de45322924 support EXTINT[4:23] as interrupt sources. They are cascaded to 
IRQ4 (EXTINT[4:7]) and 5 (EXTINT[8:23]). ssextio driver handles these interrupts.

13543d215c move some definitions of register block size from s3c24[10]0reg.h 
to s3c24x0reg.h when they are same for S3C2410 and 2400, and rename them as
S3C24X0_FOO_SIZE.

1df8bfd121 Samsung's S3C2800 and S3C24[10]0 CPUs have same built-in UART block, 
but there are very small diffs in register definitions.  For that, add
new options SSCOM_S3C{2800,2410,2400} and include appropriate
s3c*reg.h.

SSCOM_S3C2410 is also needed for interrupt controller differences.

b80cc89773 tweak to share s3c2xx0_intr.c for S3C2800 and S3C2410. 
move init_interrupt_masks() from s3c2xx0_intr.c to s3c2800_intr.c, since
it doesn't work for S3C2410.

7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only 
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

+ Don't clear interrupt pending bits for IIC in interrupt handler.
  Since clearing these bits starts next IIC transmission immediately,
  IIC driver should handle these.
