svn commit: r331141 - head/sys/dev/flash

[Ian Lepore]

Author: ian
Date: Sun Mar 18 18:58:47 2018
New Revision: 331141
URL: https://svnweb.freebsd.org/changeset/base/331141

Log:
  Add the device/chip type to the disk d_descr field, and print more info
  about the chip including the erase block size at attach time.
  
  Also add myself to the copyrights since at this point svn blame would point
  to me as the culprit for much of this.
