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
Changes for V4:
- Use address of HW structs (&pmc, etc.) in readl/writel
- Remove empty lines, fix mixed case hex #s & comments in header(s)
- Move board/nvidia/common/board.c UART code & header to
arch/arm/cpu/armv7/tegra2/
- Declare internal functions as static in UART code
Changes for V5:
- Move arch/arm/cpu/armv7/uart.c & board.h to drivers/serial and
rename to serial_tegra2.c
- Remove use of uart_num & UART_A/D in serial_tegra2, simplify code
Changes for V6:
- Fix uart.c add & delete in previous patchset
- Move pinmux & clock init code to common board file as per review
- Use #if defined() where possible in config files/UART code
- Drop all typedef and volatile struct declarations in header files
