reinoud 7bace466ad Initial commitment of the bus_space_mmap() functions as proposed by Jason R 
Thorpe as an extension to the bus_space(9) API.

Only the mainbus has a working mmap... iomd, podulebus and isa dont have
one yet. Its trivial to add the iomd and isa's memory part but am a bit
hessistant to add it without knowing its implications by heart.

Podulebus might be implemented in 32 bits EASI but otherwise its not really
transparent since there is AFAIK no function to explicitly read one byte or
so .. or is this implemented in a higher level ?

ARM26 and arch/arm32/dnard (Shark) kernels compile and RiscPC and Shark
kernels are tested and function OK.

Implications of other ARM systems like hpcarm and ebarm are propably
minimal or solved trivially.

it now lives in cats/isa/isa_machdep.c

matthias af667cdd42 The io offsets in arm32/isa/timerreg.h included the IO_TIMER1 offset. 
With dev/ic/i8253reg.h this is not the case.
Add IO_TIMER1 to all offsets used in inb and outb. This fixes port-arm32/13009.

tech-kern and now documented in evcnt(9).

cgd c9c2181ed9 provide an __ELF__ version of _C_FUNC and _C_LABEL, convert the assembly 
#defines in asm.h to use them, and convert code which needs to use C labels
to use _C_LABEL as well.  (I can't see any reason why the label vs. function
differentiation shouldn't be GC'd; i only added uses of _C_LABEL.)  This
should help if this port is converted to use ELF, and was checked by
compiling all kernels in arm32/conf (with some driver removals and some
MI header fixups re: common blocks) with an arm-linux ELF toolchain.

ross a1cca18262 Implementing bus_space_barrier(9)::isa_bs_barrier() with panic(9) 
does in fact get you a barrier, but it's unnecessarily drastic.
