These patches add support for the SEGA Dreamcast VMU and clean up the maple bus driver, allowing it to support block devices and ensuring it supports concurrent reads and writes eg no more mixing up which thread locks and unlocks a mutex etc. A consequential fix for the maple keyboard driver is also attached. The VMU is added as an MTD (mapping) device. It's flash but its is also "smart" so could have conceivably been added as a general block device but it transpires that as well as actually being based on flash, it displays behaviour on plugging and unplugging and on writing that make the MTD block layer a good fit (namely the MTD block layer's insistence on carrying on after a perceived hotplug event). I posted an earlier set of patches in Spring 2008 and given the difficulties with them these are posted here for review and comment rather than as a simple request for inclusion as is.
