* Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)Yang Hongyang2009-04-131-1/+1
| | | | | | | | | | | | | | | | This is the second go through of the old DMA_nBIT_MASK macro,and there're not so many of them left,so I put them into one patch.I hope this is the last round. After this the definition of the old DMA_nBIT_MASK macro could be removed.

| * solos: Clean up firmware loading codeDavid Woodhouse2009-01-271-136/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We no longer try to load firmware while the ATM is up and running. However, this means that we _do_ make init_module() wait for it, and it takes a long time for now (since we're using ultra-conservative code in the FPGA for that too). The inner loop which uses swahb32p() was by Simon Farnsworth. Simon has patches which migrate us to request_firmware_nowait(), for which we'll actually need to take down the ATM devices, do the upgrade, then reregister them.
