From d6fed9e9fc5eefae5be0ecf222bac7e7496e8e74 Mon Sep 17 00:00:00 2001 From: Alexander Clouter Date: Mon, 11 May 2009 19:28:01 +0100 Subject: mtd: extend plat_nand for (read|write)_buf This patch adds (write|read)_buf callbacks to plat_nand. The NAND on the TS-7800 provisioned by the FPGA allows readw() and readl() to be used which gives a 2.5x speed up. To be able to use this from the plat_nand driver a hook for read_buf (and also write_buf whilst we are in there) need to be made available. This patch adds the hook.
