[commit] r757 - trunk

Author: hailfinger
Date: 2009-11-14 04:48:33 +0100 (Sat, 14 Nov 2009)
New Revision: 757

Modified:
   trunk/flashchips.c
   trunk/jedec.c
Log:
The automatic retry in write_page_write_jedec didn't retry flashing the
correct range, essentially rendering the functionality useless. This
patch simplifies the code and fixes the bug.

Thanks to Luke Dashjr for testing.

Mark Winbond W29C040P as supported.
