Yoshihiro Takahashi	aeda92b5f2	Add bus_space_unmap() and bus_space_free() functions to release ... a bus_space_handle allocated by bus_space_subregion().	2002-02-18 13:44:46 +00:00
Yoshihiro Takahashi	9d139b79d4	- Split the routine to initialize a bus_space_handle into the separate ... function. - Only access a bus_space_handle if the resource type is SYS_RES_MEMORY or SYS_RES_IOPORT. - Add the bus_space_subregion supports.	2002-02-17 09:16:45 +00:00
Yoshihiro Takahashi	f2eeb19063	Rewrite the pc98 bus_space stuff. ... The type of bus_space_tag_t is now a pointer to bus_space_tag structure, and the bus_space_tag structure saves pointers to functions for direct access and relocate access. Added bsh_bam member to the bus_space_handle structure, it saves access method either direct access or relocate access which is called by bus_space_* functions. Added the mecia device support. If the bs_da and bs_ra in bus tag are set NEPC_io_space_tag and NEPC_mem_space_tag respectively, new bus_space stuff changes the register of mecia automatically for 16bit access.
