    ARM: tegra: Add Tegra AHB driver · 87d0bab2
    Hiroshi DOYU authored
    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.
