This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).
Only netbooting is supported at the moment.

FreeBSD 8-CURRENT was tested and run successfully on the following eval
boards and devices :
* DB-88F5182, DB-88F5281 (Orion based)
* DB-88F6281, RD-88F6281 (Kirkwood based)
* DB-78100 (Discovery based)

This supports 1Gbps Ethernet engine found on ARM-based SOCs (Orion, Kirkwood,
Discovery), as well as on system controllers for PowerPC processors (MV64430,
MV6446x).
The following advanced features are supported:
- multicast
- VLAN tagging
- IP/TCP/UDP checksum calculation offloading
- polling
- interrupt coalescing

the last byte of the ethernet address was not read which in turn
resulted in getting 5 out of the 6 bytes of ethernet address and
always returned ENOENT. I did not notice the bug on FPGA version
because of additional configuration data in EEPROM.

- Do not attach to Qualcomm and Novatel cards. If ignored these cards will
switch to modem mode automatically it seems.
- Reduce the priority on generic attachment to the appropriate level.
Note: A better solution is to send an eject command straightaway, but that can
be left till later.

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:
* GPIO
* Interrupt controller
* L1, L2 cache
* Timers, watchdog, RTC
* TWSI (I2C)
* UART
Other peripherals drivers will be introduced separately.

The physical page which we clear is accessed via additional temp kernel
mapping for the period of zeroing operation. However in systems with virtual
d-cache (most ARMs) when write-allocate feature is enabled, we can have
modified but unflushed content pertaining to this physical page still in the
d-cache due to its primary (pre-existing) mapping. In such scenario that
cached content upon flush is likely to overwrite [portions of] the physical
page we want to zero here..
This is a general problem with multiple virtual mappings covering the same
physical page with write-allocate and virtual d-cache: there is inherent
potential for corruptions of this kind, which are not easily resolved; it is
best policy that such multiple mappings be not allowed.

Diff minimization against ldscript.mips.
Note: CFE will not load PT_DYNAMIC segments, therefore the dynamic
sections have been placed in a PT_LOAD segment for now. This is not
too efficient in terms of memory use, they should probably get
placed in the text segment.

controllers and it seems to work just fine with at least an
add-on SAS3080X. While at it, remove the commented out ncr(4)
as it doesn't even use bus_dma(9), which isn't worth fixing
though as sym(4) already supports a superset of the controllers
driven by ncr(4).
In particular following functions KPI results modified:
- bufobj_invalbuf()
- bufsync()
and BO_SYNC() "virtual method" of the buffer objects set.
Main consumers of bufobj functions are affected by this change too and,
in particular, functions which changed their KPI are:
- vinvalbuf()
- g_vfs_close()
Due to the KPI breakage, __FreeBSD_version will be bumped in a later
commit.
As a side note, please consider just temporary the 'curthread' argument
passing to VOP_SYNC() (in bufsync()) as it will be axed out ASAP

designed drivers would never hit, but was exposed in diving into
another problem...
When expanding the devclass array, free the old memory after updating
the pointer to the new memory. For the following single race case,
this helps:
allocate new memory
copy to new memory
free old memory
<interrupt> read pointer to freed memory
update pointer to new memory
Now we do
allocate new memory
copy to new memory
update pointer to new memory
free old memory
Which closes this problem, but doesn't even begin to address the
multicpu races, which all should be covered by Giant at the moment,
but likely aren't completely.
Note: reviewers were ok with this fix, but suggested the use case
wasn't one we wanted to encourage.
