There are two problems in the current timeout loop implementation:
1. In case initial test failing, there will always be a delay of 1 ms
2. The delay duration is not tunableThe new implementation addresses both these limitations.

smi_read_sr fails sometimes because of TFF not getting set within assumed time.
This condition may arise because of, for example, smi memory being in a erase
mode.This fix is to enable reading the status register until timeout.

SMI is the serial memory interface controller provided by ST.
Earlier, a driver exists in the u-boot source code for the SMI IP. However, it
was specific to spear platforms. This commit converts the same driver to a more
generic driver. As a result, the driver files are renamed to st_smi.c and
st_smi.h and moved into drivers/mtd folder for reusability by other platforms
using smi controller peripheral.Signed-off-by: Vipin Kumar

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.NOTE: This patch depends on:

This replacement causes 4KB page size devices to work properly with u-boot.
The old ONENAND_IS_MLC() behavior has been preserved by explicit
setting of ONENAND_HAS_4KB_PAGE for those devices.This change makes the onenand_base.c file more resembling the respective
kernel sources.Signed-off-by: Lukasz Majewski

Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in
fsl_ifc_run_command() during ECC status verification. Also this sector is passed
to is_blank() for blank checking. It is wrong at first place because
is_blank()'s implementation checks for Page size and OOB area size.
is_blank() should be called per page for main and OOB area verification.Variables name are redefined to avoid confusion between buffer and ecc sector.

This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5.
It breaks boards that currently rely on soft-ecc, as pointed out here:
http://patchwork.ozlabs.org/patch/140872/The reverted patch should be resubmitted with documentation, and with the
CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could
start by looking at what NAND driver the board selects, and whether
that driver ever asks for soft ECC.Signed-off-by: Scott Wood
