This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.

include/configs/tegra-common.h now holds common config options
for Tegra SoCs.

Signed-off-by: Tom Warren <twarren@nvidia.com>

V2:
* Move pinmux_init to cardhu.c, move pinmux-config header here, too.
* tegra-common.h holds CONFIG options/defines commmon to all Tegra SoCs.
V3:
* Remove REALTEK HDA section in pinmux-config header
* Use 408MHz UART clock on T30 (still 216MHz on T20)
* Remove CONFIG_SYS_CPU_OSC_FREQUENCY (unused)
* Move MEM_LAYOUT_ENV settings to tegraXX-common.h

+ * kernel_addr_r must be within the first 128M of RAM in order for the
+ *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will

+ *   somewhere else before decompression. Similarly, the address of any other
+ *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
+ *   this up to 16M allows for a sizable kernel to be decompressed below the
+ *   compressed load address.
+ *
+ * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for

+ *
+ * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
