2008-01-29[MIPS] Use correct dma flushing in dma_cache_sync()Thomas Bogendoerfer
Not cache coherent R10k systems (like IP28) need to do real cache invalidates in dma_cache_sync(). Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-11-26[MIPS] 64-bit Sibyte kernels need DMA32.Ralf Baechle
Sibyte SOCs only have 32-bit PCI. Due to the sparse use of the address space only the first 1GB of memory is mapped at physical addresses below 1GB. If a system has more than 1GB of memory 32-bit DMA will not be able to reach all of it. For now this patch is good enough to keep Sibyte users happy but it seems eventually something like swiotlb will be needed for Sibyte. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-10-11[MIPS] Allow hardwiring of the CPU type to a single type for optimization.Ralf Baechle
This saves a few k on systems which only ever ship with a single CPU type. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-03-24[MIPS] Always use virt_to_phys() when translating kernel addressesFranck Bui-Huu
This patch fixes two places where we used plain 'x - PAGE_OFFSET' to achieve virtual to physical address convertions. This type of convertion is no more allowed since commit 6f284a2ce7b8bc49cb8455b1763357897a899abb.

2007-02-13[MIPS] Unify dma-{coherent,noncoherent.ip27,ip32}Ralf Baechle
Platforms will now have to supply a function dma_device_is_coherent which returns if a particular device participates in the coherence domain. For most platforms this function will always return 0 or 1. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
