The second part is the actual IP30 Patch that makes these beasts boot.  Assuming 
you've already lit incense candles and sacrificed a PC to the MIPS Gods above.

There's one change that probably needs good scrutiny, as it changes a value in 
dma-default.c, and this'll affect other systems:

-       return plat_map_dma_mem_page(dev, page) + offset;
+       return plat_map_dma_mem_page(dev, page, size) + offset;
  }


It's used because IP30's implementation of plat_map_dma_mem_page passes the 
'size' var to a few functions, ultimately leading to IP30's version of 
pdev_to_baddr, where it checks to make sure we're not above a certain memory 
limit (2GB) that could cause problems with DMA & PCI (I think - it's been awhile).

That's just one example, though.  There's probably more, but I've mostly done 
forward ports, and haven't really messed with re-writing much.  Hence why I'd 
like to ask others to look, poke, prod, compile, and boot, and see if they have 
other suggestions for improving and fixing this up.

Thanks!,
