GC the unused `physadr' type, which was not able to hold a complete physical

address on 2 architectures anyhow. Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Change the ISA DMA API to take an isa_chipset_tag_t rather than
...
a struct device * corresponding to the ISA bus device. The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.
These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.
1998-06-09 00:06:54 +00:00

The ISA chipset must persist; it's required after autoconfig time.

Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG)
...
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used. If they are not, a message will be displayed on
the console.
Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed. These changes will aid debugging
of broken device drivers.
