From 4d2ca9d6a0452edeaf5922cbae3b939974114214 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 25 Oct 2010 18:31:39 +0200 Subject: [PATCH] cfi_flash: Use flash_read32() in sector_erased() The function sector_erased() is modified to not use pointer access, but to use the correct accessor functions. This fixes a problem on the t3corp board with the Xilinx DS617 flash chips. Here a board specific accessor function is needed to read from flash in 32bit mode. This patch enables such an operation mode.
