board: ti: AM57xx: Add detection logic for AM57xx-evm
Current AM57xx evm supports both BeagleBoard-X15 (http://beagleboard.org/x15) and AM57xx EVM (http://www.ti.com/tool/tmdxevm5728). The AM572x EValuation Module(EVM) provides an affordable platform to quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors (AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI, machine vision, networking, medical imaging and many other industrial applications. This EVM is based on the same BeagleBoard-X15 Chassis and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's wlink8 offering. Since the EEPROM contents are compatible between the BeagleBoard-X15 and the AM57xx-evm, we add support for the detection logic to enable support for various user programmable scripting capability. NOTE: U-boot configuration is currently a superset of AM57xx evm and BeagleBoard-X15 and no additional configuration tweaking is needed. This change also sets up the stage for future support of TI AM57xx EVMs to the same base bootloader build.
