[PATCH V1] ARM: dts: tegra: Modify pcie memory space size

Thu Jun 20 03:14:51 EDT 2013


- decrease non-prefetch memory size to 128 MB
- increase prefetch memory size to 384 MB
- above change is done because most pcie devices
  prefetch memory size requirement is quite higher
  compared to non-prefetch memory space.
