Tegra30: Add common CPU (shared) files These files are used by both SPL and main U-Boot. Also made minor changes to shared Tegra code to support T30 differences. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>

Tegra30: Cardhu: Add pad config tables/code based on pinmux code Pad config registers exist in APB_MISC_GP space, and control slew rate, drive strengh, schmidt, high-speed, and low-power modes for all of the pingroups in Tegra30. This builds off of the pinmux way of constructing init tables to configure select pads (SDIOCFG, for instance) during pinmux_init(). Currently, only SDIO1CFG is changed as per the TRM to work with the SD-card slot on Cardhu. Thanks to StephenW for the suggestion/original idea.

Tegra30: Cardhu: Add pad config tables/code based on pinmux code Pad config registers exist in APB_MISC_GP space, and control slew rate, drive strengh, schmidt, high-speed, and low-power modes for all of the pingroups in Tegra30. This builds off of the pinmux way of constructing init tables to configure select pads (SDIOCFG, for instance) during pinmux_init(). Currently, only SDIO1CFG is changed as per the TRM to work with the SD-card slot on Cardhu. Thanks to StephenW for the suggestion/original idea.
