The bootROM in the Armada-38x (and similar) SoC has two modes for UART boot. The first is when the normal boot media is blank (or otherwise missing the kwb header). The second is when the boot sequence has been interrupted with the magic byte sequence on the UART lines. In the first mode the bootROM routine and error code register will indicate that there was an error booting from the configured media in bits 7:0. In the second mode there is no error to indicate but the boot source is provided via bits 31:28. Handle both situations so that kwboot can be used for both boot strapping a blank board and for intercepting a regular boot sequence.
