From 34a82443b79dcda4304b229d555586296da40c16 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 30 Jul 2008 12:35:05 -0700 Subject: [MTD] dataflash OTP support Now that we can tell when we have one of the newer DataFlash chips, optionally expose the 128 bytes of OTP memory they provide. Tested on at45db642 revision B and D chips. Switch mtdchar over to a generic HAVE_MTD_OTP flag instead of adding another #ifdef for each type of chip whose driver has OTP support.
