ce4210d673 Use a magic number to know we were started from the elf wrapper. 
Add a dummy _start function to make the non-elf version of the wrapper work.

50f31d87f2 Import dummy drivers for the i80321 DMA controller and AAU. 
The DMA controller driver only knows how to do memory to memory copies, and
the AAU driver how to zero a chunk of memory.
Use them to process big (>=1KB) copying/zeroing.

56e472e2b5 Add a new arm-specific option, ARM_USE_SMALL_ALLOC. If defined, it provides 
an implementation of uma_small_alloc() which tries to preallocate memory
1MB per 1MB, and maps it into a section mapping.

f4c01f1508 Instead of using sysarch() to store-retrieve the tp, add a magic address, 
ARM_TP_ADDRESS, where the tp will be stored. On CPUs that support it, a cache
line will be allocated and locked for this address, so that it will never go
to RAM. On CPUs that does not, a page is allocated for it (it will be a bit
slower, and is wrong for SMP, but should be fine for UP).
The tp is still stored in the mdthread struct, and at each context switch,
ARM_TP_ADDRESS gets updated.

e1e6b9d3c6 - The IQ80321 has a jumper which changes the PCI device id from 4 to 8 for the 
GigE controller, so handle this.
- Use the outbound window 0 if the PCI mem requested is in its range, instead
of inconditionally use the outbound window 1.
This should be enough to get FreeBSD/arm to work on the IQ80321 board as well.

90f794aaaf If we're still running at the physical address, jump to the virtual address 
instead before calling initarm().
This removes the need to map virtual == physical in initarm().

6052fa47a9 Import partial support for the IQ31244 eval board (i80321 CPU). IQ80321 might 
work out of the box too, but I have no hardware to test.
It works well enough to go multiuser. Network works, SATA does not, as I have
no drive to test.
Thanks to Intel for sending such a board.
