X-Git-Tag: v3.12-rc1~8388^2~68^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2c5f674339d5e4c02cca7af13ec02bd9b5a96b60;p=kernel%2Fkernel-generic.git sh: Establish a SuperHyway<->PCIe window mapping on SH7786 PCIe. This bumps up the low address to match the physical memory windows for SHway<->PCIe transfers. The previous implementation was banking on a 1:1 virt<->phys SHway mapping, which doesn't apply here.
