This series of patches adds preliminary/baseline support for NVIDIA's Tegra2 SoC. Basic CPU (AVP), RAM and UART init are covered so that the system (Harmony or Seaboard) can boot to the U-Boot serial cmd prompt.
Further support (for Cortex-A9 CPU(s), USB, SD/MMC, etc.) to follow.
Changes for V2: - Coding style cleanup - Remove mach-types.h change; wait for ARM kernel sync-up - Move serial driver changes to separate patch - Use board/nvidia/ instead of /board/tegra - Remove TRUE/FALSE defines - Use standard NS16550 register/bit defines in UART init - Change nv-common.h config file to tegra2-common.h
Changes for V3: - Use I/O accessors for Tegra2 HW MMIO register access - Allow conditional compile of UARTA/UARTD code to save space
