tegra2: Add Avionic Design Medcom support.
The Medcom is a 16:9 15" terminal that is used for patient infotainment in hospitals. Changes in v3: * Remove unused implementation of gpio_config_uart(). * Implement MMC/SD card detection. * Drop board_mmc_getcd() which is now implemented by common Tegra2 code. * Add MAINTAINERS entry. Changes in v2: * No longer override the default CONFIG_SYS_TEXT_BASE setting.
