From d55e0dabd706a5632a11d4d82c777def4fd8ce32 Mon Sep 17 00:00:00 2001 From: Andrew Gabbasov Date: Thu, 4 Jul 2013 06:27:32 -0500 Subject: mx6: Fix calculation of emi_slow clock rate This is porting of Freescale's patch from version imx_v2009.08_3.0.35_4.0.0, that fixes the obvious mistype of bits offset macro name (ACLK_EMI_PODF_OFFSET was used instead of ACLK_EMI_SLOW_PODF_OFFSET). Using the occasion, change the variable name 'emi_slow_pof' to more consistent 'emi_slow_podf'.

do echo $i = `cat $i`; done ecc_strength = 16 oobsize = 224 subpagesize = 4096 The ECC strength was not properly discovered by U-Boot causing the data written by Linux to return an -74 (EBADMSG) when read from U-Boot. This patch fixes mxs_nand_get_ecc_strength() to function in case of a NAND flash with page_data_size = 4096 and page_oob_size= 224.
