| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a minimal support for booting IXP4xx systems from device tree. We have to add hacks to the QMGR, NPE and notably also ethernet and watchdog drivers so that they don't crash the platform: these drivers are unconditionally starting to grab regions of statically remapped IO space with no concern of the device model or other platforms. We will go in and properly fix these drivers as we go along but for now this hack gets us to a place where we can start working on proper device tree support for these platforms.

Enabling BCM_KONA_WDT_DEBUG without BCM_KONA_WDT does not make sense, so drop the COMPILE_TEST dependency from it. This also improves menuconfig, which now properly associates BCM_KONA_WDT_DEBUG with BCM_KONA_WDT.

As a result, the default governor was always built into the kernel, even if no watchdog driver was loaded. By using "depends on" instead of "select", we are in better control, and the governors can all be built as modules. At the same time, set the default configuration option for pretimeout governors to match WATCHDOG_CORE (meaning all pretimeout governors are by default enabled if pretimeout support is enabled). The practical impact of this change is minimal. Previously, selecting a default governor automatically enabled that governor. Now, a default governor can only be selected if that governor has been enabled. Consequently, the order of governor selection is now reversed: The governor selection is now first, followed by default governor selection.

We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We leave the moduleparam.h include since the file does declare some module parameters, and leaving them as such is currently the easiest way to remain compatible with existing boot arg use cases.

Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_ALIAS is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with moduleparam.h since the file does actually declare some module parameters (i.e. boot args for non-modules).
