The OpenRISC Linux port is fully functional and has been tracking upstream since 2.6.35. There are, however, remaining items to be completed within the coming months. Here's a list of known-to-be-less-than-stellar items that are due for investigation shortly, i.e. our TODO list: -- Implement the rest of the DMA API... dma_map_sg, etc. -- Consolidate usage of memblock and bootmem... move everything over to memblock. -- Finish the renaming cleanup... there are references to or32 in the code which was an older name for the architecture. The name we've settled on is or1k and this change is slowly trickling through the stack. For the time being, or32 is equivalent to or1k. -- Implement optimized version of memcpy and memset
