extern paddr_t physical_start, physical_end;

Fix _bus_dmamem_alloc_range function declaration - low and high are
paddr_t

Sync with HEAD.

Obey __HAVE_BUS_SPACE_8

Add missing prototypes for __bs_c(f,_bs_sm_?_swap)

(implementations of these already exist for aarch64)

Mostly merge changes from HEAD upto 20200411

Add KASAN-DMA support on aarch64, same as amd64. Discussed with skrll@.

Remove the _BUS_DMAMAP_COHERENT optimisation in the bus_dmamap_sync macro
as the real function performs memory barriers now.

Sync with HEAD.  77 conflicts resolved - all of them $NetBSD$

Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Make multiple inclusion symbols always start with _ARM_ (not _ARM32_ or
_MACHINE_).

Pullup from HEAD:
Cortex needs ._dmamap_sync_post for BUS_DMASYNC_POSTREAD

Cortex needs ._dmamap_sync_post for BUS_DMASYNC_POSTREAD

Merge improved arm support (especially Cortex) from HEAD
including OMAP and BCM53xx support.

Make IS_BOUNCING a map flag and use it to simplify code and to avoid calling
the sync routines if (COHERENT|IS_BOUNCING) == COHERENT.  (this eeks out a
little bit more performance).

Add bounce buffer support for ARM bus_dma(9).  Add macros to help initialize
bus_dma_tag structures.

s/u_int*_t/ -> uint_*_t
Add swap variants for many accessors.

Per discussion at
<http://mail-index.netbsd.org/tech-kern/2010/04/02/msg007941.html>,
divide each machine's bus.h into bus_defs.h (constants & data types)
and bus_funcs.h (macro implementations of bus_space(9) routines and MD
prototypes).

Note that some bus_space(9) routines' implementation will move to .c
files from inline subroutines or macros in .h files.

I've only made the split for machine architectures where there is PCI.
All of the non-PCI-having architectures will require a similar split.

These #include files are not referenced by any (committed) Makefiles or
header files, yet.  Changes to Makefiles, to <sys/bus.h>, and to some
more machine-dependent files will dribble in before I throw the switch.
