Add MTD layer driver for spi, original patch from:
http://git.denx.de/?p=u-boot/u-boot-mips.git;a=commitdiff;h=bb246819cdc90493dd7089eaa51b9e639765cced

Changes from Heiko Schocher against this patch:
- Remove compile error if not defining CONFIG_SPI_FLASH_MTD:

- Add a README entry.
- Add correct writebufsize, to fit with Linux v3.14
  MTD, UBI/UBIFS sync.

Note (From Jagan): For testing raw mtd parition erase/read/write operations
using cmd_sf, sf_mtd should be required to register the spi flash device to
MTD layer but the sf_mtd_info ops were not required until and unless if we
use any flash filesystem layer say for example UBI. Due to this the foot-print
got increased ~290bytes in non-UBI case here that should be acceptible.

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.

Remove the configs that behave this way from the archs.

A few configs still remain, but that is because they only exist as
defaults and do not have a proper Kconfig entry. Those appear to be:

Patch 33fe2fb8 titled
"mmc: bcm283x: Remove get_timer_us() from mmc driver"
incorrectly replaced ad-hoc get_timer_us() function
with a plain get_timer(). The get_timer() operates in
mSec units instead of uSec though, which caused very
slow operation of the driver.

Restore the original behavior of the driver, but avoid
get_timer_us() and use timer_get_us() instead. The later
is part of the standard API.

DRA7/AM57xx devices can be operated in many different configurations.
When the SoC is supposed to support a configuration where low power mode
state may involve the SoC completely powered off and DDR is in self
refresh, SoC EMIF controller should not be the master of the reset
signal and an external entity might be in control of things.

The default configuration of Linux on TI evms involve not powering off
the voltage rails (due to various reasons including reliability concerns)
and must not allow DDR reset to be controlled by EMIF. On platforms
where external entity might control the reset signal, this configuration
will be a "dont care".

This introduces the part start and part size sub-commands. The purpose of these
is to store the start block and size of a partition in a variable, given the
device and partition number.

This allows reading raw data that fits a single partition more easily.
For instance, this could be used to figure out the start block and size of a
kernel partition when a partition table is present, given the partition number.

Without this we loose every other interrupt packet. We never noticed this

There is no harm in declaring the function prototypes even if nothing
implements them, and when CONFIG_DM_USB=y the various usb functions are
available regardless of any controller drivers being enabled.

This fixes compile warnings due to missing prototypes on ARCHs where
the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers.

One could argue that in the case of no controllers CONFIG_DM_USB should not
be set, but this problem is typically seen during bringup of boards which
do actually have usb controllers.

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read
U-Boot from raw memory. Thus, there is no reason to provide a sector or
partition for raw mode. This allows this behaviour and still provides a robust
fallback mechanism in case provisions for both modes are defined.

When building tools-only (or env) we need to be sure that we do use
<linux/kconfig.h> and do not use <generated/autoconf.h>.  This will fix

then 'make tools-only'.

Based on the responses below to the thread add linux/kconfig.h higher in
