2010-08-05	MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_phys	David VomLehn
	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.

2009-12-17	MIPS: PowerTV: Base files for Cisco PowerTV platform	David VomLehn
	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.
