cccac8a1ef Make it possible for the cdevsw d_close() driver method to detect last
close and close due to revoke(2)-like operation.

A new FLASTCLOSE flag indicates that this is last close.  FREVOKE is
set for revokes, and FNONBLOCK is also set, same as is already done
for VOP_CLOSE() call from vgonel().

The flags reuse user open(2) flags which are never stored in f_flag,
to not consume bit space in the ABI visible way.  Assert this with the
static check.

f501e6f136 If vnets are torn down while ifconfig runs an ioctl to say, destroy an
epair(4), we may hit if_detach_internal() without holding a lock and by
the time we aquire it the interface might be gone.
We should not panic() in this case as it is our fault for not holding
the lock all the way. It is not ideal to return silently without error
to user space, but other callers will all ignore the return values so
do not change the entire KPI for little benefit for now.
The ifp will be dealt with one way or another still.

616bc4f476 If bootverbose is enabled every vnet startup and virtual interface
creation will print extra lines on the console. We are generally not
interested in this (repeated) information for each VNET. Thus only
print it for the default VNET. Virtual interfaces on the base system
will remain printing information, but e.g. each loopback in each vnet
will no longer cause a "bpf attached" line.

67bcc941d0 Fix the detection of IO/memory space changing across busses when the bus
is not pci (and thus where, ironically, the whole situation is meaningless).

This was not an error in the original code, it was introduced during my
refactoring to commonize the routine.  A small change a few lines above
drove the need to make this change, and the error didn't show up on the
platforms I initially tested with.

It appears that all platforms except aarch64 are getting the file via
various header pollution, and ensuring _bus.h is included before any
openfirmware headers in every consumer of ofw/fdt stuff seems like more of
a career path than a task, so I'm taking this easy way out.

dfbf5e4bbf Add i.MX 6 IPU driver and enable it in IMX6 config
Current functionality is somewhat limited: driver assumes that there
is only one active IPU unit (IPU1) and that video output is DI0 and
video mode is 1024x768. For more advanced functionality driver requires
proper clock management which is work in progress. At the moment driver
assumes that pixel clock is configured by u-boot for 1026x768 mode.

Ian Lepore
bc7b930020 Implement OF_decode_addr() for arm. Move most of powerpc's implementation
into a new function that other platforms can share.

This creates a new ofw_reg_to_paddr() function (in a new ofw_subr.c file)
that contains most of the existing ppc implementation, mostly unchanged.
The ppc code now calls the new MI code from the MD code, then creates a
ppc-specific bus_space mapping from the results. The new arm implementation
does the same in an arm-specific way.

This also moves the declaration of OF_decode_addr() from ofw_machdep.h to
openfirm.h, except on sparc64 which uses a different function signature.

This will help all FDT platforms to set up early console access using
OF_decode_addr().

bfb14e93a2 Change KERNVIRTADDR to 0xc0000000 since the low-order bits no longer need to

Also remove a bunch of comments, most of which which have been wrong for
quite some time now, and the rest of which are mooted by these changes.  All
that's left in this file is assigning a single symbol to its cannonical

6a6d0fff18 Allow armv4/5 kernels to be loaded on any 2MB boundary, like armv6/7.
This eliminates the reliance on PHYSADDR and KERNPHYSADDR compile-time
symbols (except when the rom-copy code is enabled) by using the current
PC and the assumption that the entry-point routine is in the first 1MB
section of the text segment.

Other cleanups done:

 - Reduce the initarm() stack size back to 2K.  It got increased to
   4 * 2K when this file was supporting multicore armv6, but that
   support is now in locore-v6.S.

 - When building the temporary startup page tables, map the entire
   4GB address space as VA=PA before mapping the kernel at its loaded
   location.  This allows access to boot parameters stored somewhere
   in ram by the bootloader, regardless of where that may be.

 - When building the page table entry for supporting EARLY_PRINTF, map
   the section as uncached unbuffered, since it is presumably device
   registers.

Note that this restores the ability to use loader(8)/ubldr on armv4/5
kernels.  That was broken in r283035, the point at which ubldr started
loading an arm kernel at any 2MB boundary.

Also note that after this, there is no reason to set KERNVIRTADDR to
anything other than 0xc0000000, and no need for PHYSADDR or KERNPHYSADDR
symbols at all.
