to switch to using events to clean this up. As a first step, create a new event type and call it from the standard place. Note that this event uses the ofnode interface only, since this can support live tree which is more efficient when making lots of updates. Signed-off-by: Simon Glass <sjg@chromium.org>

event: Change EVENT_SPY to global 2022-08-12T12:17:11+00:00 Simon Glass sjg@chromium.org 2022-07-30T21:52:30+00:00 569524741a01e1a96fc2b75dd7e5d12e41ce6c2b This creates static records at present, but it causes a problem with clang and LTO: the linker list records are sometimes dropped from the image. Fix this by making the records global. Update to use __used while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>

event: fix static events for CONFIG_NEEDS_MANUAL_RELOC 2022-06-06T22:01:20+00:00 Ovidiu Panait ovpanait@gmail.com 2022-05-15T18:40:29+00:00 cebc8161708e357758c407eaa79a8cd66ee68fde Static events do not currently work post-relocation for boards that enable CONFIG_NEEDS_MANUAL_RELOC. Relocate event handler pointers for all event spies to fix this. Tested on Microblaze. Signed-off-by: Ovidiu Panait <ovpanait@gmail.com>

Also add a way to 'spy' on events, thus allowing 'hooks' to be created. Use a linker list for static events, which we can use to replace functions like arch_cpu_init_f().
