From 33846df28fa1f4cf96a96c18142d48d813caa892 Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Wed, 11 Feb 2009 18:38:23 +0100 Subject: Add wait flags to support board/chip specific delays The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.
