83d9fd40d5 Make the default FDT implementation of platform_mp_setmaxid use the cpu 
nodes from the DTB by default. This will allow us to enumerate the CPUs
without hard coding the CPU count into code.

6c925b9c81 All armv6 platforms have the same implementation of platform_lastaddr. 
Replace them with a default handler that returns devmap_lastaddr.

c35b5d8372 Remove bus_dma_get_range and bus_dma_get_range_nb on armv6. We only need 
this on a few earlier arm SoCs.

e94f204a32 While gem5 is not qemu, we treat it as "simulators" or "virtual environments". 
Add the needed hardcoded gem5 attachments for the UART there, re-using all
the other bits.

cca48a59de Add a MULTIDELAY option to allow the ARM kernel to have multiple DELAY 
implementations. Early in the boot the kernel will use an approximate,
however after the timer has been probed it will switch to a more accurate
implementation.

30b72b6871 Move arm's devmap to some generic place, so it can be used 
by other architectures.

a19c0b37e9 Add SMP support to the ARM PLATFORM code. This will allow us to have 
different methods to start the secondary cores in a kernel built for
multiple SoCs, e.g. with the Allwinner A20 and A31.

42f0d1fa49 Add support for the QEMU virt SoC. This is a SoC built depending on the 
command line arguments passed in. It will then generate a dtb on the fly,
as such no dts will be added as it may be incorrect.
