Excellent!  No patch includes HRCW configurations unless you (or someone
else) provides it to Wolfgang.  U-boot is self-serv[e|ing] ;-).  Having
said that, I will put it into my build and roll another patch for
Wolfgang, superseding my previous patch.  I neglected to update the
README to discuss the added _lowboot configurations which has been
bothering my conscience, so I need to add that too.

Per your previous email on the flash width/HRCW/BPS, that was my bad on
the BPS field.  I'm glad you read the manual better than me ;-).
