From 6f726f9584eb19e7bcef435eef8b3f8a0838e6e0 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 25 Oct 2010 18:31:48 +0200 Subject: cfi_flash: Add optional config register write to cfi-detection This patch adds the possibility to (optinally) write to the flash configuration register. The Intel style CFI chips support such a register that can be used to configure the operation mode to a non-default value. This method will be used by the t3corp board, which needs to configure the DS617 Xilinx flash for async read mode.
