* dm: Emit the arch_cpu_init_dm() even only before relocationSimon Glass2023-05-111-1/+1
| | | | | | | | | | | | The original function was only called once, before relocation. The new one is called again after relocation. This was not the intent of the original call. Fix this by renaming and updating the calling logic. With this, chromebook_link64 makes it through SPL.

* event: Correct dependencies on the EVENT frameworkTom Rini2023-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The event framework is just that, a framework. Enabling it by itself does nothing, so we shouldn't ask the user about it. Reword (and correct typos) around this the option and help text. This also applies to DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be visible to the user to select, when EVENT is selected. With this, it's time to address the larger problems. When functionality uses events, typically via EVENT_SPY, the appropriate framework then must be select'd and NOT imply'd. As the functionality will cease to work (and so, platforms will fail to boot) this is non-optional and where select is appropriate. Audit the current users of EVENT_SPY to have a more fine-grained approach to select'ing the framework where used. Also ensure the current users of event_register and also select EVENT_DYNAMIC.

* dm: treewide: Use uclass_first_device_err when accessing one deviceMichal Suchanek2022-10-171-3/+1
| | | | | | | | | | | | | | | | | | There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch.

* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-132-2/+2
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>
