Remove definitions for CACHE_LINE_SIZE and COHERENCY_UNIT which are the same
as the default.

Define COHERENCY_UNIT and CACHE_LINE_SIZE to fix arm builds.

The recent change to cpu.h and struct cpu_info needs an early definition
for the ARM_INTR_IMPLs that want to inline the spl functions and get
{,set_}curcpl() from cpu.h

move DEV_BSIZE, DEV_BSHIFT out of MD param.h, they are same on all ports

also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports
have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3
have lower MAXPHYS)

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors.  AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested.  Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

#define ALIGNBYTES __ALIGNBYTES

Make ALIGNBYTES use __ALIGNBYTES

Fix typo STACK_ALIGNBYTES -> STACKALIGNBYTES

Merge armv7 support from HEAD, specifically support for the BCM5301X
and BCM56340 evbarm kernels.

Use CPP symbols to determine the right MACHINE_ARCH

Add earm MACHINE_ARCH for __ARM_EABI__

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

Adjust ALIGNBYTES32 depending on __ARM_EABI__

COMPAT_NETBSD32 support for ARM.  Which is strange since ARM is already
32-bits.  But the newer ARM ABI AAPCS changes the alignment of 64-bit
fields so structures need to copied in and out to deal with the alignment
change.  This is a kludge but makes debugging of AAPCS support much easier.

merge to -current.

Use and define ALIGN() ALIGN_POINTER() and STACK_ALIGN() consistently,
and avoid definining them in 10 different places if not needed.

Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions
again. This was changed in sys/socket.h r1.51 to work around fallout
from the IPv6 aux data migration. It broke the historic ABI on some
platforms. This commit restores compatibility for netbsd32 code on such
platforms and provides a template for future changes to the CMSG_*
alignment. Revert PCC/Clang workarounds in postfix and tmux.

add compat hook in check for zerodev; use this hook to recognize
the old ARM /dev/zero minor mapping #ifdef COMPAT_16
fixes second part of PR kern/23581 by Richard Earnshaw

The previous commit had a #endif in the wrong place.

Purge CLSIZE, CLSIZELOG2 and MCLOFSET.
Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
  are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

* For platforms which are already ELF, remove the definition of
  MACHINE_ARCH since <arm/param.h> already sets it correctly to "arm".
* For platforms which are not yet ELF, defined MACHINE_ARCH to "arm32"
  if __ELF__ is not defined by the C preprocessor.
* In <arm/param.h>, clarify the rules about when MACHINE and
  MACHINE_ARCH are defined, and to what.  Also, for ELF platforms,
  int the non-_KERNEL case, force both MACHINE and MACHINE_ARCH to "arm",
  rather than allowing platform-specifc code to define either.

Merge Aug 24 -current into the kqueue branch.

file param.h was added on branch nathanw_sa on 2002-02-28 04:07:33 +0000

Add macros to hide the details of stack-pointer alignment.

update to -current

Clarify when/where MACHINE & MACHINE_ARCH are defined.  Add default
user-visible definitions.

Move user-visible MBUF constant here.  Define MAXPHYS.  Include DEV_BSIZE

Add a common <arm/param.h>, containing those few things that are obviously
common across all ARM systems.
