* Implement bus_set/get/delete_resource for pci. * Change the hack used on the alpha for mapping devices into DENSE or BWX memory spaces to a simpler one. Its still a hack and should be a seperate api to explicitly map the resource. * Add $FreeBSD$ as necessary. 1999-10-14 21:38:33 +00:00			`/* $FreeBSD$ */`

Add support for SYS_RES_DENSE and SYS_RES_BWX resource types. These are equivalent to SYS_RES_MEMORY for x86 but for alpha, the rman_get_virtual() address of the resource is initialised to point into either dense-mapped or bwx-mapped space respectively, allowing direct memory pointers to be used to device memory.
