Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in
SPL. These #defines do not allow the user to select SPI mode for the SPI flash
(there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in
spi_spl_load.c), and duplicate information already provided by
CONFIG_SF_DEFAULT_* #defines.
Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.

After mtd was synced with Linux 3.14
(ff94bc40af3481d47546595ba73c136de6af6929)
the number of parameters for write_page function of nand_chip was
changed. The additional two var were needed for subpage write.
As keystone has no supbage write they are not needed. So correct
only function definition by upgrading it's parameter list.
That helps to get ritd of compilation warning.

U-Boot has imported various source files from other projects,
mostly Linux.
Something like
#ifdef __UBOOT__
[ modification for U-Boot ]
#else
[ original code ]
#endif
is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.
Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

OMAP GPMC driver used with some NAND Flash devices (e.g. Spansion
S34ML08G1) causes that U-boot shows hundreds of 'nand: bit-flip
corrected' error messages. Possible cause was discussed in the
mailinglist thread:
http://lists.denx.de/pipermail/u-boot/2014-April/177508.html
Quote (Author: Pekon Gupta <pekon@ti.com>): "The issue is mainly
due to a NAND protocol violation in the omap driver since the
Random Data Output command (05h-E0h) expects to see only the
column address that should be addressed within the already loaded
read page into the read buffer. Only 2 address cycles with ALE
active should be provided between the 05h and E0h commands. The
Page read command expects the full address footprint (2bytes for
column address + 3bytes for row address), but once the page is
loaded into the read buffer, Random Data Output should be used
with only 2bytes for column address."
This patch combines the solution proposed in the mailinglist and
the patch provided by the Spansion company (GPLv2 code, source:
http://www.spansion.com/Support/Software/u-boot-psp-04.04.00.01-NAND.zip)

Since the CS of a device connected to the GPMC was
stored in the global variable, it was not possible to
use multiple devices. In this patch the CS is stored per
device in its 'struct omap_nand_info'. This makes it
possible to use up to 'GPMC_MAX_CS' NAND Flash devices
connected to U-boot.

The Keystone SoCs use the same NAND driver as Davinci.
This patch adds opportunity to write Keystone U-boot image to NAND
device using appropriate RBL ECC layout. This is needed only if RBL
boots U-boot from NAND device and that's supposed that raw u-boot
partition is used only for writing image.
The main problem is that default Davinci ECC layout is different from
Keystone RBL layout. To read U-boot image the RBL needs that image was
written using RBL ECC layout.
The BBT table is written using default Davinci layout and has to
be updated using one. The BBT can be updated only while erasing
chip or by forced bad block assigning, so erase function has to
use native ecc layout in order to be able to write BBT correctly.
So if we're writing to NAND U-boot address we use RBL layout for
others we use default ECC layout.
Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no
reasons to use ECC layout commands. It was added by mistake.

This patch add support for BCH16_ECC to omap_gpmc driver.
*need to BCH16 ECC scheme*
With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes
Flash devices have become more suspectible to bit-flips. Thus stronger
ECC schemes are required for protecting the data.
But stronger ECC schemes have come with larger-sized ECC syndromes which require
more space in OOB/Spare. This puts constrains like;
(a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data.
(b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B.
Due to (b) this scheme can only be used with NAND devices which have enough
OOB to satisfy following equation:
OOBsize per page >= 26 * (page-size / 512)

bus-width
GPMC controller needs to be configured based on bus-width of the NAND device
connected to it. Also, dynamic detection of NAND bus-width from on-chip ONFI
parameters is not possible in following situations:
SPL: SPL NAND drivers does not support ONFI parameter reading.
U-boot: GPMC controller iniitalization is done in omap_gpmc.c:board_nand_init()
which is called before probing for devices, hence any ONFI parameter
information is not available during GPMC initialization.
Thus, OMAP NAND driver expected board developers to explicitely write GPMC
configurations specific to NAND device attached on board in board files itself.
But this was troublesome for board manufacturers as they need to dive into
lengthy platform & SoC documents to find details of GPMC registers and
appropriate configurations to get NAND device working.
This patch instead adds existing CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config
hich indicates that connected NAND device has x16 bus-width. And then based on
this config GPMC driver itself initializes itself based on NAND bus-width. This
keeps board developers free from knowing GPMC controller specific internals.

As per following Sections in ONFI Spec, NAND_CMD_READID should use only
lower 8-bit for transfering command, address and data even on x16 NAND device.
*Section: Target Initialization"
"The Read ID and Read Parameter Page commands only use the lower 8-bits of the
data bus. The host shall not issue commands that use a word data width on x16
devices until the host determines the device supports a 16-bit data bus width
in the parameter page."
*Section: Bus Width Requirements*
"When the host supports a 16-bit bus width, only data is transferred at the
16-bit width. All address and command line transfers shall use only the lower
8-bits of the data bus. During command transfers, the host may place any value
on the upper 8-bits of the data bus. During address transfers, the host shall
set the upper 8-bits of the data bus to 00h."
Thus porting following commit from linux-kernel to ensure that column address
is not altered to align to x16 bus when issuing NAND_CMD_READID command.
commit 3dad2344e92c6e1aeae42df1c4824f307c51bcc7
mtd: nand: force NAND_CMD_READID onto 8-bit bus
Author: Brian Norris <computersforpeace@gmail.com> (preserving authorship)
The NAND command helpers tend to automatically shift the column address
for x16 bus devices, since most commands expect a word address, not a
byte address. The Read ID command, however, expects an 8-bit address
(i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or
0x20).
This fixes the column address for a few drivers which imitate the
nand_base defaults.

mtd: nand: don't use read_buf for 8-bit ONFI transfers
Use a repeated read_byte() instead of read_buf(), since for x16 buswidth

SPI driver perform its operation(read/write) on 64KB buffer chunk for data
greater than 64KB. This buffer chunk is allocated from system heap.
During SPL boot, 768KB of data is read from SPI flash.
Here, heap size may not be sufficient enough to full-fill 64KB buffer
requirement of SPI driver. So break down u-boot read operation at 8KB of chunk.
Also, fix a warning i.e. "unused variable buf" during CONFIG_FSL_CORENET
