that were causing the runtime and STL libraries to see different versions of
various classes and functions when libstdc++ is used as a filter.
Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in
-STABLE for testing and is not used by anything unless explicitly enabled by
the end user. No default compiler configurations use it.
libc++ will need to be recompiled after this change. make buildworld will do
this automatically, but make in lib/libc++ will not necessarily work unless the
new libcxxrt is installed first.

bug in old versions of QEMU (and Xen, and other places using QEMU code).
On those buggy emulated UARTs, the "TX idle" interrupt gets lost; with
this workaround, we spinwait for the TX to happen and then send ourselves
the interrupt. It's ugly but it works, while minimizing the impact on
the code for the !broken_txfifo case.

media has one already, copy it in lieu of leaving things blank. This
reduces the foot-shooting potential for PXE installs that immediately
add packages.
In all the routines that loop through a range of virtual addresses, the loop
is controlled by subtracting the cache line size from the total length of the
request. After the subtract, a 'bpl' instruction was used, which branches if
the result of the subtraction is zero or greater, but we need to exit the
loop when the count hits zero. Thus, all the bpl instructions in those loops
have been changed to 'bhi' (branch if greater than zero).
In addition, the two routines that walk through the cache using set-and-index
were correct, but confusing. The loop control for those has been simplified,
just so that it's easier to see by examination that the code is correct.
Routines for other arm architectures and generations still have the bpl
instruction, but compensate for the off-by-one situation by decrementing
the count register by one before entering the loop.

If a BUSDMA load operation results in a single segment which
is greater than the PAGE_SIZE, the USB computed physical
addresses will not be correct. Make sure that the first
segment is unfolded like the sub-sequent segments are into
USB_PAGE_SIZE big ranges.

This adds support for version 10, revision 01, but it should also work
without changes for the 0901 model, at least until we get drivers for the

Many users contributed to and tested the various patchsets floating around
for the past year that have eventually evolved into this checkin, most notably

so that we don't need an empty implementation of it for every Marvell platform
that has no PCI. This allows the removal of the SheevaPlug-specific stub and
config files, and eliminates the need to add similar stubs for future models.
Marvell platforms that do expose PCI are compiled with 'device pci' which
causes the real (non-weak) implementation in dev/fdt/fdt_pci.c to be used.
