- Do I have a hardware fault on the PW1 board – maybe an EMMC hardware fault?

Take my words with a grain of salt, I'm not an expert, just did some grepping/reading of sources and googling.
Your error happened in phase of internal storage initialization. CPU sent command to storage and polled DAT0 line of storage's interface to wait when "busy" (busy with command execution) signal ends. And after 25 seconds timeout, waiting was stopped with timeout error (number
-19 is defined in source as TIMEOUT).
Here PW1 owner got at least after storage initialization stage by using precompiled U-Boot from this forum, so the problem is not in wrong U-Boot, I think.
