[PATCH 0/2] bus: efi: add basic ACPI bus infrastructure
Microsoft specifies an ACPI Watchdog Action Table for its server offerings that abstracts away hardware-specifics of watchdog devices. This can be an alternative to implementing many different watchdog driver in barebox for x86 H/W, as the driver is implemented in the BIOS and barebox would only need to implement the H/W. Unfortunately, I don't H/W handy that provides the WDAT table. I've implemented the ACPI bus nevertheless, so here's the patch. I haven't found anything else I'd like to do with ACPI, so I wrote a sample driver to test the API. Not sure if it should go into the tree, but I'd be in favor of adding it till there is a real user of the ACPI bus (besides devinfo).
