every architecture's busdma_machdep.c. It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code. The MD busdma is then given a chance to do any final processing
in the complete() callback.
The cam changes unify the bus_dmamap_load* handling in cam drivers.
The arm and mips implementations are updated to track virtual
addresses for sync(). Previously this was done in a type specific
way. Now it is done in a generic way by recording the list of
virtuals in the map.

The changes are:
- the microcore code loaded into the NAE has to be byteswapped
in LE
- the descriptors in memory for a P2P NAE descriptor has to be
byteswapped in LE
- the m_data pointer is already cacheline aligned, so the
unnecessary m_adj to cacheline size can be removed
- fix mask used to obtain physical address from the Tx freeback
descriptor
- fix a compile error in code under #ifdef

Support few more versions of board firmware. In case the security
block is disabled, enable it at boot. Also increase the excluded
memory region to cover the area used by the firmware to initialize
devices.
Update the function xlp_pcib_hardware_swap_enable() to do nothing
when BYTE_ORDER is not BIG_ENDIAN. PCIe hardware swap is not requred
in little-endian mode as the endianness matches that of CPU.
Write FDT attachment for the Terasic MTL (multitouch LCD) driver.
Exploit the fact that FDT allows multiple memory ranges to be
assigned to a device, giving us a cleaner description than
device.hints does.
Portions of this changeset that remove mtl from BERI device.hints and
add to DTS will be merged separately.

rather than a constant so that VM_KMEM_SIZE_MAX will scale automatically
with the kernel address space size. This is particularly important for
MIPS because the same definition is used by both 32- and 64-bit kernels.

Provided a bus_space implementation for FDT, modelled on
bus_space_generic, but with a local version of the map address
routine that does a P->V translation, as is the case with NLM's
similar routine for XLP. It's not clear to me that this is the
right solution -- possibly this belongs in simplebus -- however,
it is sufficient to get the DE4 LED driver working.

In a sign of weakness, replicate the MIPS bus_space_generic.c to
produce a new FDT version, which will perform necessary address
space translation for bus_space -- the solution used in NLM's MIPS
FDT support, but possibly not quite the right thing. This is
inconsistent with regular I/O via the nexus and the generic
bus_space, which instead perform translation via pmap_mapdev()
when a resource is activated. However, it will work while I
attempt to identify what the right way to reconcile possible
approaches.
(Another approach might be to make simplebus use Nexus's activate
routine instead of a generic one?)

Add code so that the BERI boot process can ask the kernel linker for
DTB blobs that may have been left for it by the boot loader, as done
on PowerPC and ARM. This will require both a more mature boot
loader, and more mature boot loader argument passing mechanism,
than currently supported on BERI.

* Mikrotik RouterBoard 433AH have PCI slot 18 wired to INT0 on the PCI Bus.
This is different from e.g. Atheros PB42 and Ubiquiti boards.
* Check for hint hint.pcib.0.baseslot=X, where X is number of base slot;
* If hint not supplied print a warning and use default AR71XX_PCI_BASE_SLOT;

FDT headers can't be included if the kernel is compiled without
FDT support, due to dependence on generated kobj headers. BERI
supports both FDT and non-FDT kernels.

o) Print board information from sysinfo after consoles have been initialized

o) Use cvmx_safe_printf and platform_reset rather than panic when doing very

o) Get rid of the global octeon_bootinfo.

class. Previously, the allocation was also allowed to completely drain
the reserve of the free pages, being translated to VM_ALLOC_INTERRUPT
request class for vm_page_alloc() and similar functions.
Allow the caller of malloc* to request the 'deep drain' semantic by
providing M_USE_RESERVE flag, now translated to VM_ALLOC_INTERRUPT
class. Previously, it resulted in less aggressive VM_ALLOC_SYSTEM
allocation class.
Centralize the translation of the M_* malloc(9) flags in the single
inline function malloc2vm_flags().
