briggs 3ce3697584 Add bus_space_*_stream_N functions. 2000-07-31 22:40:25 +00:00
briggs 2cc07c0541 Add a DIAGNOSTIC panic if (count-using) bus_space macros are called with
a count of zero.  Some drivers do this accidentally and some bus_space
implementations will fail if count is passed as zero (they are set up in
a do-{}-while structure).

briggs f5882c7ffa Make sure that bus_space read/write functions that take a count will not be
called if count is zero.  The smc91cxx driver, for example, may try to call
bus_space_write_multi_2() with a count of 0.

briggs 9c85d4dc6a Add byte-swap and stride options to bus_space. Allocate as normal, then
call mac68k_bus_space_handle_swapped() or mac68k_bus_space_handle_set_stride().
Stride is untested.  Swapped code works for SMC ethernet.

drochner 8eb798e603 define a "BUS_SPACE_MAP_PREFETCHABLE" flag which basically means that
device accesses are idempotent (but should not be cached by the CPU)

drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context,
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

briggs 1082c49b69 Fix PR port-mac68k/6665 from Paul Goyette with some minor mods.
Cast values is bus_space macros to the appropriate types so we end up
with valid assembly.

scottr da5ce9387c Remove semicolons from the end of bus_space_*_multi_*(). From Ken Nakata
in PR 5965.

scottr 5b4a54759d Conform to spec, and make bus_space_copy() handle overlapping copies.
From Jason Thorpe.

scottr 5e77023e13 The bus space tag really isn't used; stop the compiler from complaining. 1997-02-24 05:55:14 +00:00
scottr 7524900a0f Remove niggles that made it into the copyright, and correct the
license terms (added Jason Thorpe).

scottr 5c8de7766a Implement bus_space_set_multi_N(), bus_space_set_region_N(), and
bus_space_copy_N().  Bus space support is now complete.

scottr 6066941306 Add prototypes for bus_space_alloc() and bus_space_free() 1997-02-14 06:02:57 +00:00
scottr 2a2a70d39c Initialize and use extent manager for bus space mapping functions.
Tweak bus_space_{tag,handle}_t types slightly to facilitate this.
1997-02-11 07:37:41 +00:00
scottr f042e543c9 Implement basic bus space access macros/functions.
Note:  we currently do not use the extent manager.
