* Get UBL Mesh Generation, Mesh Save & Mesh Load working with 32-Bit platforms * clean up read_data() and write_data() for non-LPC1768 HAL's * Get read_data() and write_data() return codes consistent All HAL's read_data() and write_data() return false if they succeed. * Get read_data() and write_data() return codes to be consistent Make read_data() and write_data() return true if an error happens. * Say UBL is now checked out on machine types in default Configuration.h file.
