MIPS: PowerTV: Base files for Cisco PowerTV platform Add the Cisco Powertv cable settop box to the MIPS tree. This platform is based on a MIPS 24Kc processor with various devices integrated on the same ASIC. There are multiple models of this box, with differing configuration but the same kernel runs across the product line.

MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_phys Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm The approach taken is inspired by the sparse memory implementation: take a certain number of high-order bits off the address them, use this as an index into a table containing an offset to the desired address and add it to the original value. There is a table for mapping physical addresses to DMA addresses and another one for the reverse mapping. The table sizes depend on how fine-grained the mappings need to be; Coarser granularity less to smaller tables. On a processor with 32-bit physical and DMA addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays. Each 32-byte cache line thus covers 64 MiB of address space. Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to dma_to_phys() to align with kernel usage. [Ralf: Fixed silly build breakage due to stackoverflow warning caused by huge array on stack.] Signed-off-by: David VomLehn <dvomlehn@cisco.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1257/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

MIPS: PowerTV: Separate PowerTV USB support from non-USB code Separate USB code into a file separate from asic/asic_devices. Separating the USB code from everything else in asic/asic_devices.c goes a long way toward reducing the use of that file as a dumping ground for everything that didn't seem to fit anywhere else.
