From 346e125967c39fc25263f3071dfc88224ae843f4 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Thu, 10 Sep 2009 14:27:23 +0800 Subject: [PATCH] pxa3xx_nand: disable nand irq in initialization In some bootloader, IRQ is enabled. Writing nand triggers unexpected interrupts. So disable nand irq in initialization. After nand initialized and in working state, irq is controlled by nand driver.
