Bus fault error means the code tried to access invalid memory location (not assigned to any memory controller), no bus transfer acknowledge assertion within reasonable time and "machine check" exception, caused by bus monitor timeout.
To debug the U-boot code to understand which particular instruction causes this error, please look this link:
