Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.
This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND
to store the environment variables, would lead to the following error:
NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB
Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.
If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.
This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:
nand-bus-width : 8 or 16 bus width if not present 8

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.

Previously we didn't support upload/download larger than available
memory. This is pretty bad when you have to update your root filesystem
for example.
This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.
The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.
Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

One usecase which is broken because of this feature is that Ether

CONFIG_USB_GADGET_DUALSPEED)
After desabled this feature, MUSB driver send packets in proper size

Reviewing the ECSPI reset handling shows two issues:
1. For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg
(ECSPIx_CONGREG) the i.MX6 technical reference manual states:
-- cut --
ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block
and resets the internal logic with the exception of the ECSPI_CONREG.
-- cut --
Note the exception mentioned: The CONREG itself isn't reset.
Fix this by manually writing the reset value 0 to the whole register.
This sets the EN bit to zero, too (i.e. includes the old
~MXC_CSPICTRL_EN).
2. We want to reset the whole SPI block here. So it makes no sense
to first read the old value of the CONREG and write it back, later.
This will give us the old (historic/random) value of the CONREG back.
And doesn't reset the CONREG.
To get a clean CONREG after the reset of the block, too, don't use
the old (historic/random) value of the CONREG while doing the reset.
And read the clean CONREG after the reset.
This was found while working on a SPI boot device where the i.MX6 boot
ROM has already initialized the SPI block. The initialization by the
boot ROM might be different to what the U-Boot driver wants to configure.
I.e. we need a clean reset of SPI block, including the CONREG.

Maximum bus width supported by some i.MX6 boards is not 8bit like
others. In case where both host controller and card support 8bit transfers,
they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.
It is tested with a MMCplus card.

This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0. The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.
I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus. I have not tested the case where there's an 8-bit part on a 16-bit
bus.
This patch also adds some delays as suggested by Spansion.
If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.
Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.
