The following patch series adds USB 2.0 support for the Wii PowerPC
platform via the EHCI controller present in the "Hollywood" chipset
of the video game console.
v4 -> v5
- Set the default IO TLB size via the kernel command line.
This is now possible on PowerPC thanks to a recent patch by Fujita Tomonori.
- swiotlb support for the Wii is now based on top of the swiotlb-0.6
patches from Konrad Rzeszutek Wilk.
- Keeps using v4 of the USB HCD_NO_COHERENT_MEM patch
Alan: I think you are also working in a patchset to make {un}map_urb_for_dma
remember how the urb was mapped, right?
Albert Herranz (10):
swiotbl: add back swiotlb_alloc_boot()
swiotlb: make swiotlb_bounce() __weak
powerpc: add per-device dma coherent support
powerpc: add min_direct_dma_addr
USB: refactor unmap_urb_for_dma/map_urb_for_dma
USB: add HCD_NO_COHERENT_MEM host controller driver flag
wii: have generic dma coherent
