Use a non CR version of the Bay Trail SoC 2. Contain at least 6 interrupt resources so that the platform_get_resource(pdev, IORESOURCE_IRQ, 5) check to workaround non CR systems which list their IPC IRQ at index 0 despite being non CR does not work 3. Despite 1. and 2. still have their IPC IRQ at index 0 rather then 5 Add a DMI quirk table to check for the few known models with this issue, so that the right IPC IRQ index is used on these systems.
