[flashrom] [commit] r805 - trunk

[svn at flashrom.org]

Author: hailfinger
Date: 2009-12-17 05:22:40 +0100 (Thu, 17 Dec 2009)
New Revision: 805

Modified:
   trunk/jedec.c
Log:
probe_jedec() checks the delay value and issues programmer_delay based
on the value except for delays between single chip_writeb.
If a chip has zero probe_delay, delays between chip_writeb should be
skipped as well.
