* ARM: tegra: Add Tegra AHB driverHiroshi DOYU2012-05-081-2/+2
| | | | | | | | | | | | | | | | | | | Tegra AHB Bus conforms to the AMBA Specification (Rev 2.0) Advanced High-performance Bus (AHB) architecture. The AHB Arbiter controls AHB bus master arbitration. This effectively forms a second level of arbitration for access to the memory controller through the AHB Slave Memory device. The AHB pre-fetch logic can be configured to enhance performance for devices doing sequential access. Each AHB master is assigned to either the high or low priority bin. Both Tegra20/30 have this AHB bus. Some of configuration params could be passed from DT too if needed.
